As companies become more efficient with respect to their internal processes, they begin to shift the focus beyond their corporate boundaries. Thus, the recent years have witnessed an increased interest by practitioners and researchers in interorganizational collaboration, which promises better firm performance through more effective supply chain management. It is no coincidence that this interest comes in parallel with the recent advancements in Information and Communication Technologies, which offer many new collaboration possibilities for companies. However, collaboration, or any other type of supply chain integration effort, relies heavily on information sharing. Hence, this study focuses on information sharing, in particular on the factors that determine it and on its value. The empirical evidence from Finnish and Swedish companies suggests that uncertainty (both demand and environmental) and dependency in terms of switching costs and asset specific investments are significant determinants of information sharing. Results also indicate that information sharing improves company performance regarding resource usage, output, and flexibility. However, companies share information more intensely at the operational rather than the strategic level. The use of supply chain practices and technologies is substantial but varies across the two countries. This study sheds light on a common trend in supply chains today. Whereas the results confirm the value of information sharing, the contingent factors help to explain why the intensity of information shared across companies differ. In the future, competitive pressures and uncertainty are likely to intensify. Therefore, companies may want to continue with their integration efforts by focusing on the determinants discussed in this study. However, at the same time, the possibility of opportunistic behavior by the exchange partner cannot be disregarded.

This study offers a reconstruction and critical evaluation of globalization theory, a perspective that has been central for sociology and cultural studies in recent decades, from the viewpoint of media and communications. As the study shows, sociological and cultural globalization theorists rely heavily on arguments concerning media and communications, especially the so-called new information and communication technologies, in the construction of their frameworks. Together with deepening the understanding of globalization theory, the study gives new critical knowledge of the problematic consequences that follow from such strong investment in media and communications in contemporary theory. The book is divided into four parts. The first part presents the research problem, the approach and the theoretical contexts of the study. Followed by the introduction in Chapter 1, I identify the core elements of globalization theory in Chapter 2. At the heart of globalization theory is the claim that recent decades have witnessed massive changes in the spatio-temporal constitution of society, caused by new media and communications in particular, and that these changes necessitate the rethinking of the foundations of social theory as a whole. Chapter 3 introduces three paradigms of media research the political economy of media, cultural studies and medium theory the discussion of which will make it easier to understand the key issues and controversies that emerge in academic globalization theorists treatment of media and communications. The next two parts offer a close reading of four theorists whose works I use as entry points into academic debates on globalization. I argue that we can make sense of mainstream positions on globalization by dividing them into two paradigms: on the one hand, media-technological explanations of globalization and, on the other, cultural globalization theory. As examples of the former, I discuss the works of Manuel Castells (Chapter 4) and Scott Lash (Chapter 5). I maintain that their analyses of globalization processes are overtly media-centric and result in an unhistorical and uncritical understanding of social power in an era of capitalist globalization. A related evaluation of the second paradigm (cultural globalization theory), as exemplified by Arjun Appadurai and John Tomlinson, is presented in Chapter 6. I argue that due to their rejection of the importance of nation states and the notion of cultural imperialism for cultural analysis, and their replacement with a framework of media-generated deterritorializations and flows, these theorists underplay the importance of the neoliberalization of cultures throughout the world. The fourth part (Chapter 7) presents a central research finding of this study, namely that the media-centrism of globalization theory can be understood in the context of the emergence of neoliberalism. I find it problematic that at the same time when capitalist dynamics have been strengthened in social and cultural life, advocates of globalization theory have directed attention to media-technological changes and their sweeping socio-cultural consequences, instead of analyzing the powerful material forces that shape the society and the culture. I further argue that this shift serves not only analytical but also utopian functions, that is, the longing for a better world in times when such longing is otherwise considered impracticable.

The thesis examines the intensification and characteristics of a policy that emphasises economic competitiveness in Finland during the 1990s and early 2000s. This accentuation of economic objectives is studied at the level of national policy-making as well as at the regional level through the policies and strategies of cities and three universities in the Helsinki region. By combining the analysis of state policies, urban strategies and university activities, the study illustrates the pervasiveness of the objective of economic competitiveness and growth across these levels and sheds light on the features and contradictions of these policies on a broad scale. The thesis is composed of five research articles and a summary article. At the level of national policies, the central focus of the thesis is on the growing role of science and technology policy as a state means to promote structural economic change and its transformation towards a broader, yet ambivalent concept of innovation policy. This shift brings forward a tension between an increasing emphasis on economic aspects – innovations and competitiveness – as well as the expanding scope of issues across a wide range of policy sectors that are being subsumed under this market- and economy oriented framework. Related to science and technology policy, attention is paid to adjustments in university policy in which there has been increasing pressure for efficiency, rationalisation and commercialisation of academic activities. Furthermore, political efforts to build an information society through the application of information and communication technologies are analysed with particular attention to the balance between economic and social objectives. Finally, changes in state regional policy priorities and the tendency towards competitiveness are addressed. At the regional level, the focus of the thesis is on the policies of the cities in Finland’s capital region as well as strategies of three universities operating in the region, namely the University of Helsinki, Helsinki University of technology and Helsinki School of Economics. As regards the urban level, the main focus is on the changes and characteristics of the urban economic development policy of the City of Helsinki. With respect to the universities, the thesis examines their attempts to commercialise research and thus bring academic research closer to economic interests, and pays particular attention to the contradictions of commercialisation. Related to the universities, the activities of three intermediary organisations that the universities have established in order to increase cooperation with industry are analysed. These organisations are the Helsinki Science Park, Otaniemi International Innovation Centre and LTT Research Ltd. The summary article provides a synthesis of the material presented in the five original articles and relates the results of the articles to a broader discussion concerning the emergence of competition states and entrepreneurial cities and regions. The main points of reference are Bob Jessop’s and Neil Brenner’s theses on state and urban-regional restructuring. The empirical results and considerations from Finland and the Helsinki region are used to comment on, specify and criticise specific parts of the two theses.

A model of the information and material activities that comprise the overall construction process is presented, using the SADT activity modelling methodology. The basic model is further refined into a number of generic information handling activities such as creation of new information, information search and retrieval, information distribution and person-to-person communication. The viewpoint could be described as information logistics. This model is then combined with a more traditional building process model, consisting of phases such as design and construction. The resulting two-dimensional matrix can be used for positioning different types of generic IT-tools or construction specific applications. The model can thus provide a starting point for a discussion of the application of information and communication technology in construction and for measurements of the impacts of IT on the overall process and its related costs.

This thesis explores the relationship between humans and ICTs (information and communication technologies). As ICTs are increasingly penetrating all spheres of social life, their role as mediators – between people, between people and information, and even between people and the natural world – is expanding, and they are increasingly shaping social life. Yet, we still know little of how our life is affected by their growing role. Our understanding of the actors and forces driving the accelerating adoption of new ICTs in all areas of life is also fairly limited. This thesis addresses these problems by interpretively exploring the link between ICTs and the shaping of society at home, in the office, and in the community. The thesis builds on empirical material gathered in three research projects, presented in four separate essays. The first project explores computerized office work through a case study. The second is a regional development project aiming at increasing ICT knowledge and use in 50 small-town families. In the third, the second project is compared to three other longitudinal development projects funded by the European Union. Using theories that consider the human-ICT relationship as intertwined, the thesis provides a multifaceted description of life with ICTs in contemporary information society. By oscillating between empirical and theoretical investigations and balancing between determinist and constructivist conceptualisations of the human-ICT relationship, I construct a dialectical theoretical framework that can be used for studying socio-technical contexts in society. This framework helps us see how societal change stems from the complex social processes that surround routine everyday actions. For example, interacting with and through ICTs may change individuals’ perceptions of time and space, social roles, and the proper ways to communicate – changes which at some point in time result in societal change in terms of, for example, new ways of acting and knowing things.

During recent years the commercialisation of sex has increased and intensified both locally and globally. This thesis explores the commercialisation of bodies, sex and sexualities, particularly the sex trade, and the impact of rapidly evolving information and communication technologies on this globalising trade. The main focus of this work is on the policies, discourses and policy developments in the area especially in the Finnish context. The study is based on multidisciplinary theoretical sources through which the framework of multiple linkages relevant to the commercialisation of sex is conceptualised. The sex trade functions through a web of intersecting linkages of a substantive, economic, organisational, temporal, spatial, cultural, technological, as well as of legislative and policy nature. This framework of linkages forms the basis for the analysis of the main empirical data, namely qualitative interviews with thirty key managers and professionals, who are responsible for the preparation and implementation of policies on commercial sex. In addition, the thesis addresses the policies and policy practices on the sex trade through the analysis of national and international policy instruments. In addition to analysing the processes of the commercialisation of sex and its effects, the study also discusses their further implications for organisational policy-making, research, and society more generally. The thesis thus seeks to contribute to practice, research and theory on gender, management and organisations.

Tutkimus käsittelee verkko-opetusinnovaation leviämistä perusasteen ja lukion maantieteeseen vuosina 1998–2004. Työssä sovellettiin opetusinnovaation leviämismallia ja innovaatioiden diffuusioteoriaa. Aineisto hankittiin seitsemänä vuotena kyselylomakkeilla maantieteen verkko-opetuksen edelläkävijäopettajilta, jotka palauttivat 326 lomaketta. Tutkimuksen pääongelmat olivat 1) Millaisia edellytyksiä edelläkävijäopettajilla on käyttää verkko-opetusta koulun maantieteessä? 2) Mitä sovelluksia ja millä tavoin edelläkävijäopettajat käyttävät maantieteen verkko-opetuksessa? 3) Millaisia käyttökokemuksia edelläkävijäopettajat ovat saaneet maantieteen verkko-opetuksesta? Tutkimuksessa havaittiin, että tietokoneiden riittämätön määrä ja puuttuminen aineluokasta vaikeuttivat maantieteen verkko-opetusta. Työssä kehitettiin opettajien digitaalisten mediataitojen kuutiomalli, johon kuuluvat tekniset taidot, informaation prosessointitaidot ja viestintätaidot. Opettajissa erotettiin kolme verkko-opetuksen käyttäjätyyppiä: informaatiohakuiset kevytkäyttäjät, viestintähakuiset peruskäyttäjät ja yhteistyöhakuiset tehokäyttäjät. Verkko-opetukseen liittyi intensiivisiä myönteisiä ja kielteisiä kokemuksia. Se toi iloa ja motivaatiota opiskeluun. Sitä pidettiin rikastuttavana lisänä, joka haluttiin integroida opetukseen hallitusti. Edelläkävijäopettajat ottivat käyttöön tietoverkoissa olevaa informaatiota ja sovelsivat työvälineohjelmia. He pääsivät alkuun todellisuutta jäljittelevien virtuaalimaailmojen: satelliittikuvien toistaman maapallon, digitaalikarttojen ja simulaatioiden käytössä. Opettajat kokeilivat verkon sosiaalisia tiloja reaaliaikaisen viestinnän, keskusteluryhmien ja ryhmätyöohjelmien avulla. Mielikuvitukseen perustuvat virtuaalimaailmat jäivät vähälle sillä opettajat eivät juuri pelanneet viihdepelejä. He omaksuivat virtuaalimaailmoista satunnaisia palasia käytettävissä olevan laite- ja ohjelmavarustuksen mukaan. Virtuaalimaailmojen valtaus eteni tutkimuksen aikana digitaalisen informaation hyödyntämisestä viestintäsovelluksiin ja aloittelevaan yhteistyöhön. Näin opettajat laajensivat virtuaalireviiriään tietoverkkojen dynaamisiksi toimijoiksi ja pääsivät uusin keinoin tyydyttämään ihmisen universaalia tarvetta yhteyteen muiden kanssa. Samalla opettajat valtautuivat informaation kuluttajista sen tuottajiksi, objekteista subjekteiksi. Verkko-opetus avaa koulun maantieteelle huomattavia mahdollisuuksia. Mobiililaitteiden avulla informaatiota voidaan kerätä ja tallentaa maasto-olosuhteissa, ohjelmilla sitä voidaan muuntaa muodosta toiseen. Internetin autenttiset ja ajantasaiset materiaalit tuovat opiskeluun konkretiaa ja kiinnostavuutta, mallit, simulaatiot ja paikkatieto havainnollistavat ilmiöitä. Viestintä- ja yhteistyövälineet sekä sosiaaliset informaatiotilat vahvistavat yhteistyötä. Avainsanat: verkko-opetus, internet, virtuaalimaailmat, maantiede, innovaatiot

Tutkimuksen päätarkoitus oli hahmottaa verkko-opetuksen arvoja ja arviointia luokanopettajan näkökulmasta. Teoreettisena viitekehyksenä oli mediakasvatus ja didaktiikan käsitys opetus opiskelu oppimisprosessista. Didaktisena perustana käytettiin Kansasen ym. (2000) opettajan pedagogista ajattelua, Lahdeksen (1997) didaktiikan kehämallia sekä Uljensin (1997) opetus opiskelu oppimisprosessia. Lähtökohtana oli luokanopettajan arvioinnin kautta pohtia opetuksen, opiskelun ja oppimisen sekä tieto- ja viestintätekniikan yhtymistä koulukontekstissa. Tutkimuksen pääongelmat olivat: 1) Minkälainen oli luokanopettajan käsitys verkko-opetuksen toteuttamisesta? 2) Miten luokanopettaja arvioi verkko-opetusta? Myös ensimmäistä pääongelmaa lähestyttiin arvojen ja arvioinnin näkökulmasta. Menetelmänä käytettiin teemahaastattelua. Teemahaastattelun teemoja jäsennettiin Gallinin (2001) sosiokulttuurisen verkko-opetuksen arviointimallin sekä Tellan ja Mononen-Aaltosen (2001) mediakasvatuksen monitasomallin avulla. Aineistonkeruussa kahdeksan helsinkiläistä luokanopettajaa vastasivat lyhyeen kyselyyn, jonka jälkeen heitä haastateltiin välittömästi. Laadullisen aineiston analyysissä teemoiteltiin aineisto, ja tämän rinnalla rakennettiin aineistolähtöistä analyysiä. Näiden vuorovaikutuksesta syntyivät tutkimuksen johtopäätökset. Keskeisinä tuloksina tutkimuksessa nähtiin luokanopettajan verkko-opetukseen liittyvien arvojen kaksi eri näkökulmaa: (A) opetus opiskelu oppimismenetelmien ja -tulosten arvonäkökulma sekä (B) ns. kasvatuksellinen ja koulukulttuurin arvonäkökulma. Arvonäkökulmien pohjalta hahmotettiin johtopäätöksissä erilaisia tasoja luokanopettajan opetuksen, opiskelun ja oppimisen arvioinnista, kun tieto- ja viestintätekniikka on mukana prosessissa. Kaksi tasoa tarkennettiin verkko-opetuksen arvioinnin fokuksiksi, jotka olivat (1) teknologinen ja (2) tavoitteinen fokus. Teknologisessa arvioinnin fokuksessa (1) arviointia hallitsee huoli oppilaasta ihmisenä. Arviointi liittyy joko siihen, että oppilaan on opittava perustaidot tieto- ja viestintätekniikassa ja ymmärrettävä Internetin mahdollisuudet, tai siihen, että opettaja pyrkii suojelemaan lapsia Internetin uhkilta ja liialliselta altistumiselta esimerkiksi digitaalisille peleille. Verkko-opetuksen tavoitteinen arvioinnin fokus (2) nojaa siihen, minkälaisia tavoitteita luokanopettaja yleisesti asettaa opetukselleen, vaikka tieto- ja viestintätekniikka ei liittyisikään prosessiin. Fokuksen taustalla on myös mediakasvatuksen näkökulma tieto- ja viestintätekniikan opetuskäyttöön, jolloin keskeistä on, että opetuksen suunnittelu ja arviointi ei lähde teknologiasta käsin vaan didaktiikasta ja peda-gogisista arvoista. Verkko-opetuksen arvioinnin fokusten voidaan nähdä täydentävän toisiaan. Fokusten varioinnissa voidaan puhua luokanopettajan kohdalla todellisesta mediataidosta, joka ulottuu yli ammatillisen pätevyyden aina opettajan henkilökohtaiseen kehittymisen kaareen. Avainsanat: Verkko-opetus, arvot, arviointi, opetus-opiskelu-oppimisprosessi, opettajan pedagoginen ajattelu, tieto- ja viestintätekniikan opetuskäyttö Keywords: Network-Based Education (NBE), values, evaluation, teaching-studying-learning process, teacher's pedagogical thinking, educational use of information and communication technologies (ICT)

This study investigates primary and secondary school teachers’ social representations and ways to conceptualise new technologies. The focus is both on teachers’ descriptions, interpretations and conceptions of technology and on the adoption and formation of these conceptions. In addition, the purpose of this study is to analyse how the national objectives of the information society and the implementation of information and communication technologies (ICT) in schools reflect teachers’ thinking and everyday practices. The starting point for the study is the idea of a dynamic and mutual relationship between teachers and technology so that technology does not affect one-sidedly teachers’ thinking. This relationship is described in this study as the teachers’ technology relationship. This concept emphasises that technology cannot be separated from society, social relations and the context where it is used but it is intertwined with societal practices and is therefore formed in interaction with the material and social factors. The theoretical part of this study encompasses three different research traditions: 1) the social shaping of technology, 2) research on how schools and teachers use technology and 3) social representations theory. The study was part of the Helmi Project (Holistic development of e-Learning and business models) in 2001–2005 at the Helsinki University of Technology, SimLab research unit. The Helmi Project focused on different aspects of the utilisation of ICT in teaching. The research data consisted of interviews of teachers and principals. Altogether 37 interviews were conducted in 2003 and 2004 in six different primary and secondary schools in Espoo, Finland. The data was analysed applying grounded theory. The results showed that the teachers’ technology relationship was diverse and context specific. Technology was interpreted differently depending on the context: the teachers’ technology related descriptions and metaphors illustrated on one hand the benefits and the possibilities and on the other hand the problems and threats of different technologies. The dualist nature of technology was also expressed in the teachers’ thinking about technology as a deterministic and irrevocable force and as a controllable and functional tool at the same time. Teachers did not consider technology as having a stable character but they interpreted technology in relation to the variable context of use. This way they positioned or anchored technology into their everyday practices. The study also analysed the formation of the teachers’ technology relationship and the ways teachers familiarise themselves with new technologies. Comparison of different technologies as well as technology related metaphors turned out to be significant in forming the technology relationship. Also the ways teachers described the familiarisation process and the interpretations of their own technical skills affected the formation of technology relationship. In addition, teachers defined technology together with other teachers, and the discussions reflected teachers’ interpretations and descriptions.

The aim of the doctoral dissertation was to further our theoretical and empirical understanding of media education as practised in the context of Finnish basic education. The current era of intensive use of the Internet is recognised too. The doctoral dissertation presents the subject didactic dimension of media education as one of the main results of the conceptual analysis. The theoretical foundation is based on the idea of dividing the concept of media education into media and education (Vesterinen et al., 2006). As two ends of the dimension, these two can be understood didactically as content and pedagogy respectively. In the middle, subject didactics is considered to have one form closer to content matter (Subject Didactics I learning about media) and another closer to general pedagogical questions (Subject Didactics II learning with/through media). The empirical case studies of the dissertation are reported with foci on media literacy in the era of Web 2.0 (Kynäslahti et al., 2008), teacher reasoning in media educational situations (Vesterinen, Kynäslahti - Tella, 2010) and the research methodological implications of the use of information and communication technologies in the school (Vesterinen, Toom - Patrikainen, 2010). As a conclusion, Media-Based Media Education and Cross-Curricular Media Education are presented as two subject didactic modes of media education in the school context. Episodic Media Education is discussed as the third mode of media education where less organised teaching, studying and learning related to media takes place, and situations (i.e. episodes, if you like) without proper planning or thorough reflection are in focus. Based on the theoretical and empirical understanding gained in this dissertation, it is proposed that instead of occupying a corner of its own in the school curriculum, media education should lead the wider change in Finnish schools.
