Työlähtöiset menetelmät työterveyshuollossa : Oppimisen johtaminen uuden toimintakonseptin käyttöönotto- ja vakiinnuttamisvaiheessa

Working life is changing. The core of the change is change in the production and service concepts of organizations. Changes at work are connected to problems in the well-being of employees. To respond to this challenge, occupational health care must develop a course of action. A group of occupational health care units has developed new activity theory-based methods, the object of which is to change the service concept of occupational health care. The focus is on the changes and disturbances in work activity. My aim was to study this development from the perspective of knowledge management; to clarify directors'/ managers' conceptions of the content and object of their managerial work and the tensions included in these conceptions; to examine the learning process involved in these methods and to bring to light the problems, developmental needs and challenges during the implementation and consolidation phases of the process. This was a case study which included 10 occupational health care units using or being trained to use activity theory-based methods. My data consisted of interviews with directors/managers and recordings of the meetings; 20 directors/ managers are represented; I interviewed seven directors/ managers who represented four units. Directors'/ managers' conceptions of the content and object of managerial work were divided into eight categories of description, which I connected to the historical forms of organizations and types of management. Intuitive and rational management are historically older forms of management. The categories of description representing intuitive and rational management contained many internal tensions, i.e. they do not satisfy the demands of the environment. On the other hand, the categories of description which represented management by results and the control of the development process contained very few or no tensions at all; they are effective in the present environment of occupational health care. The learning process of activity theory-based methods has been expansive in nature. The occupational health care units studied are in different phases of the learning process, and these processes have been different. In three units the focus was on work development; in one unit the focus was on development of the service concept. The most central problems, challenges and developmental needs during the implementation phase were related to learning and spreading of methods inside one's own unit, and during the consolidation phase to working with partners.

Asiakassuhteiden johtaminen ja sen merkitys Valion kuluttajapalvelun arvioinnissa ja kehittämisessä

Tutkielman kohdeilmiönä tarkasteltiin asiakassuhdejohtamista ja asiakassuhteen ulottuvuuksia palvelukontekstissa. Tavoitteena oli selvittää, mikä merkitys asiakassuhteiden johtamisella on Valion kuluttajapalvelun arvioinnissa ja kehittämisessä. Valion kuluttajapalvelua tarkasteltiin asiakassuhdejohtamisen osaprosessina. Tutkimuksen teoriaosassa tutustuttiin asiakassuhtejohtamisen taustalla vaikuttaviin näkökulmiin ja määrittelyihin. Asiakassuhteiden johtamista kuvattiin erilaisten prosessimallien avulla yrityksen toimintojen näkökulmasta. Lisäksi tarkasteltiin asiakassuhteen ulottuvuuksia, kuten palvelutarjoomaa, vuorovaikutusta, tyytyväisyyttä, luottamusta sekä uskollisuutta ja sitoutumista. Lopuksi tarkasteltiin arvoa käsitteenä ja arvon merkitystä palvelukontekstissa. Teoriaosan perusteella asiakassuhdejohtaminen on kokonaisvaltainen prosessi, jonka tavoitteena ovat tuottavat ja pitkäkestoiset asiakassuhteet. Yritykseltä vaaditaan kykyä nähdä ja havaita asiakkaiden tarpeita ja mieltymyksiä. Asiakkaan kokema arvo voi välittyä itse palvelusta, prosesseista, ihmisistä, vuorovaikutuksesta, kanavista ja niin edelleen. Myönteisten kokemusten lisääminen palvelu¬prosessin aikana kasvattaa asiakkaan tyytyväisyyttä. Empiirinen osa toteutettiin tapaustutkimuksena, jossa tutkimuskohteena oli Valion kuluttajapalvelu. Tavoitteena oli kerätä tietoa asiakkaiden kokemuksista kuluttajapalvelussa asioinnista. Tutkittavina kohteina olivat asiakasprosessi ja sen sujuvuus, palvelutarjooman sisältö, vuorovaikutus prosessin aikana, asiakkaan kokema tyytyväisyys sekä luottamus yritystä ja sen palvelua kohtaan. Tutkimusaineisto koostui kymmenestä teemahaastattelusta. Haastateltavat olivat olleet yhteydessä Valion kuluttajapalveluun Internetin välityksellä vuoden 2010 aikana. Tutkimustulokset osoittavat, että Valion kuluttajapalvelu nähtiin kanavana, joka vahvistaa ja ylläpitää asiakkaiden suhdetta Valion kanssa. Ihmiset kuluttajapalvelussa nähdään merkittävinä myötävaikuttajina asiakkaiden tyytyväisyyteen ja pysyvyyteen samalla kun ovat vuorovaikutuksessa heidän kanssaan. Kuluttajapalvelun käyttö koettiin helpoksi ja Internet kanavana tuntui joustavalta. Palvelulta odotettiin ensisijaisesti palautteen vastaanottamisen lisäksi ongelmanratkaisua ja tuotetietousneuvontaa. Asiantuntijuus, palvelun nopeus sekä asiakkaan kuunteleminen tulivat esille tärkeimpinä palvelutekijöinä. Haasteena Valion kuluttajapalvelulle nousi esiin asiakaspalvelijan kyky havaita ja ymmärtää asiakkaan kokemien uhrausten määrä sekä kyky vastata niihin oikealla palvelutarjoomalla eli hyötyjen muodostamalla kokonaisuudella. Asiakaspalvelijan toimintaa kuvasi asiallisuus, virallisuus, huomioon ottava tyyli sekä yleinen ystävällisyys. Tutkimustulosten mukaan Valion kuluttajapalvelulla on olemassa keskeiset arvoa tuottavat palvelutekijät, mutta niiden toimivuus strategisina yhdistelminä asettaa haasteita jokaiseen palvelukohtaamiseen asiakkaan kanssa. Asiakkaan arvo-odotukset eivät aina olleet niitä, joita palvelukohtaamisessa oli realisoitunut. Tulosten perusteella voidaan todeta, että mitä paremmin Valion kuluttajapalvelu huomioi myös asiakkaiden emotionaaliset tarpeet, sitä suurempi on sen tuottama arvo asiakkaalle ja sitä kautta koko yritykselle.

Heated Nebulizer Microchips for Mass Spectrometry

Miniaturized analytical devices, such as heated nebulizer (HN) microchips studied in this work, are of increasing interest owing to benefits like faster operation, better performance, and lower cost relative to conventional systems. HN microchips are microfabricated devices that vaporize liquid and mix it with gas. They are used with low liquid flow rates, typically a few µL/min, and have previously been utilized as ion sources for mass spectrometry (MS). Conventional ion sources are seldom feasible at such low flow rates. In this work HN chips were developed further and new applications were introduced. First, a new method for thermal and fluidic characterization of the HN microchips was developed and used to study the chips. Thermal behavior of the chips was also studied by temperature measurements and infrared imaging. An HN chip was applied to the analysis of crude oil – an extremely complex sample – by microchip atmospheric pressure photoionization (APPI) high resolution mass spectrometry. With the chip, the sample flow rate could be reduced significantly without loss of performance and with greatly reduced contamination of the MS instrument. Thanks to its suitability to high temperature, microchip APPI provided efficient vaporization of nonvolatile compounds in crude oil. The first microchip version of sonic spray ionization (SSI) was presented. Ionization was achieved by applying only high (sonic) speed nebulizer gas to an HN microchip. SSI significantly broadens the range of analytes ionizable with the HN chips, from small stable molecules to labile biomolecules. The analytical performance of the microchip SSI source was confirmed to be acceptable. The HN microchips were also used to connect gas chromatography (GC) and capillary liquid chromatography (LC) to MS, using APPI for ionization. Microchip APPI allows efficient ionization of both polar and nonpolar compounds whereas with the most popular electrospray ionization (ESI) only polar and ionic molecules are ionized efficiently. The combination of GC with MS showed that, with HN microchips, GCs can easily be used with MS instruments designed for LC-MS. The presented analytical methods showed good performance. The first integrated LC–HN microchip was developed and presented. In a single microdevice, there were structures for a packed LC column and a heated nebulizer. Nonpolar and polar analytes were efficiently ionized by APPI. Ionization of nonpolar and polar analytes is not possible with previously presented chips for LC–MS since they rely on ESI. Preliminary quantitative performance of the new chip was evaluated and the chip was also demonstrated with optical detection. A new ambient ionization technique for mass spectrometry, desorption atmospheric pressure photoionization (DAPPI), was presented. The DAPPI technique is based on an HN microchip providing desorption of analytes from a surface. Photons from a photoionization lamp ionize the analytes via gas-phase chemical reactions, and the ions are directed into an MS. Rapid analysis of pharmaceuticals from tablets was successfully demonstrated as an application of DAPPI.

Musiikkifestivaalin toiminnanjohtajan ammattikuva

Tutkimuksen pääkysymyksenä on selvittää, millainen musiikkifestivaalien toiminnanjohtajien ammattikuva on. Asiaa tutkitaan haastattelemalla Kuhmon Kamarimusiikin, Sysmän Suvisoiton ja Tuusulanjärven Kamarimusiikin toiminnanjohtajia sekä tekemällä verkkokysely, joka lähetettiin kaikille Finland Festivals -järjestön jäsenfestivaalien käytännön järjestelyistä vastaaville, olipa heidän työnimekkeenään toiminnanjohtaja, pääsihteeri tms. Työn teoreettisessa osassa (Luku 2) esitellään aiheeseen liittyvät teoreettiset näkökulmat ja Arto Kallioniemen määrittelemät viisi ammattikuvan osa-aluetta. Tutkimuksessa näitä osa-alueita käytetään soveltamalla ne festivaalitoiminnanjohtajien työhön sopiviksi ja liittämällä niihin Timo Rädyn objektiivinen, subjektiivinen ja funktionaalinen ammattikäsitys. Luvussa 3 tutustutaan tutkimuksessa haastateltaviin toiminnanjohtajiin ja heidän johtamiinsa festivaaleihin. Luku 4 alkaa verkkokyselyn tulosten käsittelyllä ja jatkuu perehtymällä toiminnanjohtajien ammattikuvan osa-alueisiin haastattelujen pohjalta. Molempien osien lopussa on yhteenveto. Lisäksi luvun 4 lopussa yhdistetään verkkokyselyn ja haastattelujen tulokset. Viimeisessä luvussa (Luku 5) tutkimustulokset liitetään työn teoreettisiin lähtökohtiin. Verkkokyselyn mukaan keskimääräinen suomalainen musiikkifestivaalin toiminnanjohtaja on akateemisesti koulutettu, noin 45-vuotias nainen, jolla on päätoiminen työsuhde ja joka ansaitsee 2001-2500e/kk. Lisäksi verkkokyselyssä ja haastatteluissa paljastui, että nykyiset toiminnanjohtajat pitävät työhön sopivimpana koulutuksena taiteellista ja taloudellista korkeakoulukoulutusta. Tutkimuksessa selvitettiin myös toiminnanjohtajien työtehtävät, ammattirooli, tietopohja, ammatilliset arvot ja käsitys festivaalijohtajuudesta. Tutkimuksessa laajennetaan musiikkitieteellistä tutkimusta yhteiskunnallisen ja organisatorisen tutkimuksen puolelle. Siinä selvitetään ensi kertaa Suomessa kattavasti, millaisia ihmisiä suomalaisten musiikkifestivaalien johdossa toimii ja tutkitaan millainen koulutus toiminnanjohtajalle parhaiten sopisi. Työstä käy myös ilmi, että musiikkifestivaalin johtaminen vertautuu läheisesti muiden taiteenalojen tapahtumien johtamiseen, mutta myös hieman laajentaen muihinkin kulttuurijohtajuuden aloihin. Samalla tutkimus hahmottelee festivaalijohtajien ammattiyhteisöä.

Oscillatory brain activity in memory disorders

Neuronal oscillations are thought to underlie interactions between distinct brain regions required for normal memory functioning. This study aimed at elucidating the neuronal basis of memory abnormalities in neurodegenerative disorders. Magnetoencephalography (MEG) was used to measure oscillatory brain signals in patients with Alzheimer s disease (AD), a neurodegenerative disease causing progressive cognitive decline, and mild cognitive impairment (MCI), a disorder characterized by mild but clinically significant complaints of memory loss without apparent impairment in other cognitive domains. Furthermore, to help interpret our AD/MCI results and to develop more powerful oscillatory MEG paradigms for clinical memory studies, oscillatory neuronal activity underlying declarative memory, the function which is afflicted first in both AD and MCI, was investigated in a group of healthy subjects. An increased temporal-lobe contribution coinciding with parieto-occipital deficits in oscillatory activity was observed in AD patients: sources in the 6 12.5 Hz range were significantly stronger in the parieto-occipital and significantly weaker in the right temporal region in AD patients, as compared to MCI patients and healthy elderly subjects. Further, the auditory steady-state response, thought to represent both evoked and induced activity, was enhanced in AD patients, as compared to controls, possibly reflecting decreased inhibition in auditory processing and deficits in adaptation to repetitive stimulation with low relevance. Finally, the methodological study revealed that successful declarative encoding and retrieval is associated with increases in occipital gamma and right hemisphere theta power in healthy unmedicated subjects. This result suggests that investigation of neuronal oscillations during cognitive performance could potentially be used to investigate declarative memory deficits in AD patients. Taken together, the present results provide an insight on the role of brain oscillatory activity in memory function and memory disorders.

Reciprocal development of the object and subject of learning. The renewal of the learning practices of front-line communities in a telecommunications company as part of the techno-economical paradigm change. Current changes in production have been seen as an indication of a shift from the techno-economical paradigm of a mass-production era to a new paradigm of the information and communication technological era. The rise of knowledge management in the late 1990s can be seen as one aspect of this paradigm shift, as knowledge creation and customer responsiveness were recognized as the prime factors in business competition. However, paradoxical conceptions concerning learning and agency have been presented in the discussion of knowledge management. One prevalent notion in the literature is that learning is based on individuals’ voluntary actions and this has now become incompatible with the growing interest in knowledge-management systems. Furthermore, commonly held view of learning as a general process that is independent of the object of learning contradicts the observation that the current need for new knowledge and new competences are caused by ongoing techno-economic changes. Even though the current view acknowledges that individuals and communities have key roles in knowledge creation, this conception defies the idea of the individuals’ and communities’ agency in developing the practices through which they learn. This research therefore presents a new theoretical interpretation of learning and agency based on Cultural-Historical Activity Theory. This approach overcomes the paradoxes in knowledge-management theory and offers means for understanding and analyzing changes in the ways of learning within work communities. This research is also an evaluation of the Competence-Laboratory method which was developed as part of the study as a special application of Developmental Work Research methodology. The research data comprises the videotaped competence-laboratory processes of four front-line work communities in a telecommunications company. The findings reported in the five articles included in this thesis are based on the analyses of this data. The new theoretical interpretation offered here is based on the assessment that the findings reported in the articles represent one of the front lines of the ongoing historical transformation of work-related learning since the research site represents one of the key industries of the new “knowledge society”. The research can be characterized as elaboration of a hypothesis concerning the development of work related learning. According to the new theoretical interpretation, the object of activity is also the object of distributed learning in work communities. The historical socialization of production has increased the number of actors involved in an activity, which has also increased the number of mutual interdependencies as well as the need for communication. Learning practices and organizational systems of learning are historically developed forms of distributed learning mediated by specific forms of division of labor, specific tools, and specific rules. However, the learning practices of the mass production era become increasingly inadequate to accommodate the conditions in the new economy. This was manifested in the front-line work communities in the research site as an aggravating contradiction between the new objects of learning and the prevailing learning practices. The constituent element of this new theoretical interpretation is the idea of a work community’s learning as part of its collaborative mastery of the developing business activity. The development of the business activity is at the same time a practical and an epistemic object for the community. This kind of changing object cannot be mastered by using learning practices designed for the stable conditions of mass production, because learning has to change along the changes in business. According to the model introduced in this thesis, the transformation of learning proceeds through specific stages: predefined learning tasks are first transformed into learning through re-conceptualizing the object of the activity and of the joint learning and then, as the new object becomes stabilized, into the creation of new kinds of learning practices to master the re-defined object of the activity. This transformation of the form of learning is realized through a stepwise expansion of the work community’s agency. To summarize, the conceptual model developed in this study sets the tool-mediated co-development of the subject and the object of learning as the theoretical starting point for developing new, second-generation knowledge management methods. Key words: knowledge management, learning practice, organizational system of learning, agency

Laatutyöhön sitoutumisen edellytykset ammattikorkeakoulussa

The goal of this research was to establish the necessary conditions under which individuals are prepared to commit themselves to quality assurance work in the organisation of a Polytechnic. The conditions were studied using four main concepts: awareness of quality, commitment to the organisation, leadership and work welfare. First, individuals were asked to describe these four concepts. Then, relationships between the concepts were analysed in order to establish the conditions for the commitment of an individual towards quality assurance work (QA). The study group comprised the entire personnel of Helsinki Polytechnic, of which 341 (44.5%) individuals participated. Mixed methods were used as the methodological base. A questionnaire and interviews were used as the research methods. The data from the interviews were used for the validation of the results, as well as for completing the analysis. The results of these interviews and analyses were integrated using the concurrent nested design method. In addition, the questionnaire was used to separately analyse the impressions and meanings of the awareness of quality and leadership, because, according to the pre-understanding, impressions of phenomena expressed in terms of reality have an influence on the commitment to QA. In addition to statistical figures, principal component analysis was used as a description method. For comparisons between groups, one way variance analysis and effect size analysis were used. For explaining the analysis methods, forward regression analysis and structural modelling were applied. As a result of the research it was found that 51% of the conditions necessary for a commitment to QA were explained by an individual’s experience/belief that QA was a method of development, that QA was possible to participate in and that the meaning of quality included both product and process qualities. If analysed separately, other main concepts (commitment to the organisation, leadership and work welfare) played only a small part in explaining an individual’s commitment. In the context of this research, a structural path model of the main concepts was built. In the model, the concepts were interconnected by paths created as a result of a literature search covering the main concepts, as well as a result of an analysis of the empirical material of this thesis work. The path model explained 46% of the necessary conditions under which individuals are prepared to commit themselves to QA. The most important path for achieving a commitment stemmed from product and system quality emanating from the new goals of the Polytechnic, moved through the individual’s experience that QA is a method of the total development of quality and ended in a commitment to QA. The second most important path stemmed from the individual’s experience of belonging to a supportive work community, moved through the supportive value of the job and through affective commitment to the organisation and ended in a commitment to QA. The third path stemmed from an individual’s experiences in participating in QA, moved through collective system quality and through these to the supportive value of the job to affective commitment to the organisation and ended in a commitment to QA. The final path in the path model stemmed from leadership by empowerment, moved through collective system quality, the supportive value of the job and an affective commitment to the organisation, and again, ended in a commitment to QA. As a result of the research, it was found that the individual’s functional department was an important factor in explaining the differences between groups. Therefore, it was found that understanding the processing of part cultures in the organisation is important when developing QA. Likewise, learning-teaching paradigms proved to be a differentiating factor. Individuals thinking according to the humanistic-constructivistic paradigm showed more commitment to QA than technological-rational thinkers. Also, it was proved that the QA training program did not increase commitment, as the path model demonstrated that those who participated in training showed 34% commitment, whereas those who did not showed 55% commitment. As a summary of the results it can be said that the necessary conditions under which individuals are prepared to commit themselves to QA cannot be treated in a reductionistic way. Instead, the conditions must be treated as one totality, with all the main concepts interacting simultaneously. Also, the theoretical framework of quality must include its dynamic aspect, which means the development of the work of the individual and learning through auditing. In addition, this dynamism includes the reflection of the paradigm of the functions of the individual as well as that of all parts of the organisation. It is important to understand and manage the various ways of thinking and the cultural differences produced by the fragmentation of the organisation. Finally, it seems possible that the path model can be generalised for use in any organisation development project where the personnel should be committed.

Heila-tietojärjestelmäprojekti ja sen ongelmat : Tutkimus Helsingin yliopiston henkilöstöhallinnon tietojärjestelmän kehitys- ja käyttöönottotyöstä asiakkaan näkökulmasta

Tutkimuksen tehtävänä oli selvittää Helsingin yliopiston Heila-tietojärjestelmän kehitysprojektin kulkua vuosina 1994-1999. Toisena tutkimustehtävänä oli selvittää minkälaisia ongelmia projektissa oli esiintynyt. Tutkimuksen aineisto oli projektin dokumentaatio, jossa pääaineistona olivat projektin johto- ja projektiryhmien kokouspöytäkirjat, tilanneraportit ja muut määrämuotoiset projektidokumentit. Lisäksi käytettävissä oli muuta aineistoa, kuten Heila-projektia käsitteleviä sähköpostiviestejä ja yleisönosaston kirjoituksia. Tutkimuksessa aineistoa kuvattiin kertomuksellisesti, projektin tapahtumat kirjattiin kertomukseksi kronologisessa järjestyksessä. Aineistoa analysoitiin toisen tutkimustehtävän mukaisesti sisällön analyysillä, ja tästä tuloksena oli projektin ongelmien luokittelu. Lopuksi tarkasteltiin projektin etenemiskertomuksen ja ongelmien luokittelun suhdetta. Kohteena ollut projekti viivästyi aikataulustaan kaikissa vaiheissa: toteutus- ja käyttöönotot viivästyivät useita kuukausia. Projektissa ilmeni resurssipulaa, välillä toimittajan ja välillä asiakkaan eli Helsingin yliopiston puolella. Lisäksi ohjelman sisältöalue oli niin monimutkainen, että se aiheutti vaikeuksia toteutuksessa ja käytössä. Järjestelmän suorituskyky ei vastannut sovittua, käyttöönottojen jälkeen jopa yksinkertainen tallennustoiminto saattoi kestää useita minuutteja, eikä normaaleja työtoimintoja saatu hoidettua. Helsingin yliopisto teki useita kirjallisia huomautuksia ja korvausvaatimuksia toimittajalle. Ongelmat jakautuivat toimintatapoihin liittyviin ongelmiin ja teknisiin ongelmiin. Toimintatapoihin liittyvät ongelmat sisälsivät käyttäjien huomiointiin ja projektin läpivientiin liittyviä ongelmia. Tekniset ongelmat jakautuivat kolmeen alakategoriaan: suorituskyvyn ongelmat, ohjelman ominaisuuksiin liittyvät ongelmat sekä yhteyksiin liittyvät ongelmat. Kukin alakategoria jakautui luokkiin. Projektin etenemistä arvioitiin suhteessa sen toteuttamista ohjanneeseen Helsingin yliopiston yhteistyöprojektien laatuohjeeseen, sekä Niemen (1993) malliin tietojärjestelmäprojektien läpiviennistä. Ongelmien luokittelua verrattiin Niemen (1993) arvioon projektien ongelmista. Projektin onnistumista arvioitiin Saarisen ja Sääksjärven (1992) projektin onnistumisen teorian avulla. Tulosten perusteella on mahdollista tarkastella muita projekteja, ja ongelmaluokitusten perusteella havaita potentiaaliset ongelmat. Siten voidaan parantaa työskentelyolosuhteita ja onnistumisen edellytyksiä tietojärjestelmäprojekteissa. Avainsanat: Tietojärjestelmät, projektityö, ongelmat Keywords: Information systems, project work, problems

Suomalaisten jääkiekkovalmentajien johtamiskäyttäytyminen

Tutkimuksen kohteena olivat jääkiekon valmentajakoulutukseen vuosina 1998 ja 1999 osallistuneet 30 valmentajaa. Valmentajien johtamistoimintaa arvioi yhteensä 245 pelaajaa ja lisäksi valmentajat arvioivat itse omaa johtamistoimintaansa. Menetelmänä käytettiin 360 asteen CPE (Change, Production, Employee)-johtamisarviota. Kuuden faktorin malli nousi tulkinnallisesti tarkoituksenmukaisimmaksi. Faktorit nimettiin seuraavasti: visiointi ja muutos, kontrolli, pelaajien positiivinen huomiointi, reiluus jaoikeudenmukaisuus, kehitys ja toimeenpano ja valmentava yksilöllinen ohjaus. Faktoreiden sisäinen konsistenssi vaihteli välillä .70 ja .80. Pelaajat arvioivat valmennuspäälliköt merkitsevästi valmentajia korkeammalla visiointi ja muutosfaktorilla, pelaajien positiivisessa huomioinnissa sekä kehitys ja toimeenpanofaktorilla. Korkeammin koulutetut arvioitiin myös korkeammallavisiointi ja muutosfaktorilla kuin vähemmän koulutusta saaneet. Jatkotarkastelua varten aineisto klusteroitiin ja klustereiden määräksi valittiin 5. Korkean profiilin valmentajat olivat itsearvioinneissaan varovaisempia, kun taas matalamman profiilin valmentajat olivat taipuvaisia itsensä yliarviointiin. Tulokset näyttäisivät tukevan käsitystä siitä, että johtaminen valmentamisessa on laadullisesti erilaista kuinjohtaminen työelämässä ja että valmentajan johtamistoiminnan arvioimiseen ei voida suoraan soveltaa työelämän tarpeisiin kehitettyjä mittareita. Valmennuskulttuurissa on vähitellen nostamassa päätään muutossuuntautunut ja ihmiskeskeisempi valmennuskulttuuri, jossa pelaajat nähdään enemmän kehityskykyisinä yksilöinä kuin kasvottomana pelaaja-materiaalina. Urheilu ei voi elää tyhjiössä, vaan ulkopuolisen maailman odotukset ja muutospaineet muuttavat väistämättä myös valmennuskulttuuria muun maailman kehityksen tahdissa.

Aika hyvä rehtoriksi : Selviääkö koulun johtamisesta hengissä?

The aim of this study was to describe school leadership on a practical level. By observing the daily behaviour of a principal minute by minute, the study tried to answer the following questions: how did the principals use their time, did they have time to develop their school after participating in the daily life of the school, and how did the previously studied challenges of modern leadership show in their practical work? Five principals in different areas of Helsinki were observed – two women and three men. The principals were chosen at random from three educational conferences. The main hypothesis of this research was that the work of the principal consists of solving daily problems and routines concerning the pupils, teachers and other interest groups and writing all kinds of bureaucratic reports. This means that the school and its principal do not have enough resources to give to a visionary development of teaching and learning – in other words pedagogical leading – even though every principal has the best knowledge about his or her own school’s status quo and the needs for development revealed by this status quo. The research material was gathered by applying the Peer-Assisted Leadership method. The researcher shadowed each principal for four days for three hours at a time. After each shadowing period, any unclear situations were clarified with a short interview. After all the shadowing periods, the principals participated in a semi-structured interview that covered the themes emerging from the shadowing material. In addition to this, the principals evaluated their own leading with a self-assessment questionnaire. The results gathered from the shadowing material showed that the actions of the principals were focused on bureaucratic work. The principals spent most of their time in the office (more than 50%). In the office they were sitting mainly by the computer. They also spent a significant mount of time in the office meeting teachers and occasional visitors. The time spent building networks was relatively short, although the principals considered it as an important domain of leadership according to their interviews. After the classification of the shadowing material, the activities of the principals were divided according to certain factors affecting them. The underlying factors were quality management, daily life management, strategic thinking and emotional intelligence. Through these factors the research showed that coping with the daily life of the school took about 40% of the principals’ time. Activities connected with emotional intelligence could be observed over 30% and activities which required strategic thinking were observed over 20% of the time. The activities which according to the criteria of the research consisted of quality management took only 8% of the principals’ time. This result was congruent with previous studies showing that the work of school leaders is focused on something other than developing the quality of teaching and learning. Keywords: distributed leadership, building community, network building, interaction, emotional intelligence, strategy, quality management

Kohti ulkorajoja : Lukion toimintakulttuurikuvaus ohjauksen ja johtamisen näkökulmasta

The aim of this qualitative study is to chart the operational context of the upper-secondary school principals and the historical, cultural and structural factors that steer their day-to-day work. The concepts regarding the study environment and operational culture are defined and analysed in terms of how they are interrelated. Furthermore it is explained why the upper-secondary schools must describe their operational culture within the curriculum. The study also aims to connect the description of the operational culture with the operational system of the upper-secondary school and to analyse the descriptions of the five upper-secondary schools in relation to the commitment to developing a study environment conducive to learning and participation, as well as conducive to supporting interaction. Interview data is used to provide the background for the description of the operational culture and to particularise the results of the analysis. According to the theory used in this study, the steering sources of the day-to-day work of the upper-secondary school are the rules system of the state, the municipality, the curriculum, and on the level of the upper-secondary school administration. The research data consist of the literature concerning the steering, steering forms and the principals professional picture in general terms, from 1950 to the present, and the steering texts concerning the educational environment and operational culture. Furthermore the research data include five descriptions of the operational culture concerning the upper-secondary school, the action reports and student guides. The methods of analysis include the level model and content analysis. The first is a part of the theory used in this study. For the purpose of content analysis, moreover, classifying grounds are established on the basis of theoretical and empirical research data. A result of this study is that, from the perspective of steering, the function of describing the operational culture is clearly linked to the evaluation supporting the goals and the vision of a learning organization. From an administrative point of view, a description is a problem-solving strategy and an instrument of evaluation. The study environment is a structural context in and through which the actors of the school create, change and renew the elements of the structure rooted in the context; this structure is their historically and culturally mediated way of thinking and acting. The initial situation and orientation of the students affect the emphasis of the operational culture descriptions; principals also have their own personal style of leadership. Key words: source of steering, educational environment, operational culture, self-evaluation, learning organisation

Sleep deprivation and brain energy metabolism : in vivo studies in rats and humans

Sleep deprivation leads to increased subsequent sleep length and depth and to deficits in cognitive performance in humans. In animals extreme sleep deprivation is eventually fatal. The cellular and molecular mechanisms causing the symptoms of sleep deprivation are unclear. This thesis was inspired by the hypothesis that during wakefulness brain energy stores would be depleted, and they would be replenished during sleep. The aim of this thesis was to elucidate the energy metabolic processes taking place in the brain during sleep deprivation. Endogenous brain energy metabolite levels were assessed in vivo in rats and in humans in four separate studies (Studies I-IV). In the first part (Study I) the effects of local energy depletion on brain energy metabolism and sleep were studied in rats with the use of in vivo microdialysis combined with high performance liquid chromatography. Energy depletion induced by 2,4-dinitrophenol infusion into the basal forebrain was comparable to the effects of sleep deprivation: both increased extracellular concentrations of adenosine, lactate, and pyruvate, and elevated subsequent sleep. This result supports the hypothesis of a connection between brain energy metabolism and sleep. The second part involved healthy human subjects (Studies II-IV). Study II aimed to assess the feasibility of applying proton magnetic resonance spectroscopy (1H MRS) to study brain lactate levels during cognitive stimulation. Cognitive stimulation induced an increase in lactate levels in the left inferior frontal gyrus, showing that metabolic imaging of neuronal activity related to cognition is possible with 1H MRS. Study III examined the effects of sleep deprivation and aging on the brain lactate response to cognitive stimulation. No physiologic, cognitive stimulation-induced lactate response appeared in the sleep-deprived and in the aging subjects, which can be interpreted as a sign of malfunctioning of brain energy metabolism. This malfunctioning may contribute to the functional impairment of the frontal cortex both during aging and sleep deprivation. Finally (Study IV), 1H MRS major metabolite levels in the occipital cortex were assessed during sleep deprivation and during photic stimulation. N-acetyl-aspartate (NAA/H2O) decreased during sleep deprivation, supporting the hypothesis of sleep deprivation-induced disturbance in brain energy metabolism. Choline containing compounds (Cho/H2O) decreased during sleep deprivation and recovered to alert levels during photic stimulation, pointing towards changes in membrane metabolism, and giving support to earlier observations of altered brain response to stimulation during sleep deprivation. Based on these findings, it can be concluded that sleep deprivation alters brain energy metabolism. However, the effects of sleep deprivation on brain energy metabolism may vary from one brain area to another. Although an effect of sleep deprivation might not in all cases be detectable in the non-stimulated baseline state, a challenge imposed by cognitive or photic stimulation can reveal significant changes. It can be hypothesized that brain energy metabolism during sleep deprivation is more vulnerable than in the alert state. Changes in brain energy metabolism may participate in the homeostatic regulation of sleep and contribute to the deficits in cognitive performance during sleep deprivation.

The molecular basis of Marinesco-Sjögren syndrome

Marinesco-Sjögren syndrome (MSS) is a rare autosomal recessive neurodegenerative disorder characterized by cerebellar ataxia due to cerebellar cortical atrophy, infantile- or childhood-onset bilateral cataracts, progressive myopathy, and mild to severe mental retardation. Additional features include hypergonadotropic hypogonadism, various skeletal abnormalities, short stature, and strabismus. The neuroradiologic hallmarks are hypoplasia of both the vermis and cerebellar hemispheres. The histopathologic findings include severe cerebellar atrophy and loss of Purkinje and granule cells. The common pathologic findings in muscle biopsy are variation in muscle fiber size, atrophic fibers, fatty replacement, and rimmed vacuole formation. The presence of marked cerebellar atrophy with myopathy distinguishes MSS from another rare syndrome, the congenital cataracts, facial dysmorphism, and neuropathy syndrome (CCFDN). Previously, work by others had resulted in the identification of an MSS locus on chromosome 5q31. A subtype of MSS with myoglobinuria and neuropathy had been linked to the CCFDN locus on chromosome 18qter, at which mutations in the CTDP1 gene had been identified. We confirmed linkage to the previously identified locus on chromosome 5q31 in two Finnish families with eight affected individuals, reduced the critical region by fine-mapping, and identified SIL1 as a gene underlying MSS. We found a common homozygous founder mutation in all Finnish patients. The same mutation was also present in patient samples from Norway and Sweden. Altogether, we identified eight mutations in SIL1, including nonsense, frameshift, splice site alterations, and one missense mutation. SIL1 encodes a nucleotide exchange factor for the endoplasmic reticulum (ER) resident heat-shock protein 70 chaperone GRP78. GRP78 functions in protein synthesis and quality control of the newly synthesized polypeptides. It senses and responds to stressful cellular conditions. We showed that in mice, SIL1 and GRP78 show highly similar spatial and temporal tissue expression in developing and mature brain, eye, and muscle. Studying endogenous proteins in mouse primary hippocampal neurons, we found that SIL1 and GRP78 colocalize and that SIL1 localizes to the ER. We studied the subcellular localization of two mutant proteins, a missense mutant found in two patients and an artificial mutant lacking the ER retrieval signal, and found that both mutant proteins formed aggregates within the ER. Well in line with our findings and the clinical features of MSS, recent work by Zhao et al. showed that a truncation of SIL1 causes ataxia and cerebellar Purkinje cell loss in the naturally occurring woozy mutant mouse. Prior to Purkinje cell degeneration, the unfolded protein response is initiated and abnormal protein accumulations are present. MSS thus joins the group of protein misfolding and accumulation diseases. These findings highlight the importance of SIL1 and the role of the ER in neuronal function and survival. The results presented in this thesis provide tools for the molecular genetic diagnostics of MSS and give a basis for future studies on the molecular pathogenesis of MSS. Understanding the mechanisms behind this pleiotropic syndrome may provide insights into more common forms of ataxia, myopathy, and neurodegeneration.
