Resa i röstens landskap : en narrativ studie av hur lärare blir professionella röstanvändare

The theme of this thesis is the learning process that occurs when teachers become professional voice users. The aim is to explore what it (really) means to become a professional voice user in a teaching profession; thereby developing an understanding of how future education in this field can be arranged so as to both effectively prevent vocal problems and to develop oral didactical competence among teachers. The ambition is to describe, interpret, and understand the learning process through a combination of emic and ethic research perspectives. The theoretical frame of reference reflects the cross disciplinary character of the thesis. Voice problems are common among both student teachers and inservice teachers and adversely affect professional competence, identity and quality of life. Additionally, vocal problems are proven to have a negative impact on pupils´ learning. The individual elements of learning are explored in the light of experiential learning theory and transformative learning theory. The social elements of learning are explored in relation to the theory of situated learning. In addition, theories of teacher professionalisation in terms of competence and identity are outlined. The empirical study has a longitudinal and multi method character. It is anchored in a phenomenological hermeneutical tradition, more specifically in narrative inquiry. The point of departure is the learning experiences of ten student teachers, who attended a ten week long course on voice production as part of their teacher training at Åbo Akademi University, in the autumn of 2002 and the spring of 2003. Four interviews in the form of conversations were conducted with each participant. These were crystallised with a process diary, a Swedish Voice Handicap Index, a voice observation, and a video observation. A fifth interview was conducted with each participant five years post teacher training, in the spring of 2008. Participant observation was also conducted throughout the course. The research materials have been analysed and interpreted narratively using a phenomenological hermeneutical method. The results are presented descriptively as individual narratives, which are reflected in logopedic research materials. Learning is here understood as emergent awareness. This is followed by a meta narrative concerning learning as experiences in the four dimensions body, thought, feeling, and relation. Finally, interpretation is expressed with respect to the theory of relational education. Learning is here understood as a movement in the field between the actual and the possible voice. It is also viewed as fundamentally rooted in inter-human relationships, in moments of presence and coexistence. As a tentative answer to the call for an existential space for learning in order to be a professional voice user, I suggest the concept of a learning refuge as a locus for a learning process built on trust, mutuality and openness.

High-Throughput Screening for Novel Prostate Cancer Drug Targets –Getting Personal

Prostate cancers form a heterogeneous group of diseases and there is a need for novel biomarkers, and for more efficient and targeted methods of treatment. In this thesis, the potential of microarray data, RNA interference (RNAi) and compound screens were utilized in order to identify novel biomarkers, drug targets and drugs for future personalized prostate cancer therapeutics. First, a bioinformatic mRNA expression analysis covering 9873 human tissue and cell samples, including 349 prostate cancer and 147 normal prostate samples, was used to distinguish in silico prevalidated putative prostate cancer biomarkers and drug targets. Second, RNAi based high-throughput (HT) functional profiling of 295 prostate and prostate cancer tissue specific genes was performed in cultured prostate cancer cells. Third, a HT compound screen approach using a library of 4910 drugs and drug-like molecules was exploited to identify potential drugs inhibiting prostate cancer cell growth. Nine candidate drug targets, with biomarker potential, and one cancer selective compound were validated in vitro and in vivo. In addition to androgen receptor (AR) signaling, endoplasmic reticulum (ER) function, arachidonic acid (AA) pathway, redox homeostasis and mitosis were identified as vital processes in prostate cancer cells. ERG oncogene positive cancer cells exhibited sensitivity to induction of oxidative and ER stress, whereas advanced and castrate-resistant prostate cancer (CRPC) could be potentially targeted through AR signaling and mitosis. In conclusion, this thesis illustrates the power of systems biological data analysis in the discovery of potential vulnerabilities present in prostate cancer cells, as well as novel options for personalized cancer management.

Päämääriä, ajelehtimista, tietämättömyyttä, etsintää: Koulutusvalinnat, opinnot ja koulutuksen vaihtaminen yliopisto-opiskelijoiden kokemana 2000 -luvun taitteessa

Tutkimuksessa tarkastellaan yliopisto-opiskelua, opintojen kokemista ja niiden kulkua alkaen koulutusvalinnoista. Lisäksi tutkimuksessa pyritään ymmärtämään ja kuvaamaan yliopisto-opintojen aikaista koulutuksen vaihtamista prosessina. Kyseessä on seurantatutkimus Turun yliopistossa vuonna 1998 aloittaneesta opiskelijakohortista. Tutkittavat opiskelijat valittiin sillä perusteella, että he vastasivat kolmeen opintoja koskevaan kyselyyn ja olivat vähintään kolmen vuoden ajan läsnä olevina opiskelijoina. Opiskelijat (n=440) jaettiin neljään vertailuryhmään: 1) opintoihinsa tyytyväiset, 2) ensimmäisen vuoden jälkeen koulutusta vaihtaneet, 3) toisen vuoden jälkeen koulutusta vaihtaneet ja 4) koulutusta vaihtaa halunneet. Tutkimusaineisto koostuu kolmesta kyselystä, opintorekisteriaineistosta ja koulutusta opintojen aikana vaihtaneiden opiskelijoiden haastatteluista (n=22). Kyselyt tehtiin ensimmäisen, toisen ja kolmannen opintovuoden kevätlukukausilla ja haastattelut vuonna 2002, jolloin opiskelijat opiskelivat Turun yliopistossa neljättä tai viidettä vuotta. Kyselyiden avulla tutkittiin eroavatko koulutusta vaihtaneet opiskelijat muista opiskelijoista rakenteellisilta tekijöiltään tai opintokokemuksissaan. Opintorekisteriaineiston perusteella tutkittiin eroavatko koulutusta vaihtaneet opiskelijat koulutuksessa pysyneistä opiskelijoista opintojen kulussa. Kyselyiden ja haastatteluiden avulla tutkittiin minkälaisia tietoja ja odotuksia opiskelijoilla oli yliopisto-opiskelusta ollut ennen opintojen aloittamista. Haastatteluiden perusteella tutkittiin mitä syitä koulutuksen vaihtamisen taustalla oli ja minkälaisina kertomuksina koulutuksen vaihtamisprosessi näyttäytyi. Koulutusta vaihtaneet opiskelijat erosivat koulutuksessa pysyneistä opiskelijoista aiemman koulutuksen määrän, iän ja perheellisyyden suhteen. Verrattaessa ensimmäisen ja toisen vuoden jälkeen koulutusta vaihtaneita opiskelijoita keskenään havaittiin näillä ryhmillä olevan erilainen perhetausta. Koulutusta valittaessa tärkein tekijä oli kiinnostus alaa kohtaan. Toiseksi voimakkain hakutekijä oli muilla paitsi ensimmäisen vuoden jälkeen koulutusta vaihtaneilla valmiudet haluttuun ammattiin. Vuorostaan ensimmäisen vuoden jälkeen koulutusta vaihtaneilla toiseksi tärkein tekijä hakeutumisessa oli helppo sisäänpääsy opintoihin. Suurin osa opiskelijoista oli päässyt ensisijaisesti haluamaansa koulutukseen. Koulutusta myöhemmin vaihtaneissa ryhmissä ja koulutuksen vaihtoa halunneiden ryhmässä ensisijaisesti haluttuun koulutukseen päässeitä oli alle puolet. Odotukset opiskelusta eivät täysin täyttyneet ensimmäisen puolen vuoden opiskelun aikana. Tutkittujen ryhmien välillä havaittiin eroja kokemuksissa koulutuksen sopivuudesta itselle. Koulutuksen vaihtaminen oli myönteinen kokemus, ja uusi koulutus koettiin aiempaa koulutusta sopivammaksi itselle. Kolmannen vuoden kevätlukukaudella omaa koulutusta kohtaan koettu kiinnostus oli voimakasta muissa ryhmissä paitsi koulutuksen vaihtoa halunneissa. Harvimmin positiivisia tunteita opiskelua kohtaan kokivat vaihtoa halunneet opiskelijat. Koulutuksen vaihtaminen vähensi opintoihin kiinnittymättömyyttä. Koulutuksen vaihtoa halunneiden kokemukset nykyisen koulutuksensa ilmapiiristä olivat negatiivisimpia. Koulutuksen vaihtaminen vaikutti myönteisesti myös opetuksen kokemiseen. Opinnot etenivät kaikissa tutkituissa ryhmissä tasaisesti. Koulutuksen vaihtamisen jälkeisenä vuonna opinnot etenivät vaihtaneissa ryhmissä keskimääräistä enemmän. Haastatteluiden mukaan pääasiallisia syitä koulutuksen vaihtamiselle olivat päätyminen toissijaiseen koulutukseen ja pettyminen aloittamaansa koulutukseen. Narratiivien analyysin avulla tutkimuksessa löydettiin neljä erilaista tarinaa vaihtamisprosessista: 1) toissijaisesta koulutuksesta ensisijaiseen koulutukseen vaihtaminen, 2) ensisijaiseen koulutukseen pettyminen, 3) kiinnostavampaan koulutukseen ajautuminen ja 4) oman alan löytyminen etsinnän kautta. Vaikka koulutuspolitiikassa koulutuksen vaihtaminen nähdään ongelmana, oli se tämän tutkimuksen mukaan opiskelijalle myönteinen kokemus. Tämän tutkimuksen perusteella tulisikin kiinnittää huomiota opiskelijoihin, jotka haluaisivat vaihtaa koulutuksesta toiseen. Heillä opintojen eteneminen osoittautui hitaimmaksi ja opintokokemukset negatiivisimmiksi. Koulutusta vaihtaneiden opiskelijoiden opintojen eteneminen näytti hitaalta verrattuna opintoihinsa tyytyväisiin opiskelijoihin. Koulutuksen vaihtamisen jälkeen opintojen eteneminen kuitenkin nopeutui ja opintotyytyväisyys lisääntyi.

Socially Competent Leadership - predictors, impacts and skilling in engineering

Earlier management studies have found a relationship between managerial qualities and subordinate impacts, but the effect of managers‘ social competence on leader perceptions has not been solidly established. To fill the related research gap, the present work embarks on a quantitative empirical effort to identify predictors of successful leadership. In particular, this study investigates relationships between perceived leader behavior and three selfreport instruments used to measure managerial capability: 1) the WOPI Work Personality Inventory, 2) Raven‘s general intelligence scale, and 3) the Emotive Communication Scale (ECS). This work complements previous research by resorting to both self-reports and other-reports: the results acquired from the managerial sample are compared to subordinate perceptions as measured through the ECS other-report and the WOPI360 multi-source appraisal. The quantitative research is comprised of a sample of 8o superiors and 354 subordinates operating in eight Finnish organizations. The strongest predictive value emerged from the ECS self- and other-reports and certain personality dimensions. In contrast, supervisors‘ logical intelligence did not correlate with leadership perceived as socially competent by subordinates. 16 of the superiors rated as most socially competent by their subordinates were selected for case analysis. Their qualitative narratives evidence the role of life history and post-traumatic growth in developing managerial skills. The results contribute to leadership theory in four ways. First, the ECS self-report devised for this research offers a reliable scale for predicting socially competent leader ability. Second, the work identifies dimensions of personality and emotive skills that can be considered predictors of managerial ability and benefited from in leader recruitment and career planning. Third, the Emotive Communication Model delineated on the basis of the empirical data allows for a systematic design and planning of communication and leadership education. Fourth, this workfurthers understanding of personal growth strategies and the role of life history in leader development and training. Finally, this research advances educational leadership by conceptualizing and operationalizing effective managerial communications. The Emotive Communication Model devised directs the pedagogic attention in engineering to assertion, emotional availability and inspiration skills. The proposed methodology addresses classroom management strategies drawing from problem-based learning, student empowerment, collaborative learning, and so-called socially competent teachership founded on teacher immediacy and perceived caring, all constituting strategies moving away from student compliance and teacher modelling. The ultimate educational objective embraces the development of individual engineers and organizational leaders that not only possess traditional analytical and technical expertise and substantive knowledge but are intelligent also creatively, practically, and socially.

Catalysis by gold for biomass transformations

The development of new technologies to supplement fossil resources has led to a growing interest in the utilization of alternative routes. Biomass is a rich renewable feedstock for producing fine chemicals, polymers, and a variety of commodities replacing petroleumderived chemicals. Transformation of biomass into diverse valuable chemicals is the key concept of a biorefinery. Catalytic conversion of biomass, which reduces the use of toxic chemicals is one of the important approaches to improve the profitability of biorefineries. Utilization of gold catalysts allows conducting reactions under environmentally-friendly conditions, with a high catalytic activity and selectivity. Gold-catalyzed valorization of several biomass-derived compounds as an alternative approach to the existing technologies was studied in this work. Isomerization of linoleic acid via double bond migration towards biologically active conjugated linoleic acid isomers (CLA) was investigated. The activity and selectivity of various gold catalysts towards cis-9,trans-11-CLA and trans-10,cis-12-CLA were investigated in a semi-batch reactor, showing that the yield of the desired products varied, depending on the catalyst support. The structure sensitivity in the selective oxidation of arabinose was demonstrated using a series of gold catalysts with different Au cluster sizes in a shaker reactor operating in a semibatch mode. The gas-phase selective oxidation of ethanol was studied and the influence of the catalyst support on the catalytic performance was investigated. The selective oxidation of the lignan hydroxymatairesinol (HMR), extracted from the Norway spruce (Picea abies) knots, to the lignan oxomatairesinol (oxoMAT) was extensively investigated. The influence of the reaction conditions and catalyst properties on the yield of oxoMAT was evaluated. In particular, the structure sensitivity of the reaction was demonstrated. The catalyst deactivation and regeneration procedures were studied. The reaction kinetics and mechanism were advanced.

Production of Mg(OH)2 from Mg-silicate rock for CO2 mineral sequestration

Sequestration of carbon dioxide in mineral rocks, also known as CO2 Capture and Mineralization (CCM), is considered to have a huge potential in stabilizing anthropogenic CO2 emissions. One of the CCM routes is the ex situ indirect gas/sold carbonation of reactive materials, such as Mg(OH)2, produced from abundantly available Mg-silicate rocks. The gas/solid carbonation method is intensively researched at Åbo Akademi University (ÅAU ), Finland because it is energetically attractive and utilizes the exothermic chemistry of Mg(OH)2 carbonation. In this thesis, a method for producing Mg(OH)2 from Mg-silicate rocks for CCM was investigated, and the process efficiency, energy and environmental impact assessed. The Mg(OH)2 process studied here was first proposed in 2008 in a Master’s Thesis by the author. At that time the process was applied to only one Mg-silicate rock (Finnish serpentinite from the Hitura nickel mine site of Finn Nickel) and the optimum process conversions, energy and environmental performance were not known. Producing Mg(OH)2 from Mg-silicate rocks involves a two-staged process of Mg extraction and Mg(OH)2 precipitation. The first stage extracts Mg and other cations by reacting pulverized serpentinite or olivine rocks with ammonium sulfate (AS) salt at 400 - 550 oC (preferably < 450 oC). In the second stage, ammonia solution reacts with the cations (extracted from the first stage after they are leached in water) to form mainly FeOOH, high purity Mg(OH)2 and aqueous (dissolved) AS. The Mg(OH)2 process described here is closed loop in nature; gaseous ammonia and water vapour are produced from the extraction stage, recovered and used as reagent for the precipitation stage. The AS reagent is thereafter recovered after the precipitation stage. The Mg extraction stage, being the conversion-determining and the most energy-intensive step of the entire CCM process chain, received a prominent attention in this study. The extraction behavior and reactivity of different rocks types (serpentinite and olivine rocks) from different locations worldwide (Australia, Finland, Lithuania, Norway and Portugal) was tested. Also, parametric evaluation was carried out to determine the optimal reaction temperature, time and chemical reagent (AS). Effects of reactor types and configuration, mixing and scale-up possibilities were also studied. The Mg(OH)2 produced can be used to convert CO2 to thermodynamically stable and environmentally benign magnesium carbonate. Therefore, the process energy and life cycle environmental performance of the ÅAU CCM technique that first produces Mg(OH)2 and the carbonates in a pressurized fluidized bed (FB) were assessed. The life cycle energy and environmental assessment approach applied in this thesis is motivated by the fact that the CCM technology should in itself offer a solution to what is both an energy and environmental problem. Results obtained in this study show that different Mg-silicate rocks react differently; olivine rocks being far less reactive than serpentinite rocks. In summary, the reactivity of Mg-silicate rocks is a function of both the chemical and physical properties of rocks. Reaction temperature and time remain important parameters to consider in process design and operation. Heat transfer properties of the reactor determine the temperature at which maximum Mg extraction is obtained. Also, an increase in reaction temperature leads to an increase in the extent of extraction, reaching a maximum yield at different temperatures depending on the reaction time. Process energy requirement for producing Mg(OH)2 from a hypothetical case of an iron-free serpentine rock is 3.62 GJ/t-CO2. This value can increase by 16 - 68% depending on the type of iron compound (FeO, Fe2O3 or Fe3O4) in the mineral. This suggests that the benefit from the potential use of FeOOH as an iron ore feedstock in iron and steelmaking should be determined by considering the energy, cost and emissions associated with the FeOOH by-product. AS recovery through crystallization is the second most energy intensive unit operation after the extraction reaction. However, the choice of mechanical vapor recompression (MVR) over the “simple evaporation” crystallization method has a potential energy savings of 15.2 GJ/t-CO2 (84 % savings). Integrating the Mg(OH)2 production method and the gas/solid carbonation process could provide up to an 25% energy offset to the CCM process energy requirements. Life cycle inventory assessment (LCIA) results show that for every ton of CO2 mineralized, the ÅAU CCM process avoids 430 - 480 kg CO2. The Mg(OH)2 process studied in this thesis has many promising features. Even at the current high energy and environmental burden, producing Mg(OH)2 from Mg-silicates can play a significant role in advancing CCM processes. However, dedicated future research and development (R&D) have potential to significantly improve the Mg(OH)2 process performance.

Structural and operational optimisation : applications in energy systems

In this work mathematical programming models for structural and operational optimisation of energy systems are developed and applied to a selection of energy technology problems. The studied cases are taken from industrial processes and from large regional energy distribution systems. The models are based on Mixed Integer Linear Programming (MILP), Mixed Integer Non-Linear Programming (MINLP) and on a hybrid approach of a combination of Non-Linear Programming (NLP) and Genetic Algorithms (GA). The optimisation of the structure and operation of energy systems in urban regions is treated in the work. Firstly, distributed energy systems (DES) with different energy conversion units and annual variations of consumer heating and electricity demands are considered. Secondly, district cooling systems (DCS) with cooling demands for a large number of consumers are studied, with respect to a long term planning perspective regarding to given predictions of the consumer cooling demand development in a region. The work comprises also the development of applications for heat recovery systems (HRS), where paper machine dryer section HRS is taken as an illustrative example. The heat sources in these systems are moist air streams. Models are developed for different types of equipment price functions. The approach is based on partitioning of the overall temperature range of the system into a number of temperature intervals in order to take into account the strong nonlinearities due to condensation in the heat recovery exchangers. The influence of parameter variations on the solutions of heat recovery systems is analysed firstly by varying cost factors and secondly by varying process parameters. Point-optimal solutions by a fixed parameter approach are compared to robust solutions with given parameter variation ranges. In the work enhanced utilisation of excess heat in heat recovery systems with impingement drying, electricity generation with low grade excess heat and the use of absorption heat transformers to elevate a stream temperature above the excess heat temperature are also studied.

Modeling and Control of the Power Conversion Unit in a Solid Oxide Fuel Cell Environment

In this doctoral thesis, a power conversion unit for a 10 kWsolid oxide fuel cell is modeled, and a suitable control system is designed. The need for research was identified based on an observation that there was no information available about the characteristics of the solid oxide fuel cell from the perspective of power electronics and the control system, and suitable control methods had not previously been studied in the literature. In addition, because of the digital implementation of the control system, the inherent characteristics of the digital system had to be taken into account in the characteristics of the solid oxide fuel cell (SOFC). The characteristics of the solid oxide fuel cell as well the methods for the modeling and control of the DC/DC converter and the grid converter are studied by a literature survey. Based on the survey, the characteristics of the SOFC as an electrical power source are identified, and a solution to the interfacing of the SOFC in distributed generation is proposed. A mathematical model of the power conversion unit is provided, and the control design for the DC/DC converter and the grid converter is made based on the proposed interfacing solution. The limit cycling phenomenon is identified as a source of low-frequency current ripple, which is found to be insignificant when connected to a grid-tied converter. A method to mitigate a second harmonic originating from the grid interface is proposed, and practical considerations of the operation with the solid oxide fuel cell plant are presented. At the theoretical level, the thesis discusses and summarizes the methods to successfully derive a model for a DC/DC converter, a grid converter, and a power conversion unit. The results of this doctoral thesis can also be used in other applications, and the models and methods can be adopted to similar applications such as photovoltaic systems. When comparing the results with the objectives of the doctoral thesis, we may conclude that the objectives set for the work are met. In this doctoral thesis, theoretical and practical guidelines are presented for the successful control design to connect a SOFC-based distributed generation plant to the utility grid.

Nuorten kokemien elämysten yksilölliset ja yhteisölliset merkitykset

Tutkimuksessa tarkastellaan nuorten antamia merkityksiä elämykseksi nimetylle kokemukselle ja tunteelle. Tavoitteena on ollut selvittää elämysten kokemista nuorten näkökulmasta ja suhteuttaa nuorten kokemuksilleen antamia merkityksiä laajemmin nuoruutta ja elämyksien kokemista käsittelevään yhteiskunnalliseen keskusteluun. Elämysten merkityksellistämistä analysoidaan suhteessa identiteetin muodostukseen. Yksilöllisesti koetut elämykset saavat merkityksensä diskursiivisesti rakentuneen todellisuuden ympäröimänä. Tutkimus paikantuu sosiologisen nuorisotutkimuksen ja tunteiden tutkimuksen alaan sekä metodologisesti fenomenologis-konstruktivistisen tutkimuksen alaan. Tutkimuksen taustalla on elämyshakuisuutta käsittelevä teoria. Elämyshakuisuuden tulkinta fenomenologisesta viitekehyksestä tuo käsitteen ymmärtämiseen uuden ulottuvuuden. Elämyshakuisuus kuvaa asennoitumistapaa eli sitä, miten yksilö orientoituu ympäröivään maailmaan. Tällöin ei edellytetä intentionaalisten tekojen tietoista luonnetta. Toiminnalliset prosessit muovautuvat vuorovaikutuksen myötä samaan tapaan kuin ihminen ruumiillisena subjektina muovautuu. Tutkimuksen aineisto koostuu lukion ensimmäisen luokan oppilaiden kirjoituksista (519 kpl), lastensuojeluinstituutioissa ja kuntoutuskeskuksissa asuvien nuorten yksilöteemahaastatteluista (16 nuorta) sekä seikkailualan asiantuntijoiden teemahaastatteluista (20 aikuista). Nuorten kirjoitukset on kerätty vuosina 1996–1997 ja 2002–2003. Aineiston analyysi on aineistolähtöinen. Erilaiset osa-aineistot työssäni avaavat erilaisia näkökulmia elämysten kokemiseen. Aineistojen analyysi ja tutkimukset teoreettiset lähtökohdat ovat rakentuneet analyysin edetessä ja vuorovaikutussuhteessa toisiinsa. Nuorten elämyksiä käsittelevä kerronta on moninaista ja elämyksiä koetaan erilaisissa tilanteissa. Elämykselle ei ole yhtä määritelmää, kokemisen paikkaan tai kokemisen syytä vaan kokemuksen merkitys rakentuu tilanteisesti. Elämys kuitenkin erottuu muista kokemuksista sen muistettavuuden, ainutlaatuisuuden, uutuuden ja intensiivisyyden perusteella. Nuorten elämyksellisissä hetkissä korostuvat harrastusten yhteydessä koetut uudet, erilaiset, yhteisöllisesti jaetut, mutta myös maailmaa nuorille avaavat itsenäisyyden tunnetta ja hallintaa tuottavat kokemukset. Yksi merkittävä uusia elämyksiä ja tietoa tuottava asia nuorten elämässä on seurustelu. Myös matkailu, erilaiset retket ja leirit olivat nuorille elämyksiä tuottavia tilanteita. Kaikilla nuorilla ei kuitenkaan ole sellaisia harrastuksia, joihin he olisivat sitoutuneita tai joissa he pääsisivät ilmaisemaan itseään ja kokemaan onnistumista. Nuorten elämyksiä käsittelevissä hetkissä nuorten vapaa-ajan toiminta, ympäristö ja sosiaaliset suhteet ovat keskeisessä asemassa. Nuoret eivät ensisijaisesti ajatelleet itse etsivänsä tai toisten nuorten etsivän elämyksiä viihdeteollisuuden tuottamista asioista. Elämyksissä arvostettiin aitoutta ja koettu tunne määritti sitä, oliko jokin koettu elämyksenä vai ei. Toisaalta erilaisten päihteiden todettiin mahdollisesti tuottavan elämyksiä, mutta niidenkin yhteydessä korostettiin usein muita asioita kokemusta rakentavina. Nuorten elämyskokemuksissa toisten nuorten merkitys, luottamus, läheisyyteen ja hyväksyntään liittyvät kokemukset korostuvat. Myös aikuisten asiantuntijoiden omaa nuoruutta käsittelevät elämykset olivat emotionaaliselta merkitykseltään hyvin samanlaisia kuin tämän päivän nuorten esittämät. Elämyksiksi miellettyjä kokemuksia pidettiin arvokkaina. Niiden uskottiin suuntaavan yksilön toimintaa.

Co-created Mobile Narratives

FM Marjo Mäenpään Turun yliopiston Humanistisen tiedekunnan Kulttuurituotannon ja maisemantutkimuksen digitaalisen kulttuurin oppialalle valmistunut väitöskirja Co-created Mobile Narratives tarkastetaan Porin yliopistokeskuksessa 27. huhtikuuta 2013. Marjo Mäenpää tutkii, kuinka ihmiset tarinallistavat elämänsä, kuvittavat ja jakavat kokemuksiaan toisten ihmisten kanssa mobiilin median avulla. Elämänjulkaisemisesta on tullut ihmisten arkista toimintaa. Mäenpää lähestyy jaettuja kännykkävideotarinoita kolmesta eri näkökulmasta. Hän tutkii tarinoiden rakennetta, julkaisemista ja julkaisevia yhteisöjä narratologian, yhteisöjen toiminnan ja mediantutkimuksen valossa. Teoreetikot aina Aristoteleesta klassisen narratologian tutkijoihin ovat esittäneet erilaisia tarinallisuuden kaavoja ja rakenteita, joita on havaittavissa myös yhteisössä tuotetuista videotarinoista. Myöhemmän alan tutkimustradition, mm. kognitiivisen narratologian mukaan ihmiset hahmottavat tarinallisia kokonaisuuksia pienemmistäkin fragmenteista ja vihjeistä. Elämän tarinaa, käännekohtia ja elämyksiä kerrotaan usein – esimerkiksi Facebookissa – yksittäisillä, sattumanvaraisilla kuvilla. Yhteisöllinen tuotanto edellyttää luottamusta. Yhteisö jakaa tarinoita, jotka voivat olla hyvinkin fragmentaarisia, mutta saavat merkityksensä yhteisestä kokemusmaailmasta ja kulttuurista. Julkaiseminen on sattumanvaraista, luovaa toimintaa, jonka lopputulos voi olla ennalta arvaamaton. Kuitenkin julkaiseminen edellyttää jonkinlaista aktiivista toimijaa tai tuottajaa. Rakenteen julkaisemiselle voi antaa tuottaja, moderaattori tai hyvin rakennettu teknologinen julkaisualusta. Monitieteisen väitöstutkimuksen aineisto on peräisin Turun yliopiston, Tampereen teknillisen yliopiston ja Aalto- yliopiston Porin yksiköiden yhteisestä Mobile Social Media -tutkimushankkeesta. Vuosina 2008-2010 hankkeessa suunniteltiin MoViE (Mobile Video Experience) -sovellusta, jonka avulla ihmiset voivat julkaista omia lyhyitä videoitaan ja jakaa niitä toisten käyttäjien kanssa. MoViE-sovelluksen avulla käyttäjät voivat editoida omia ja toisten kuvaamia videoita sekä julkaista kuvallisia tarinoita yhteisöllisistä kokemuksista. MoViE-sovellusta kokeiltiin mm. Pori Jazz -konserteissa. Samasta konsertista taltioitui kännykkävideoille useita näkökulmia, ja testikäyttäjäryhmä koosti useita erilaisia videotarinoita yhteisestä konserttikokemuksestaan. Marjo Mäenpää (1959) työskentelee opetus- ja kulttuuriministeriössä kulttuuriasiainneuvoksena. Hän on toiminut mm. kustantajana, multimedian dramaturgian opettajana Teatterikorkeakoulussa, digitaalisen mediatuotannon professorina Aalto-yliopiston Taiteen ja suunnittelun korkeakoulussa vuosina 2006-2012 sekä Taiteen edistämiskeskuksen väliaikaisena johtajana vuonna 2013.

Product placement on personal blogs: a multiple case study from companies’ perspective
