Poetikk og politikk : Augusto Boal og de undertryktes teater Poetics and Politics

Poetics and Politics. AugustoBoal and the Theatre of the Oppressed deals with the ideas and methods of the Brazilian author, director and theatre theorist Augusto Boal. The main purpose of the thesis is to give a description of what can be characterized as the poetics of Augusto Boal. What is the specific nature of his theatre methods and in what way do they differ from traditional theatre? How do these methods actually work? What is the overall intention of the Theatre of the Oppressed? As objects for my research I have selected Forum Theatre and Rainbow of Desire. The reason for this choice is partly that the two methods mentioned have become the most widespread among Boal's theatre forms, partly that they complement each other, the former being a method that works with problems of the material world, in realistic action-based narratives; the latter being an expressionistic analytical method, designed to deal with psychological problems and internalized oppression. Going from a micro- to a macro-level, I first examine the theatrical text of both forms, which in this case includes not only the verbal narrative, but also the performance itself and the setting of it, and even the implied conditions of the whole theatrical situation. Secondly, I turn to the encounter between the text and its actual recipient in the theatrical space. What happens, psychologically, when the observing, but passive spectator is turned into the actor of the play? Thirdly, I discuss the ideological and political implications of the Theatre ofthe Oppressed in real life. The way I interpret Boal's poetics, this is of vital importance. The purpose of the Theatre of the Oppressed is not anything resembling l'art pour l'art. In the contrary, its intention is to teach the oppressed the use of theatre as a martial art, so that they can fight and break the oppression in a social context of the real world. Thus the title Poetics and Politics.

Palvelun laadun dimensiot ja asiakastyytyväisyys osuuskuntamuotoisissa opinnoissa

Saimaan ammattikorkeakoulun uudessa Luotsi-toimintamallissa opiskelijat oppivat yritysten antamia toimeksiantoja toteuttamalla. Opiskelijat perustavat oman osuuskuntamuotoisen tiimiyrityksen. Suuri osa opetussuunnitelman opintojaksoista toteutetaan tehden asiakasprojekteja. Tutkielman päätavoitteena on selvittää, mitkä ovat palvelun laadun dimensiot osuuskuntamuotoisissa opinnoissa ja millaisina opiskelijat ne kokevat. Tavoitteina on myös käsitellä tapaa, joilla palvelun laatu muodostuu korkeakouluissa sekä tutkia miksi asiakastyytyväisyyttä mitataan ja millaiseksi se koetaan. Teorian pohjalta päädytään tarkastelemaan viittä koulutuksen dimensiota, jotka ovat osa korkeakoulun palvelun laatua ja vaikuttavat asiakastyytyväisyyteen: opetussuunnitelma, oppimisympäristöt, opetusmenetelmät, ohjaus ja opetus sekä osaamisen arviointi. Empiirisen tutkimuksen kohderyhmänä on Luotsi-mallissa aloittanut liiketalouden pilottiryhmä. Tutkimuksessa käytetään kyselylomaketta sekä teemahaastattelua ryh-mälle. Kyselylomake koostuu 108 kysymyksestä, jotka on jaettu kolmeen osaan: tärkeyden, odotusten ja nykytilan arviointiin seitsenportaisella Li-kert-asteikolla. Haastattelun avulla syvennetään aineistoa. Tulokseksi saadaan attribuuttien ja dimensioiden tärkeysjärjestys sekä arvot nykytilalle, odotuksille ja niiden erotukselle. Tulosten pohjalta nostetaan esiin attribuutit, jotka tarvitsevat eniten kehitystoimia. Tutkimusten perusteella voidaan todeta, että eniten kehitystä vaatii ope-tussuunnitelma ja siihen välillisesti liittyvät attribuutit muista dimensioista. Suurin kynnys Luotsi-toimintamallin onnistumiselle on saavuttaa opiskelijoiden ja opettajien välille toimiva keskusteluyhteys sekä kehittää jatkuvasti opetussuunnitelmaa työelämälähtöisemmäksi.

Pelillistäminen menetelmänä julkisen liikenteen käytön lisäämisessä

Joukkoliikenteen suosio hiipuu vähitellen, käyttö aste laskee. Tätä ongelmaa lähdimme ratkaisemaan sovelluksen ja pelillistämis menetelmän avulla. Menetelmää hyödyntäen tavoitteena oli luoda sovellus joka koukuttaa käyttäjän sovelluksen käyttöön ja sitä kautta joukkoliikenteen käyttöön. Pyrimme pysäyttämään joukkoliikenteen käyttöasteen laskun tai jopa kääntämään sen kasvuun. Varsinaista tulosta ei tällä työllä saatu, sillä aika ei vain riittänyt sovelluksen testaamiseen käytännössä. Pelillistämis menetelmiä kun tutkii ja vertaa sovellustamme niihin, niin sovelluksellamme on hyvä mahdollisuudet toimia joukkoliikenteen käytön lisäämisen työkaluna.

Usability metric design for prenatal healthcare information system

This work goes through the concept of usability in general and healthcare, especially prenatal healthcare, context. Different frameworks and guidelines used to measure it are considered. A collection of metrics is suggested to be used at a prenatal unit of one Finnish healthcare district. The metrics consist of a set of 12 general measures and a supplementary System Usability Scale questionnaire including a Fun Toolkit Smileyometer. The metrics are tested in real life work situations by observing meetings with patients and presenting the questionnaire for the focus group personnel. A total of 6 focus group patient meetings were observed. This work suggests that in order to get more conclusive data from the metrics the focus groups need to be more involved and observation situations need to be more controlled. Revised metrics consist of the 12 general measures.

Development and characterization of thin printed films for gas sensing applications

The monitoring and control of hydrogen sulfide (H2S) level is of great interest for a wide range of application areas including food quality control, defense and antiterrorist applications and air quality monitoring e.g. in mines. H2S is a very poisonous and flammable gas. Exposure to low concentrations of H2S can result in eye irritation, a sore throat and cough, shortness of breath, and fluid retention in the lungs. These symptoms usually disappear in a few weeks. Long-term, low-level exposure may result in fatigue, loss of appetite, headache, irritability, poor memory, and dizziness. Higher concentrations of 700 - 800 ppm tend to be fatal. H2S has a characteristic smell of rotten egg. However, because of temporary paralysis of olfactory nerves, the smelling capability at concentrations higher than 100 ppm is severely compromised. In addition, volatile H2S is one of the main products during the spoilage of poultry meat in anaerobic conditions. Currently, no commercial H2S sensor is available which can operate under anaerobic conditions and can be easily integrated in the food packaging. This thesis presents a step-wise progress in the development of printed H2S gas sensors. Efforts were made in the formulation, characterization and optimization of functional printable inks and coating pastes based on composites of a polymer and a metal salt as well as a composite of a metal salt and an organic acid. Different processing techniques including inkjet printing, flexographic printing, screen printing and spray coating were utilized in the fabrication of H2S sensors. The dispersions were characterized by measuring turbidity, surface tension, viscosity and particle size. The sensing films were characterized using X-ray photoelectron spectroscopy, X-ray diffraction, atomic force microscopy and an electrical multimeter. Thin and thick printed or coated films were developed for gas sensing applications with the aim of monitoring the H2S concentrations in real life applications. Initially, a H2S gas sensor based on a composite of polyaniline and metal salt was developed. Both aqueous and solvent-based dispersions were developed and characterized. These dispersions were then utilized in the fabrication of roll-to-roll printed H2S gas sensors. However, the humidity background, long term instability and comparatively lower detection limit made these sensors less favourable for real practical applications. To overcome these problems, copper acetate based sensors were developed for H2S gas sensing. Stable inks with excellent printability were developed by tuning the surface tension, viscosity and particle size. This enabled the formation of inkjet-printed high quality copper acetate films with excellent sensitivity towards H2S. Furthermore, these sensors showed negligible humidity effects and improved selectivity, response time, lower limit of detection and coefficient of variation. The lower limit of detection of copper acetate based sensors was further improved to sub-ppm level by incorporation of catalytic gold nano-particles and subsequent plasma treatment of the sensing film. These sensors were further integrated in an inexpensive wirelessly readable RLC-circuit (where R is resistor, L is inductor and C is capacitor). The performance of these sensors towards biogenic H2S produced during the spoilage of poultry meat in the modified atmosphere package was also demonstrated in this thesis. This serves as a proof of concept that these sensors can be utilized in real life applications.

From statin efficacy to everyday effectiveness: Studying the gap in between.

Statins are indicated for preventing cardiovascular disease events. Patients with diabetes have a risk of major cardiovascular events double the risk of their peers without diabetes. Thus, clinical treatment guidelines recommend statins for the management of diabetic dyslipidemia. The evidence base for statin use in cardiovascular disease derives from the randomized controlled statin trials designed to prove statin efficacy under ideal conditions, among a homogenous study population meeting strict trial eligibility criteria. This thesis was implemented as four pharmacoepidemiological statin studies using register data on realworld statin users. The overall purpose was to evaluate the trends, patterns and effectiveness of statin use in everyday life. More specifically, nationwide secular trends in statin use in Finland were analysed, especially among patient groups which had been underrepresented in the statin trials. Furthermore, the benchmarking statin trials in diabetes, the Heart Protection Study and the Collaborative Atorvastatin Diabetes Study, were evaluated for their representativeness for real-world diabetes care with the emphasis placed on adherence to statin use. The association between good adherence and the incidence of major cardiovascular events in the real-world was further investigated in diabetes. These studies demonstrate that statin initiations increased from 1995 to 2005 in Finland. The increase was most pronounced among those aged at least 75 years and was observed already before the publication of rigorous trial data conducted in elderly subjects. Thus, statins seem to have been initiated in clinical practice also going beyond the strict trial eligibility criteria. Nonetheless, low adherence to statin use among the real-world patients with diabetes was found not only to limit the representativeness of the trials for clinical care but also to attenuate in all likelihood their benefits in the real-world. In fact, good adherence to statin use was found to associate with a decreased risk for major cardiovascular events in patients with diabetes. In conclusion, these studies highlight the importance of good adherence to statin use in clinical practice in order to obtain the full therapeutic value demonstrated in the statin trials. Simply increasing the number of statin users will not alone suffice in sharing our common resources appropriately.
