    Goals. The main focus of my Master's thesis was to discuss knowledge management as a part of activity and learning in the networked and diverged business. The research sites composed of two companies operating in separate (packaging and energy) branches. Thus it was interesting to study what possible influences and consequences diverse branches, products (package and electric component) with their life cycle and production processes might have in knowledge management. The aim was also to comprehend similarities and differences in object of activity, knowledge management and network in order to see the possible impacts on the development of the company's operations and activities as well as learning of the personnel. Theoretical framework. The thesis is based on developmental work research which has its roots in cultural-historical activity theory. The core concept of the framework is object-oriented, culturally mediated activity. It is an approach which combines scientific study, practical development work and learning. Essential is the role of the object that motivates human activity and its development. The key notions, knowledge management and network, have been discussed in the light of economics and educational sciences. The concept of learning in the thesis rests on expansive learning and investigative learning. Methods. The data for my thesis was gathered in dialogical workshops which are based on the socio-technical theory and method called work conference. Both quantitative and qualitative methods were used for the analysis of the data. Quantitative analysis was used to become familiar with the structure of the discussion in the workshops. The themes of research questions' - object of activity, knowledge management and network were analysed using qualitative analysis. The comparison of the two companies was carried out also by qualitative method. The thread of my analysis was to connect the findings into the production processes and the common object of the companies' activities. Results and Conclusions. The products of the researched companies proved to be technically demanding and competence-based items. The package is a separate product where as electric component is one part in an energy production entity. The life cycle of these products were different which meant that knowledge management related to them was diverse. The stress of knowledge management was in the phase of product design in both cases. The need of knowledge shrank when the package moved to the production phase. In case of the electric component the knowledge management was essential through the product life cycle since the development of the electric component continued also in the production phase. The customer's role as a knowledge producer is of paramount importance, also in case of knowledge held by the customer's other partners. External networks were stratified including the company's internal net, the external immediate net and the external remote net. Furthermore in the Electric company there was a bipolar internal net around which the knowledge management was intertwined. Expansion and deepening of network collaboration came up clearly as one way to improve knowledge management. Product and activity concepts showed also to be possible methods to develop networks and their knowledge management in order to support collaboration within network partners. The internal networks can be developed in a similar manner. The development of the concepts as co-development with network partners would make it possible to share competencies in order to contribute learning and expertise. The motives of learning would be embedded in the motives and interests of the common activity as the motives gears the learning actions.

    Semantics is a study of meaning in language and basis for language comprehension. How these phenomena are processed in the brain is still unclear especially in naturalistic context. In this study, naturalistic language comprehension, and how semantic processing in a narrative context is reflected in brain activity were investigated. Subjects were measured with functional magnetic resonance imaging (fMRI) while listening to a narrative. The semantic content of the narrative was modelled computationally with word2vec and compared to voxel-wise blood-oxygen-level dependent (BOLD) brain signal time courses using ridge regression. This approach provides a novel way to extract more detailed information from the brain data based on semantic content of the stimulus. Inter-subject correlation (ISC) of voxel-wise BOLD signals alone showed both hemispheres taking part in language comprehension. Areas involved in this task overlapped with networks of mentalisation, memory and attention suggesting comprehension requiring other modalities of cognition for its function. Ridge regression suggested cerebellum, superior, middle and medial frontal, inferior and medial parietal and visual cortices bilaterally and temporal cortex on right hemisphere having a role in semantic processing of the narrative. As similar results have been found in previous research on semantics, word2vec appears to model semantics sufficiently and is an applicable tool in brain research. This study suggests contextual language recruiting brain areas in both hemispheres and semantic processing showing as distributed activity on the cortex. This activity is likely dependent on the content of language, but further studies are required to distinguish how strongly brain activity is affected by different semantic contents.

    The new POPS 2014 emphasizes elementary school's responsibility on teaching working life skills more than before. As a part of studies in elementary school there is a Introduction to Working Life period ("TET" Period) that introduces working life to pupils in practice. Making TET Period rewarding for a pupil requires a lot of active contribution from the employer's side too. The goal of this developmental study is to create and facilitate fluent co-operation between YIT Group and elementary schools. Means for reaching the goal is developing and arranging a versatile TET Period which is rewarding to all the stakeholders; the student, the company and the school. This study was conducted by applying the methods of Desing-Based-Research in two cycles. The development bases on literature and earlier studies in youth education and working life, POPS, Introduction-to-working-life as a part of compulsory education, company social responsibility, learning and different learning environments. Key questions were: "What have the pupils learned about YIT business and its work community during the Introduction-to-working-life period?", "Which aspects the instructors and students considered as high-importance matters in the TET Course?". Research material consists of student questionnaires, theme interviews of the students and some of YIT personnel, students' filled TET work applications forms and observations material. Analysis of the material was conducted using qualitative content analysis method. The research takes place between fall 2015 and spring 2016. Altogether ten Introduction to Working Life periods were arranged: four for ninth grade students during fall 2015 and six for eight-graders during spring 2016. In 2015 attendance was thirteen pupils and in 2016 it was fourteen. The goal was to find out about pupils' learnings and which aspects need to be taken into account in arrangements. This study concludes that the pupils' understanding on company operations and its different professionals improved and became more versatile. Furthermore, the pupils were able to list factors that relate to meaningful work life in more detail. However, their dream professions mainly stayed as earlier. According to pupils the most positive things in the TET Period were nice atmosphere and variable content. On the other hand the most of the instructors felt like that the TET Period requires planning and extra work. Based on observations one may run into surprises during the arrangements. Thus, a clear plan as well as direct communication between all parties facilitate success.

    Tutkielmassa tarkastellaan suomalaisten opiskelijanuorten käsitystä perheestä. Tutkielma on osa kansainvälistä Eurooppalainen kielellinen maailmankuva -projektia (EUROJOS), jonka tarkoituksena on selvittää slaavien ja heidän naapurikansojensa aksiologisia konsepteja, kuten koti ja työ. Tutkielmani aiheena on perhekonsepti suomalaisten nuorten näkökulmasta. Tutkimusaineisto on kerätty syksyllä 2017 anonyymisti 106:lle Helsingin yliopiston eri ainejärjestön sähköpostilistalle lähetetyllä sähköisellä lomakkeella, joka oli tarkoitettu Suomessa vähintään esikoululaisesta asuneille 17–30-vuotiaille opiskelijoille. Vastaajia pyydettiin mm. määrittelemään sekä oma että yleinen käsitys perheestä kysymällä mm. Mikä on oikea perhe ja Milloin perhe lakkaa olemasta perhe? Kyselyyn vastasi määräaikaan mennessä 275 henkilöä, joista sadan vastaukset valikoituivat kohderyhmäksi siten, että joukossa olisi mahdollisimman monen eri alan ja sukupuoli-identiteetin edustajia. Aineistoa analysoitiin puolalaisen etnolingvistiikkakoulukunnan kehittämällä monitieteellisellä metodilla, jonka yhtenä keskeisenä keinona on tutkittavan konseptin oikeellisuuden selvittäminen. Tutkimuksessa analysoitiin myös sekä perinteisiä että nykyaikaisia perheeseen liittyviä sanontoja, joista esitettiin erillinen kysymys. Tutkimus osoittaa, että oikea perhe on subjektiivinen käsite tai sitä ei ole olemassakaan. Suomalaisnuorille tärkeintä perheessä on omaehtoisuus: emotionaalinen side painaa enemmän kuin (veri)sukulaisuus.
