Supplier segmentation and development in project business

The purpose of this study was to expand the applicability of supplier segmentation and development approaches to the project-driven construction industry. These practices are less exploited and not well documented in this operational environment compared to the process-centric manufacturing industry. At first, portfolio models to supply base segmentation and various supplier development efforts were investigated in literature review. A step-wise framework was structured for the empirical research. The empirical study employed multiple research methods in three case studies in a large Finnish construction company. The first study categorized the construction item classes into the purchasing portfolio and positioned suppliers to the power matrix by investigating buyer-supplier relations. Using statistical tests, the study also identified factors that affect suppliers’ performance. The final case study identified improvement areas of the interface between a main contractor and one if its largest suppliers. The final results indicate that only by assessing the supply base in a holistic manner and the power circumstances in it, buyers comprehend how to best establish appropriate supplier development strategies in the project environment.

Sisäisen logistiikan prosessien ja materiaalivirtojen tehostaminen

Työn tavoitteena on löytää kohdeyrityksen sisäisen logistiikan prosessien ja materiaalivirtojen tehostamiskohteita. Sisäisen logistiikan ja materiaalienohjauksen toimivuutta halutaan tutkittavan lähtötiedoksi prosessien ja materiaalivirtojen parantamiselle. Materiaalivirtojen tutkimisella saadaan selville tutkimuksen aikana suoritettavan kehitysprojektin aiheuttamat muutokset. Tutkimuksen aikana kehitetään kustannustyökalu, jolla voidaan määrittää materiaaliensiirroista aiheutuvia kustannuksia. Tutkimus suoritettiin käyttäen sekä kvantitatiivisia että kvalitatiivisia tutkimusmenetelmiä. Haastattelut ja keskustelut antoivat lähtötiedot materiaalivirtojen tutkimiselle, jonka vuoksi ne tukevat toinen toisiaan. Taustatiedoksi syvennytään kirjallisuudessa ilmenneisiin ohjeisiin prosessien ja materiaalivirtojen analysoimisesta, mittareista sekä kehitettävän kustannustyökalun kannalta toimintolaskennan menetelmistä. Tutkimuksen tuloksena pystyttiin havaitsemaan prosessien toimintoihin liityviä haasteita sekä turhia materiaalivirtoja. Materiaalivirta-analyysillä pystyttiin arvioimaan materiaalivirtojen merkitystä sekä kehitysprojektin aiheuttamien muutoksien luomia vaatimuksia. Lisäksi materiaalivirta-analyysin pohjalta pystyttiin muodostamaan skenaarioita materiaalivirtojen tehostamiseksi.

Perehdyttäminen osana strategista osaamisen kehittämistä - Uusien esimiesten perehdyttäminen kuntaorganisaatiossa

Perehdyttäminen ja osaamisen kehittäminen ovat koko ajan entistä keskeisempiä tekijöitä yritysten menestymisessä entistä nopeammin muuttuvassa maailmassa. Tässä Pro gradu-tutkielmassa tutkitaan uusien esimiesten perehdyttämistä. Tavoitteena on selvittää esimiesten perehdyttämisen toteuttaminen, keskeiset kehittämiskohteet sekä henkilöstöhallinnossa kartoitettujen esimiestyön osaamisvaatimusten näkyminen kohdeorganisaation perehdytysprosessissa. Tutkimuksessa tarkastellaan perehdyttämisen ja osaamisen kehittämisen tieteellistä viitekehystä. Tutkimuksessa on yhdistetty laadullisen ja määrällisen tutkimuksen menetelmiä. Tutkimus on toteutettu sähköisenä lomakekyselynä. Uusien esimiesten perehdyttämisen toteuttamisessa oli havaittavissa eroja kohdeorganisaation uusien esimiesten välillä. Pääasiallisena perehdyttäjänä oli toiminut oma esimies. Suuri osa esimiehistä oli melko tyytyväisiä omaan perehdyttämiseensä ja heillä oli positiivisia kehittymisnäkymiä osaamisensa kasvamisesta seuraavan vuoden aikana. Keskeisinä kehittämiskohteina esille nousivat epäyhteneväisyydet perehdyttämisessä, joidenkin uusien esimiesten yksin jääminen sekä perehdyttämisen tukimateriaalien tarve. Esimiestyön osaamisvaatimuksia ei ollut tuotu aktiivisesti esiin prosessin aikana.

Ilmastonmuutosteknologiat maailman patenttijärjestelmissä: Case autoteollisuus

Tässä työssä tarkastellaan kahden kansainvälisen patenttiluokitusjärjestelmän vihreiden teknologioiden luokitusjärjestelmiä autoteollisuudessa. Työn tarkoitus on tutkia, kuinka paljon vihreän teknologian patenttianalyysin tulokset eroavat toisistaan, jos tutkimuksissa käytetään eri patenttien luokitusjärjestelmiä. Vanhempi järjestelmä, International Patent Classification, on asemansa vakiinnuttanut kansainvälinen patenttienluokitusjärjestelmä. Vasta viime vuosina käyttöön otettu Cooperative Patent Classification on Euroopan ja Yhdysvaltojen patenttijärjestöjen kehittämä patenttien luokitusjärjestelmä. Tutkimusmenetelmissä hyödynnetään patenttianalyysia ja joukko-oppia. Tutkimuksessa vihreiden teknologioiden luokittelumenetelmien vertailukohteille saatiin määrällisesti samankaltaiset tulokset, mutta niiden sisältämät patentit eivät olleet pääsäännöllisesti samoja. Työssä tarkastellaan myös Toyotan, Daimlerin ja Fordin vihreiden autoteknologiapolkujen kehitystä. Varsinkin Toyota ja Daimler tulevat yhä enemmän panostamaan sähkö- ja hybridiautoihin verrattuna polttomoottoriautoihin.

Metsäkoneiden panssareiden ja pohjan luukkujen laadun kehittäminen

Tutkimuksen tarkoituksena oli selvittää, mitkä asiat tutkimuksen toimeksiantavan yrityksen, John Deere Forestry Oy:n metsäkoneiden panssareiden ja luukkujen kanssa työskentelevä henkilöstö kokee oleellisimmiksi pohjan suojien asennettavuuden, käytettävyyden, kestävyyden ja laadun kehittämisessä. Tutkimuksella haluttiin myös selvittää, mitä hyödynnettävää tietoa yrityksen sisältä jo löytyy, mitä hiljaista tietoa henkilöstöllä on ja miten tätä kaikkea voidaan hyödyntää jatkossa suunnittelun tukena. Pääasiallisina tutkimusmenetelminä käytettiin strukturoitua kyselytutkimusta, toimeksiantavan yrityksen sekä kilpailijoiden rakenneratkaisujen tarkastelua sekä lujuuslaskentaa. Kyselytutkimuksen aineisto kerättiin loppukesästä 2014. Otanta koostui 149:stä eri toimipaikkojen työntekijästä. Aineisto käsiteltiin pääasiassa kvantitatiivisesti käyttämällä ristiintaulukointia. Kyselytutkimuksen tulosten perusteella syvennyttiin tarkastelemaan pohjan suojausta myös koneteknillisellä lähestymistavalla. Tarkastelun kohteeksi valitulle panssarille tehtiin lujuuslaskentoja kyselyn vastausten varmentamiseksi ja ongelmien tarkentamiseksi, parannusehdotuksien tueksi. Aihetta tarkasteltiin asennusergonomian, työturvallisuuden ja vaurioitumismekanismien valossa. Tulosten analysoinnin yhteydessä esitettiin ratkaisuehdotuksia yleisimpiin ongelmiin laadun kehittämiseksi. Keskeisimmät ratkaisuehdotukset liittyvät panssareiden rakenteellisen stabiiliuden parantamiseen. Käytännön toimenpide-esityksinä esimerkiksi jäykisteet, tuennat, materiaalivalinnat, uudelleenmuotoilu, apuasennustyökalut, turvavarustelut ja avautumissuunnat olisivat huomion arvoisia asioita. Tutkimuksessa kerätty tieto kootaan sovellettavaksi käytäntöön laadun kehittämiseksi tekemällä toimeksiantavalle yritykselle metsäkoneiden panssareiden ja pohjan luukkujen suunnitteluohje. Tällä pyritään jatkossa parantamaan kilpailukykyä.

Hoitokuluanalyysi Suomen yksityisen sektorin työeläkejärjestelmästä

Tämän pro gradu -tutkielman tavoitteena on tutkia Suomen työeläkevakuutusyhtiöiden työeläkevakuutusmaksun hoitokustannusosalla katettavia liikekuluja ja muodostaa analyysi Suomen työeläkevakuutusjärjestelmän liikekulujen kehittymisestä ja tehokkuuden tasosta. Tehokkuusnäkökulman lisäksi tarkastellaan työeläkejärjestelmän kilpailuolosuhteita. Tutkimusta motivoi työeläkealalle ajankohtainen asia, joka liittyy yhtiökohtaisen hinnoittelumallin mahdolliseen käyttöönottoon, jota parhaillaan suunnitellaan työeläkealan tehokkuuden ja kilpailullisuuden lisäämiseksi. Yhtiökohtaisessa hinnoittelumallissa työeläkeyhtiö voisi itsenäisesti vaikuttaa työeläkevakuutuksen hintaan hoitokustannusosan kautta, joka määräytyisi pitkälti sen mukaan kuinka tehokkaasti yhtiö pystyy toimintansa järjestämään. Empiirinen tutkimus on toteutettu kvalitatiivisena tapaustutkimuksena, jossa kuitenkin empiirinen analyysi perustuu kvantitatiiviseen aineistoon ja aineistoa on käsitelty kvantitatiivisen tutkimuksen menetelmin. Pääasiallisina tutkimusotteina on käytetty taulukointia ja erinäisten muuttujien välistä korrelaatiota. Tuloksien suhteen on käytetty aineistolähtöistä induktiivista päättelyä. Tutkimuksessa on tutkittu seitsemän yksityisen sektorin työeläkeyhtiön liikekuluja vuosilta 2006–2013. Tutkimustuloksien mukaan järjestelmätasolla tarkasteltuna työeläkeyhtiöiden toiminta on tehokasta, joskin yksittäisten yhtiöiden välillä on suuriakin tehokkuuseroja. Vakuutusten ja korvaustoiminnan hoito ovat suurimmat kustannusten aiheuttajat. Työeläkemarkkinat ovat hyvin keskittyneet ja muistuttavat enemmänkin oligopolisia markkinoita kuin täydellisen kilpailun markkinoita.

Sähköpostista sosiaaliseen mediaan - sosiaalisen median strategia muoviteollisuusalan yritykselle

Sosiaalinen media on muuttanut markkinointia vuorovaikutteisuudella, avoimuudella ja läpinäkyvyydellä. Siksi yritysten kannattaa miettiä kuinka ja miksi lähteä mukaan sosiaaliseen mediaan. Tutkimusta asiasta on rajallisesti ja siksi tässä työssä rakennetaan sosiaalisen media strategia muoviteollisuusalan yritykselle. Työn empiirisessä osuudessa sosiaalisen median strategisia tavoitteita kysyttiin Uponorin johdolta sähköpostikyselyllä. Tulokset analysoitiin kvalitatiivisesti. Lisäksi kartoitettiin Uponorin henkilökunnalle tehdyn verkkopohjaisen lähtötila-analyysin avulla sosiaalisen median käyttöönottoa edistäviä ja estäviä tekijöitä yrityksissä. Aineisto analysoitiin kvantitatiivisin menetelmin. Tulosten perusteella myönteinen suhtautuminen voi edistää sosiaalisen median käyttöönottoa yrityksissä. Toisaalta tutkimuksessa ei voitu osoittaa, että yrityskulttuuriset tekijät estäisivät sosiaalisen median käyttöönottoa. Sosiaalisen median strategia rakennettiin teorian ja kyselyiden tulosten perusteella. Sosiaalisen median käyttö yrityksissä lisääntyy, joten jatkotutkimusta tarvitaan sosiaalisen median hyödyntämisestä yrityskontekstissa myös ulkoisten sidosryhmien osalta.

Hankinnan prosessien systemaattinen kehittäminen

Tämän pro gradu -tutkielman tavoitteena oli standardoida ja kehittää hankinnan prosesseja systemaattisesti. Prosessien standardoiminen edesauttaa organisaation itseohjautuvuutta ja parantaa organisaation kyvykkyyttä. Tämä tutkielma tuottaa uutta tutkimustietoa tutkimusaukkoon hankinnan prosessien systemaattisesta kehittämisestä. Tutkielman teoriaosassa käsitellään prosessiajattelua, ISO 9001 standardin vaikutusta hankintatoimintaan, tunnistetaan hankinnan prosesseja ja esitetään erilaisia hankinnan prosesseihin soveltuvia LEAN Six Sigma kehitystyökaluja. Tutkielman empiirinen osio on toteutettu toimeksiantona suurelle teollisuusyritykselle. Tämän tutkielman empiirisessä osiossa on yhdistelty kvalitatiiviselle ja kvantitatiiviselle tutkimukselle ominaisia tutkimusmetodologioita. Tutkimusmetodologioiden yhdisteleminen tuottaa lisäarvoa tutkielman toteutukselle ja parantaa työn luotettavuutta. Tässä tutkielmassa käytetyt tutkimusmenetelmät koostuvat kvantitatiiviselle tutkimukselle ominaisesta kyselystä hankinnan prosessien nykytilan selvittämiseksi sekä kvalitatiivisen tutkimuksen tutkimusmenetelmille ominaisesta tapaustutkimuksesta. Kyselyn avulla muodostettiin analyysi hankinnan prosessien nykytilasta, jonka pohjalta toimeksiantajayritykselle ehdotettiin kehitettäviä hankinnan prosesseja. Lopulliseksi kehityskohteeksi valittu prosessi määriteltiin aivoriihessä kerätyn tiedon perusteella kehityspotentiaalin esille tuovasta nelikentästä. Kehitettävä prosessi asemoitui samalla tapaustutkimuksella tutkittavaksi tapaukseksi. Kehitettäväksi prosessiksi valittiin saapuvan tavaran vastaanotto ja visuaalinen tarkastaminen. Prosessia kehitettiin mallintamalla ja LEAN Six Sigma menetelmiä hyödyntäen. Prosessimallinnuksen sekä LEAN Six Sigma menetelmien tueksi kerättiin tietoa aivoriihistä ja teemahaastatteluista. Tutkielman tuloksena toimeksiantajayritys sai kokonaiskuvan hankinnan prosessien nykytilasta, kehitetyn tavoiteprosessin ja työohjeen saapuvan tavaran vastaanotolle ja visuaaliselle tarkastukselle sekä jatkossa hankinnan prosessien standardoimista ja kehittämistä helpottavan hankinnan prosessin systemaattisen kehittämismallin. Hankinnan prosessin systemaattinen kehittämismalli on uutta tutkimustietoa, joka asemoituu hankinnan prosessien kehittämisen tutkimusaukkoon. Hankinnan prosessin systemaattista kehittämismallia ei tämän tutkielman pohjalta voida yleistää, koska tutkielma on toteutettu toimeksiantajayrityksen lähtökohdista. Johtopäätöksenä voidaan todeta, että toimeksiantajayritys, muut organisaatiot sekä tutkimuskenttä tarvitsevat lisää tietoa hankinnan prosessien kehittämisestä. Hankinnan prosessien kehittämistä tulisi tutkia enemmän ja erityisesti tässä tutkielmassa esitettyä kehittämismallia tulisi jatkossa testata niin, että kehittämismallin toimivuus voitaisiin yleistää.

Solubilization of human erythrocyte membranes by ASB detergents

Understanding the membrane solubilization process and finding effective solubilizing agents are crucial challenges in biochemical research. Here we report results on the interaction of the novel linear alkylamido propyl dimethyl amino propanosulfonate detergents, ASB-14 and ASB-16, with human erythrocyte membranes. An estimation of the critical micelle concentration of these zwitterionic detergents (ASB-14 = 100 µM and ASB-16 = 10 µM) was obtained using electron paramagnetic resonance. The amount of proteins and cholesterol solubilized from erythrocytes by these detergents was then determined. The hemolytic activities of the ASB detergents were assayed and the detergent/lipid molar ratios for the onset of hemolysis (Re sat) and total lysis (Re sol) were calculated, allowing the determination of the membrane binding constants (Kb). ASB-14 presented lower membrane affinity (Kb = 7050 M-1) than ASB-16 (Kb = 15610 M-1). The amount of proteins and cholesterol solubilized by both ASB detergents was higher while Re sat values (0.22 and 0.08 detergent/lipid for ASB-14 and ASB-16, respectively) were smaller than those observed with the classic detergents CHAPS and Triton X-100. These results reveal that, besides their well-known use as membrane protein solubilizers to enhance the resolution of two dimensional electrophoresis/mass spectrometry, ASB-14 and ASB-16 are strong hemolytic agents. We propose that the physicochemical properties of ASB detergents determine their membrane disruption efficiency and can help to explain the improvement in the solubilization of membrane proteins, as reported in the literature.

Defining Sales and Operations Planning Process in an Environmental Management Company

Sales and operations research publications have increased significantly in the last decades. The concept of sales and operations planning (S&OP) has gained increased recognition and has been put forward as the area within Supply Chain Management (SCM). Development of S&OP is based on the need for determining future actions, both for sales and operations, since off-shoring, outsourcing, complex supply chains and extended lead times make challenges for responding to changes in the marketplace when they occur. Order intake of the case company has grown rapidly during the last years. Along with the growth, new challenges considering data management and information flow have arisen due to increasing customer orders. To manage these challenges, case company has implemented S&OP process, though initial process is in early stage and due to this, the process is not managing the increased customer orders adequately. Thesis objective is to explore extensively the S&OP process content of the case company and give further recommendations. Objectives are categorized into six different groups, to clarify the purpose of this thesis. Qualitative research methods used are active participant observation, qualitative interviews, enquiry, education, and a workshop. It is notable that demand planning was felt as cumbersome, so it is typically the biggest challenge in S&OP process. More proactive the sales forecasting can be, more expanded the time horizon of operational planning will turn out. S&OP process is 60 percent change management, 30 percent process development and 10 percent technology. The change management and continuous improvement can sometimes be arduous and set as secondary. It is important that different people are required to improve the process and the process is constantly evaluated. As well as, process governance is substantially in a central role and it has to be managed consciously. Generally, S&OP process was seen important and all the stakeholders were committed to the process. Particular sections were experienced more important than others, depending on the stakeholders’ point of views. Recommendations to objective groups are evaluated by the achievable benefit and resource requirement. The urgent and easily implemented improvement recommendations should be executed firstly. Next steps are to develop more coherent process structure and refine cost awareness. Afterwards demand planning, supply planning, and reporting should be developed more profoundly. For last, information technology system should be implemented to support the process phases.

Cross-border transmission capacity development – Experiences from the Nordic electricity markets

The liberalisation of the wholesale electricity markets has been considered an efficient way to organise the markets. In Europe, the target is to liberalise and integrate the common European electricity markets. However, insufficient transmission capacity between the market areas hampers the integration, and therefore, new investments are required. Again, massive transmission capacity investments are not usually easy to carry through. This doctoral dissertation aims at elaborating on critical determinants required to deliver the necessary transmission capacity investments. The Nordic electricity market is used as an illustrative example. This study suggests that changes in the governance structure have affected the delivery of Nordic cross-border investments. In addition, the impacts of not fully delivered investments are studied in this doctoral dissertation. An insufficient transmission network can degrade the market uniformity and may also cause a need to split the market into smaller submarkets. This may have financial impacts on market actors when the targeted efficient sharing of resources is not met and even encourage gaming. The research methods applied in this doctoral dissertation are mainly empirical ranging from a Delphi study to case studies and numerical calculations.

FUTURES OF FINNISH FOOD SYSTEM BY 2050. The perspective of resilience

Modern food systems face complex global challenges such as climate change, resource scarcities, population growth, concentration and globalization. It is not possible to forecast how all these challenges will affect food systems, but futures research methods provide possibilities to enable better understanding of possible futures and that way increases futures awareness. In this thesis, the two-round online Delphi method was utilized to research experts’ opinions about the present and the future resilience of the Finnish food system up to 2050. The first round questionnaire was constructed based on the resilience indicators developed for agroecosystems. Sub-systems in the study were primary production (main focus), food industry, retail and consumption. Based on the results from the first round, the future images were constructed for primary production and food industry sub-sections. The second round asked experts’ opinion about the future images’ probability and desirability. In addition, panarchy scenarios were constructed by using the adaptive cycle and panarchy frameworks. Furthermore, a new approach to general resilience indicators was developed combining “categories” of the social ecological systems (structure, behaviors and governance) and general resilience parameters (tightness of feedbacks, modularity, diversity, the amount of change a system can withstand, capacity of learning and self- organizing behavior). The results indicate that there are strengths in the Finnish food system for building resilience. According to experts organic farms and larger farms are perceived as socially self-organized, which can promote innovations and new experimentations for adaptation to changing circumstances. In addition, organic farms are currently seen as the most ecologically self-regulated farms. There are also weaknesses in the Finnish food system restricting resilience building. It is important to reach optimal redundancy, in which efficiency and resilience are in balance. In the whole food system, retail sector will probably face the most dramatic changes in the future, especially, when panarchy scenarios and the future images are reflected. The profitability of farms is and will be a critical cornerstone of the overall resilience in primary production. All in all, the food system experts have very positive views concerning the resilience development of the Finnish food system in the future. Sometimes small and local is beautiful, sometimes large and international is more resilient. However, when probabilities and desirability of the future images were questioned, there were significant deviations. It appears that experts do not always believe desirable futures to materialize.

CORPORATE GRASSROOTS LOBBYING IN THE EUROPEAN UNION

The European Union has gone through significant changes in the past 20 years. The importance of public opinion in politics has increased and the new technologies are empowering the wider public to express its opinions. The purpose of this study is to explore how corporations use the tactic of grassroots lobbying in the European Union environment. The research objectives were addressed through qualitative research methods. Six expert interviews were conducted to find new perspectives and to deepen the understanding of the research objectives. Following the data collection, the research material was transcribed and analysed. In the analysis, the data was organized based on concepts and themes found from the literature review. The empirical findings on grassroots lobbying in the EU were presented. It was found that when a company is selecting grassroots lobbying tactic, the familiarity of the tactic, organizational culture, financial resources and amount of stakeholders seem to have an impact to the selection. The issues that are successfully lobbied through the grassroots-lobbying tactic were seen to be those, which have high and direct impact on lives of people, arouse strong feelings and are not very complex. Furthermore, when deciding on the timing of a campaign, in the EU it was found that a company should take into account the long policy process and limited capabilities to mobilise people. Targeting the object of the campaign and selecting the channels used in a grassroots- lobbying campaign were seen to be in function of identifying the key decision-makers on the issue. The decisions of who to mobilise and the mobilisation channels were considered to be dependant on who the campaign is trying to influence. Also, it was found that when the implementing a grassroots lobbying campaign in the EU environment, the special features such as multiple cultures and languages should be taken into account. This study has provided novel practical insights for corporate grassroots lobbying in the EU environment and furthermore successfully contributed to the academic research in the field.

Socially shared metacognitive regulation during collaborative learning processes in student dyads and small groups

Traditionally metacognition has been theorised, methodologically studied and empirically tested from the standpoint mainly of individuals and their learning contexts. In this dissertation the emergence of metacognition is analysed more broadly. The aim of the dissertation was to explore socially shared metacognitive regulation (SSMR) as part of collaborative learning processes taking place in student dyads and small learning groups. The specific aims were to extend the concept of individual metacognition to SSMR, to develop methods to capture and analyse SSMR and to validate the usefulness of the concept of SSMR in two different learning contexts; in face-to-face student dyads solving mathematical word problems and also in small groups taking part in inquiry-based science learning in an asynchronous computer-supported collaborative learning (CSCL) environment. This dissertation is comprised of four studies. In Study I, the main aim was to explore if and how metacognition emerges during problem solving in student dyads and then to develop a method for analysing the social level of awareness, monitoring, and regulatory processes emerging during the problem solving. Two dyads comprised of 10-year-old students who were high-achieving especially in mathematical word problem solving and reading comprehension were involved in the study. An in-depth case analysis was conducted. Data consisted of over 16 (30–45 minutes) videotaped and transcribed face-to-face sessions. The dyads solved altogether 151 mathematical word problems of different difficulty levels in a game-format learning environment. The interaction flowchart was used in the analysis to uncover socially shared metacognition. Interviews (also stimulated recall interviews) were conducted in order to obtain further information about socially shared metacognition. The findings showed the emergence of metacognition in a collaborative learning context in a way that cannot solely be explained by individual conception. The concept of socially-shared metacognition (SSMR) was proposed. The results highlighted the emergence of socially shared metacognition specifically in problems where dyads encountered challenges. Small verbal and nonverbal signals between students also triggered the emergence of socially shared metacognition. Additionally, one dyad implemented a system whereby they shared metacognitive regulation based on their strengths in learning. Overall, the findings suggested that in order to discover patterns of socially shared metacognition, it is important to investigate metacognition over time. However, it was concluded that more research on socially shared metacognition, from larger data sets, is needed. These findings formed the basis of the second study. In Study II, the specific aim was to investigate whether socially shared metacognition can be reliably identified from a large dataset of collaborative face-to-face mathematical word problem solving sessions by student dyads. We specifically examined different difficulty levels of tasks as well as the function and focus of socially shared metacognition. Furthermore, the presence of observable metacognitive experiences at the beginning of socially shared metacognition was explored. Four dyads participated in the study. Each dyad was comprised of high-achieving 10-year-old students, ranked in the top 11% of their fourth grade peers (n=393). Dyads were from the same data set as in Study I. The dyads worked face-to-face in a computer-supported, game-format learning environment. Problem-solving processes for 251 tasks at three difficulty levels taking place during 56 (30–45 minutes) lessons were video-taped and analysed. Baseline data for this study were 14 675 turns of transcribed verbal and nonverbal behaviours observed in four study dyads. The micro-level analysis illustrated how participants moved between different channels of communication (individual and interpersonal). The unit of analysis was a set of turns, referred to as an ‘episode’. The results indicated that socially shared metacognition and its function and focus, as well as the appearance of metacognitive experiences can be defined in a reliable way from a larger data set by independent coders. A comparison of the different difficulty levels of the problems suggested that in order to trigger socially shared metacognition in small groups, the problems should be more difficult, as opposed to moderately difficult or easy. Although socially shared metacognition was found in collaborative face-to-face problem solving among high-achieving student dyads, more research is needed in different contexts. This consideration created the basis of the research on socially shared metacognition in Studies III and IV. In Study III, the aim was to expand the research on SSMR from face-to-face mathematical problem solving in student dyads to inquiry-based science learning among small groups in an asynchronous computer-supported collaborative learning (CSCL) environment. The specific aims were to investigate SSMR’s evolvement and functions in a CSCL environment and to explore how SSMR emerges at different phases of the inquiry process. Finally, individual student participation in SSMR during the process was studied. An in-depth explanatory case study of one small group of four girls aged 12 years was carried out. The girls attended a class that has an entrance examination and conducts a language-enriched curriculum. The small group solved complex science problems in an asynchronous CSCL environment, participating in research-like processes of inquiry during 22 lessons (á 45–minute). Students’ network discussion were recorded in written notes (N=640) which were used as study data. A set of notes, referred to here as a ‘thread’, was used as the unit of analysis. The inter-coder agreement was regarded as substantial. The results indicated that SSMR emerges in a small group’s asynchronous CSCL inquiry process in the science domain. Hence, the results of Study III were in line with the previous Study I and Study II and revealed that metacognition cannot be reduced to the individual level alone. The findings also confirm that SSMR should be examined as a process, since SSMR can evolve during different phases and that different SSMR threads overlapped and intertwined. Although the classification of SSMR’s functions was applicable in the context of CSCL in a small group, the dominant function was different in the asynchronous CSCL inquiry in the small group in a science activity than in mathematical word problem solving among student dyads (Study II). Further, the use of different analytical methods provided complementary findings about students’ participation in SSMR. The findings suggest that it is not enough to code just a single written note or simply to examine who has the largest number of notes in the SSMR thread but also to examine the connections between the notes. As the findings of the present study are based on an in-depth analysis of a single small group, further cases were examined in Study IV, as well as looking at the SSMR’s focus, which was also studied in a face-to-face context. In Study IV, the general aim was to investigate the emergence of SSMR with a larger data set from an asynchronous CSCL inquiry process in small student groups carrying out science activities. The specific aims were to study the emergence of SSMR in the different phases of the process, students’ participation in SSMR, and the relation of SSMR’s focus to the quality of outcomes, which was not explored in previous studies. The participants were 12-year-old students from the same class as in Study III. Five small groups consisting of four students and one of five students (N=25) were involved in the study. The small groups solved ill-defined science problems in an asynchronous CSCL environment, participating in research-like processes of inquiry over a total period of 22 hours. Written notes (N=4088) detailed the network discussions of the small groups and these constituted the study data. With these notes, SSMR threads were explored. As in Study III, the thread was used as the unit of analysis. In total, 332 notes were classified as forming 41 SSMR threads. Inter-coder agreement was assessed by three coders in the different phases of the analysis and found to be reliable. Multiple methods of analysis were used. Results showed that SSMR emerged in all the asynchronous CSCL inquiry processes in the small groups. However, the findings did not reveal any significantly changing trend in the emergence of SSMR during the process. As a main trend, the number of notes included in SSMR threads differed significantly in different phases of the process and small groups differed from each other. Although student participation was seen as highly dispersed between the students, there were differences between students and small groups. Furthermore, the findings indicated that the amount of SSMR during the process or participation structure did not explain the differences in the quality of outcomes for the groups. Rather, when SSMRs were focused on understanding and procedural matters, it was associated with achieving high quality learning outcomes. In turn, when SSMRs were focused on incidental and procedural matters, it was associated with low level learning outcomes. Hence, the findings imply that the focus of any emerging SSMR is crucial to the quality of the learning outcomes. Moreover, the findings encourage the use of multiple research methods for studying SSMR. In total, the four studies convincingly indicate that a phenomenon of socially shared metacognitive regulation also exists. This means that it was possible to define the concept of SSMR theoretically, to investigate it methodologically and to validate it empirically in two different learning contexts across dyads and small groups. In-depth micro-level case analysis in Studies I and III showed the possibility to capture and analyse in detail SSMR during the collaborative process, while in Studies II and IV, the analysis validated the emergence of SSMR in larger data sets. Hence, validation was tested both between two environments and within the same environments with further cases. As a part of this dissertation, SSMR’s detailed functions and foci were revealed. Moreover, the findings showed the important role of observable metacognitive experiences as the starting point of SSMRs. It was apparent that problems dealt with by the groups should be rather difficult if SSMR is to be made clearly visible. Further, individual students’ participation was found to differ between students and groups. The multiple research methods employed revealed supplementary findings regarding SSMR. Finally, when SSMR was focused on understanding and procedural matters, this was seen to lead to higher quality learning outcomes. Socially shared metacognition regulation should therefore be taken into consideration in students’ collaborative learning at school similarly to how an individual’s metacognition is taken into account in individual learning.

FUTURES OF FINNISH FOOD SYSTEM BY 2050. The perspective of resilience

Modern food systems face complex global challenges such as climate change, resource scarcities, population growth, concentration and globalization. It is not possible to forecast how all these challenges will affect food systems, but futures research methods provide possibilities to enable better understanding of possible futures and that way increases futures awareness. In this thesis, the two-round online Delphi method was utilized to research experts’ opinions about the present and the future resilience of the Finnish food system up to 2050. The first round questionnaire was constructed based on the resilience indicators developed for agroecosystems. Sub-systems in the study were primary production (main focus), food industry, retail and consumption. Based on the results from the first round, the future images were constructed for primary production and food industry sub-sections. The second round asked experts’ opinion about the future images’ probability and desirability. In addition, panarchy scenarios were constructed by using the adaptive cycle and panarchy frameworks. Furthermore, a new approach to general resilience indicators was developed combining “categories” of the social ecological systems (structure, behaviors and governance) and general resilience parameters (tightness of feedbacks, modularity, diversity, the amount of change a system can withstand, capacity of learning and self- organizing behavior). The results indicate that there are strengths in the Finnish food system for building resilience. According to experts organic farms and larger farms are perceived as socially self-organized, which can promote innovations and new experimentations for adaptation to changing circumstances. In addition, organic farms are currently seen as the most ecologically self-regulated farms. There are also weaknesses in the Finnish food system restricting resilience building. It is important to reach optimal redundancy, in which efficiency and resilience are in balance. In the whole food system, retail sector will probably face the most dramatic changes in the future, especially, when panarchy scenarios and the future images are reflected. The profitability of farms is and will be a critical cornerstone of the overall resilience in primary production. All in all, the food system experts have very positive views concerning the resilience development of the Finnish food system in the future. Sometimes small and local is beautiful, sometimes large and international is more resilient. However, when probabilities and desirability of the future images were questioned, there were significant deviations. It appears that experts do not always believe desirable futures to materialize.
