Future revenue models: Transformation from textbooks to digital solutions in the educational publishing industry, Case Sanoma Learning

This study was conducted in order to learn how companies’ revenue models will be transformed due to the digitalisation of its products and processes. Because there is still only a limited number of researches focusing solely on revenue models, and particularly on the revenue model change caused by the changes at the business environment, the topic was initially approached through the business model concept, which organises the different value creating operations and resources at a company in order to create profitable revenue streams. This was used as the base for constructing the theoretical framework for this study, used to collect and analyse the information. The empirical section is based on a qualitative study approach and multiple-case analysis of companies operating in learning materials publishing industry. Their operations are compared with companies operating in other industries, which have undergone comparable transformation, in order to recognise either similarities or contrasts between the cases. The sources of evidence are a literature review to find the essential dimensions researched earlier, and interviews 29 of managers and executives at 17 organisations representing six industries. Based onto the earlier literature and the empirical findings of this study, the change of the revenue model is linked with the change of the other dimen-sions of the business model. When one dimension will be altered, as well the other should be adjusted accordingly. At the case companies the transformation is observed as the utilisation of several revenue models simultaneously and the revenue creation processes becoming more complex.

In vitro ectomycorrhiza formation by monokaryotic and dikaryotic isolates of Pisolithus microcarpus in Eucalyptus grandis

The formation of ectomycorrhizas by monokaryotic and dikaryotic isolates of Pisolithus microcarpus (Cooke & Massee) G. Cunn. in Eucalyptus grandis W. Hill ex Maid. was studied by in vitro synthesis in Petri dishes. The formation of ectomycorrhizas was observed for all strains tested. Ectomycorrhizas formed by the monokaryotic strains presented a sheath of hyphae around the roots and a Hartig net limited to the epidermis layer, typical of the angiosperm ectomycorrhizas. Colonization rates, a measure of the number of ectomycorrhizas in relation to the total number of lateral root tips, varied from 23 to 62%. Some monokaryotic strains stimulated the formation of lateral roots, promoting increases of up to 109% above the control. The presence of some of the isolates in the in vitro synthesis medium stimulated the production of thicker lateral root tips. The dimensions of the lateral roots tips and ectomycorrhizas varied from one isolate to the next, indicating a variation in their capacity to provoke morphological changes in the host plant roots. The dikaryotic strain M5M11 presented higher values for lateral root yield, number of ectomycorrhizas, and colonization percentage than the corresponding monokaryotic strains, M5 and M11. This indicated the possibility of selecting compatible performing monokaryotic isolates for the yield of superior dikaryotic strains. The set of monokaryotic strains tested varied greatly in their ability to colonize E. grandis roots and cause secondary metabolism-related morphological changes in roots, providing a wealth of model systems for the study of genetic, physiological, and morphogenetic processes involved in Pisolithus-Eucalyptus ectomycorrhiza formation.

Evaluation of energy efficiency and best available techniques in pumping processes

The potential for enhancing the energy efficiency of industrial pumping processes is estimated to be in some cases up to 50 %. One way to define further this potential is to implement techniques in accordance to definition of best available techniques in pumping applications. These techniques are divided into three main categories: Design, control method & maintenance and distribution system. In the theory part of this thesis first the definition of best available techniques (BAT) and its applicability on pumping processes is issued. Next, the theory around pumping with different pump types is handled, the main stress being in centrifugal pumps. Other components needed in a pumping process are dealt by presenting different control methods, use of an electric motor, variable speed drive and the distribution system. Last part of the theory is about industrial pumping processes from water distribution, sewage water and power plant applications, some of which are used further on in the empirical part as example cases. For the empirical part of this study four case studies on typical pumping processes from older Master’s these were selected. Firstly the original results were analyzed by studying the distribution of energy consumption between different system components and using the definition of BAT in pumping, possible ways to improve energy efficiency were evaluated. The goal in this study was that by the achieved results it would be possible to identify the characteristic energy consumption of these and similar pumping processes. Through this data it would then be easier to focus energy efficiency actions where they might be the most applicable, both technically and economically.

Recovery and refining of manganese as by-product from hydrometallurgical processes

The consumption of manganese is increasing, but huge amounts of manganese still end up in waste in hydrometallurgical processes. The recovery of manganese from multi-metal solutions at low concentrations may not be economical. In addition, poor iron control typically prevents the production of high purity manganese. Separation of iron from manganese can be done with chemical precipitation or solvent extraction methods. Combined carbonate precipitation with air oxidation is a feasible method to separate iron and manganese due to the fast kinetics, good controllability and economical reagents. In addition the leaching of manganese carbonate is easier and less acid consuming than that of hydroxide or sulfide precipitates. Selective iron removal with great efficiency from MnSO4 solution is achieved by combined oxygen or air oxidation and CaCO3 precipitation at pH > 5.8 and at a redox potential of > 200 mV. In order to avoid gypsum formation, soda ash should be used instead of limestone. In such case, however, extra attention needs to be paid on the reagents mole ratios in order to avoid manganese coprecipitation. After iron removal, pure MnSO4 solution was obtained by solvent extraction using organophosphorus reagents, di-(2-ethylhexyl)phosphoric acid (D2EHPA) and bis(2,4,4- trimethylpentyl)phosphinic acid (CYANEX 272). The Mn/Ca and Mn/Mg selectivities can be increased by decreasing the temperature from the commonly used temperatures (40 –60oC) to 5oC. The extraction order of D2EHPA (Ca before Mn) at low temperature remains unchanged but the lowering of temperature causes an increase in viscosity and slower phase separation. Of these regents, CYANEX 272 is selective for Mn over Ca and, therefore, it would be the better choice if there is Ca present in solution. A three-stage Mn extraction followed by a two-stage scrubbing and two-stage sulfuric acid stripping is an effective method of producing a very pure MnSO4 intermediate solution for further processing. From the intermediate MnSO4 some special Mn- products for ion exchange applications were synthesized and studied. Three types of octahedrally coordinated manganese oxide materials as an alternative final product for manganese were chosen for synthesis: layer structured Nabirnessite, tunnel structured Mg-todorokite and K-kryptomelane. As an alternative source of pure MnSO4 intermediate, kryptomelane was synthesized by using a synthetic hydrometallurgical tailings. The results show that the studied OMS materials adsorb selectively Cu, Ni, Cd and K in the presence of Ca and Mg. It was also found that the exchange rates were reasonably high due to the small particle dimensions. Materials are stable in the studied conditions and their maximum Cu uptake capacity was 1.3 mmol/g. Competitive uptake of metals and acid was studied using equilibrium, batch kinetic and fixed-bed measurements. The experimental data was correlated with a dynamic model, which also accounts for the dissolution of the framework manganese. Manganese oxide micro-crystals were also bound onto silica to prepare a composite material having a particle size large enough to be used in column separation experiments. The MnOx/SiO2 ratio was found to affect significantly the properties of the composite. The higher the ratio, the lower is the specific surface area, the pore volume and the pore size. On the other hand, higher amount of silica binder gives composites better mechanical properties. Birnesite and todorokite can be aggregated successfully with colloidal silica at pH 4 and with MnO2/SiO2 weight ratio of 0.7. The best gelation and drying temperature was 110oC and sufficiently strong composites were obtained by additional heat-treatment at 250oC for 2 h. The results show that silica–supported MnO2 materials can be utilized to separate copper from nickel and cadmium. The behavior of the composites can be explained reasonably well with the presented model and the parameters estimated from the data of the unsupported oxides. The metal uptake capacities of the prepared materials were quite small. For example, the final copper loading was 0.14 mmol/gMnO2. According to the results the special MnO2 materials are potential for a specific environmental application to uptake harmful metal ions.

Making Sense of Shared Leadership. A case study of leadership processes and practices without formal leadership structure in the team context

Leadership is essential for the effectiveness of the teams and organizations they are part of. The challenges facing organizations today require an exhaustive review of the strategic role of leadership. In this context, it is necessary to explore new types of leadership capable of providing an effective response to new needs. The presentday situations, characterized by complexity and ambiguity, make it difficult for an external leader to perform all leadership functions successfully. Likewise, knowledge-based work requires providing professional groups with sufficient autonomy to perform leadership functions. This study focuses on shared leadership in the team context. Shared leadership is seen as an emergent team property resulting from the distribution of leadership influence across multiple team members. Shared leadership entails sharing power and influence broadly among the team members rather than centralizing it in the hands of a single individual who acts in the clear role of a leader. By identifying the team itself as a key source of influence, this study points to the relational nature of leadership as a social construct where leadership is seen as social process of relating processes that are co-constructed by several team members. Based on recent theoretical developments concerned with relational, practice-based and constructionist approaches to the study of leadership processes, this thesis proposes the study of leadership interactions, working processes and practices to focus on the construction of direction, alignment and commitment. During the research process, critical events, activities, working processes and practices of a case team have been examined and analyzed with the grounded theory –approach in the terms of shared leadership. There are a variety of components to this complex process and a multitude of factors that may influence the development of shared leadership. The study suggests that the development process of shared leadership is a common sense -making process and consists of four overlapping dimensions (individual, social, structural, and developmental) to work with as a team. For shared leadership to emerge, the members of the team must offer leadership services, and the team as a whole must be willing to rely on leadership by multiple team members. For these individual and collective behaviors to occur, the team members must believe that offering influence to and accepting it from fellow team members are welcome and constructive actions. Leadership emerges when people with differing world views use dialogue and collaborative learning to create spaces where a shared common purpose can be achieved while a diversity of perspectives is preserved and valued. This study also suggests that this process can be supported by different kinds of meaning-making and process tools. Leadership, then, does not reside in a person or in a role, but in the social system. The built framework integrates the different dimensions of shared leadership and describes their relationships. This way, the findings of this study can be seen as a contribution to the understanding of what constitutes essential aspects of shared leadership in the team context that can be of theoretical value in terms of advancing the adoption and development process of shared leadership. In the real world, teams and organizations can create conditions to foster and facilitate the process. We should encourage leaders and team members to approach leadership as a collective effort that the team can be prepared for, so that the response is rapid and efficient.

Modelling of combustion and sorbent reactions in three-dimensional flow environment of a circulating fluidized bed furnace

This thesis presents a three-dimensional, semi-empirical, steady state model for simulating the combustion, gasification, and formation of emissions in circulating fluidized bed (CFB) processes. In a large-scale CFB furnace, the local feeding of fuel, air, and other input materials, as well as the limited mixing rate of different reactants produce inhomogeneous process conditions. To simulate the real conditions, the furnace should be modelled three-dimensionally or the three-dimensional effects should be taken into account. The only available methods for simulating the large CFB furnaces three-dimensionally are semi-empirical models, which apply a relatively coarse calculation mesh and a combination of fundamental conservation equations, theoretical models and empirical correlations. The number of such models is extremely small. The main objective of this work was to achieve a model which can be applied to calculating industrial scale CFB boilers and which can simulate all the essential sub-phenomena: fluid dynamics, reactions, the attrition of particles, and heat transfer. The core of the work was to develop the model frame and the required sub-models for determining the combustion and sorbent reactions. The objective was reached, and the developed model was successfully used for studying various industrial scale CFB boilers combusting different types of fuel. The model for sorbent reactions, which includes the main reactions for calcitic limestones, was applied for studying the new possible phenomena occurring in the oxygen-fired combustion. The presented combustion and sorbent models and principles can be utilized in other model approaches as well, including other empirical and semi-empirical model approaches, and CFD based simulations. The main achievement is the overall model frame which can be utilized for the further development and testing of new sub-models and theories, and for concentrating the knowledge gathered from the experimental work carried out at bench scale, pilot scale and industrial scale apparatus, and from the computational work performed by other modelling methods.

Polymer surface modification by atomic layer deposition

Current industrial atomic layer deposition (ALD) processes are almost wholly confined to glass or silicon substrates. For many industrial applications, deposition on polymer substrates will be necessary. Current deposition processes are also typically carried out at temperatures which are too high for polymers. If deposition temperatures in ALD can be reduced to the level applicable for polymers, it will open new interesting areas and applications for polymeric materials. The properties of polymers can be improved for example by coatings with functional and protective properties. Although the ALD has shown its capability to operate at low temperatures suitable for polymer substrates, there are other issues related to process efficiency and characteristics of different polymers where new knowledge will assist in developing industrially conceivable ALD processes. Lower deposition temperature in ALD generally means longer process times to facilitate the self limiting film growth mode characteristic to ALD. To improve process efficiency more reactive precursors are introduced into the process. For example in ALD oxide processes these can be more reactive oxidizers, such as ozone and oxygen radicals, to substitute the more conventionally used water. Although replacing water in the low temperature ALD with ozone or plasma generated oxygen radicals will enable the process times to be shortened, they may have unwanted effects both on the film growth and structure, and in some cases can form detrimental process conditions for the polymer substrate. Plasma assistance is a very promising approach to improve the process efficiency. The actual design and placement of the plasma source will have an effect on film growth characteristics and film structure that may retard the process efficiency development. Due to the fact that the lifetime of the radicals is limited, it requires the placement of the plasma source near to the film growth region. Conversely this subjects the substrate to exposure byother plasma species and electromagnetic radiation which sets requirements for plasma conditions optimization. In this thesis ALD has been used to modify, activate and functionalize the polymer surfaces for further improvement of polymer performance subject to application. The issues in ALD on polymers, both in thermal and plasma-assisted ALD will be further discussed.

Military crisis management in the next decade (2020-2030) : inducing consent or relying on compliance?

The most outstanding conceptual challenge of modern crisis management is the principle of consent. It is not a problem only at the operational level - it challenges the entire decision-making structures of crisis management operations. In post-cold war times and especially in the 21st century, there has been a transition from peacekeeping with limited size and scope towards large and complex peace operations. This shift has presented peace operations with a dilemma. How to balance between maintaining consent for peace operations, whilst being able to use military force to coerce those attempting to wreck peace processes? To address such a dilemma, this research aims to promote understanding, on what can be achieved by military crisis management operations (peace support operations) in the next decade. The research concentrates on the focal research question: Should military components induce consent or rely on the compliance of conflicting parties in crisis management operations of the next decade (2020 – 2030)? The focus is on military – political strategic level considerations, and especially on the time before political decisions to commit to a crisis management operation. This study does not focus on which actor or organisation should intervene. The framework of this thesis derives from the so called ‘peacebuilding space’, the scope of peace operations and spoiler theory. Feasibility of both peace enforcement and peacekeeping in countering future risk conditions are analysed in this framework. This future-orientated qualitative research uses the Delphi-method with a panel of national and international experts. Citation analysis supports identification of relevant reference material, which consists of contemporary literature, the Delphi-questionnaires and interviews. The research process followed three main stages. In the first stage, plausible future scenarios and risk conditions were identified with the Delphi-panel. In the second stage, operating environments for peace support operations were described and consequent hypotheses formulated. In the third stage, these hypotheses were tested on the Delphi-panel. The Delphi-panel is sufficiently wide and diverse to produce plausible yet different insights. The research design utilised specifically military crisis management and peace operations theories. This produced various and relevant normative considerations. Therefore, one may argue that this research; which is based on accepted contemporary theory, hypotheses derived thereof and utilising an expert panel, contributes to the realm of peace support operations. This research finds that some degree of peace enforcement will be feasible and necessary in at least the following risk conditions: failed governance; potential spillover of ethnic, religious, ideological conflict; vulnerability of strategic chokepoints and infrastructures in ungoverned spaces; as well as in territorial and extra-territorial border disputes. In addition, some form of peace enforcement is probably necessary in risk conditions pertaining to: extremism of marginalised groups; potential disputes over previously uninhabited and resource-rich territories; and interstate rivalry. Furthermore, this research finds that peacekeeping measures will be feasible and necessary in at least risk conditions pertaining to: potential spillover of ethnic, religious, ideological conflict; uncontrolled migration; consequences from environmental catastrophes or changes; territorial and extra-territorial border disputes; and potential disputes over previously uninhabited and resource-rich territories. These findings are all subject to both generic and case specific preconditions that must exist for a peace support operation. Some deductions could be derived from the research findings. Although some risk conditions may appear illogical, understanding the underlying logic of a conflict is fundamental to understanding transition in crisis management. Practitioners of crisis management should possess cognizance of such transition. They must understand how transition should occur from threat to safety, from conflict to stability – and so forth. Understanding transition is imperative for managing the dynamic evolution of preconditions, which begins at the outset of a peace support operation. Furthermore, it is pertinent that spoilers are defined from a peace process point of view. If spoilers are defined otherwise, it changes the nature of an operation towards war, where the logic is breaking the will of an enemy - and surrender. In peace support operations, the logic is different: actions towards spoilers are intended to cause transition towards consent - not defeat. Notwithstanding future developments, history continues to provide strategic education. However, the distinction is that the risk conditions occur in novel futures. Hence, lessons learned from the past should be fitted to the case at hand. This research shows compelling evidence that swaying between intervention optimism and pessimism is not substantiated. Both peace enforcement and peacekeeping are sine qua non for successful military crisis management in the next decade.

Synthesis of percarboxylic acids in microreactor

Percarboxylic acids are commonly used as disinfection and bleaching agents in textile, paper, and fine chemical industries. All of these applications are based on the oxidative potential of these compounds. In spite of high interest in these chemicals, they are unstable and explosive chemicals, which increase the risk of synthesis processes and transportation. Therefore, the safety criteria in the production process should be considered. Microreactors represent a technology that efficiently utilizes safety advantages resulting from small scale. Therefore, microreactor technology was used in the synthesis of peracetic acid and performic acid. These percarboxylic acids were produced at different temperatures, residence times and catalyst i.e. sulfuric acid concentrations. Both synthesis reactions seemed to be rather fast because with performic acid equilibrium was reached in 4 min at 313 K and with peracetic acid in 10 min at 343 K. In addition, the experimental results were used to study the kinetics of the formation of performic acid and peracetic acid. The advantages of the microreactors in this study were the efficient temperature control even in very exothermic reaction and good mixing due to the short diffusion distances. Therefore, reaction rates were determined with high accuracy. Three different models were considered in order to estimate the kinetic parameters such as reaction rate constants and activation energies. From these three models, the laminar flow model with radial velocity distribution gave most precise parameters. However, sulfuric acid creates many drawbacks in this synthesis process. Therefore, a ´´greener´´ way to use heterogeneous catalyst in the synthesis of performic acid in microreactor was studied. The cation exchange resin, Dowex 50 Wx8, presented very high activity and a long life time in this reaction. In the presence of this catalyst, the equilibrium was reached in 120 second at 313 K which indicates a rather fast reaction. In addition, the safety advantages of microreactors were investigated in this study. Four different conventional methods were used. Production of peracetic acid was used as a test case, and the safety of one conventional batch process was compared with an on-site continuous microprocess. It was found that the conventional methods for the analysis of process safety might not be reliable and adequate for radically novel technology, such as microreactors. This is understandable because the conventional methods are partly based on experience, which is very limited in connection with totally novel technology. Therefore, one checklist-based method was developed to study the safety of intensified and novel processes at the early stage of process development. The checklist was formulated using the concept of layers of protection for a chemical process. The traditional and three intensified processes of hydrogen peroxide synthesis were selected as test cases. With these real cases, it was shown that several positive and negative effects on safety can be detected in process intensification. The general claim that safety is always improved by process intensification was questioned.

Simulation of Solid Processes by Aspen Plus

Solid processes are used for obtaining the valuable minerals. Due to their worth, it is obligatory to perform different experiments to determine the different values of these minerals. With the passage of time, it is becoming more difficult to carry out these experiments for each mineral for different characteristics due to high labor costs and consumption of time. Therefore, scientists and engineers have tried to overcome this issue. They made different software to handle this problem. Aspen is one of those software for the calculation of different parameters. Therefore, the aim of this report was to do simulation for solid processes to observe different effect for minerals. Different solid processes like crushing, screening; filtration and crystallization were simulated by Aspen Plus. The simulation results are obtained by using this simulation software and they are described in this thesis. It was noticed that the results were acceptable for all solid processes. Therefore, this software can be used for the designing of crushers by calculating the power consumption of crushers, can design the filter and for the calculation of material balance for all processes.

Evaluation of protein extraction methods to obtain protein concentrate from cassava leaf

The cassava leaf, waste generated in the harvest of the roots, is characterized by high content of protein, vitamins and minerals; however, its use is limited due to the high fiber content and antinutritional substances, which can be removed by obtaining protein concentrates. In this context, the objective of this study was to evaluate protein extraction processes, aiming the use of cassava leaves (Manihot esculenta Crantz) as an alternative protein. Four methods were tested: 1) Coagulation of Proteins by Lowering the Temperature, 2) Extraction by Isoelectric Precipitation, 3) Solubilization of Proteins and 4) Fermentation of Filter Leaf Juice. To obtain the concentrates, the use of fresh or dried leaves and extraction in one or two steps were also evaluated. The solubilization of proteins (method 3) showed a higher extraction yield; however, with concentrate of low quality. The fermentation of the juice (method 4) produced concentrates with higher quality and lower costs and the isoelectric precipitation (method 2) promoted the obtention of concentrates in less time, both with good prospects for use. The use of two extraction steps was not advantageous to the process and there was no difference between the use of fresh or dried leaf, and the use of fresh leaves is presented as a good option for the simplicity of the method.

Partisaanisodasta alueelliseen puolustusjärjestelmään : jugoslavialaisen sotataidollisen ajattelun kehittyminen toisen maailmansodan jälkeen

Väitöskirjan tavoitteena on ollut rakentaa kokonaiskuva aiheesta Jugoslavialaisen sotataidollisen ajattelun kehittyminen toisen maailmansodan jälkeen. Tutkimuksessa ei ole rajoituttu ainoastaan kuvailemaan sotataidollisen ajattelun kehittyminen, vaan on pyritty selvittämään kehittymiseen vaikuttaneet tekijät ja vastaamaan kysymykseen, miksi näin on tapahtunut? Aiemmat länsimaiset tutkimukset ovat tarkastelleet jugoslavialaista sotataitoa tai maanpuolustusta vain jostain tietystä rajallisesta näkökulmasta, kuten esimerkiksi Jugoslavian kansanarmeijaa, asevoimien vaikutusta maan poliittiseen elämään tai sotilaallista doktriinia koskien. Sotataidon kehittymiseen vaikuttavat tekijät huomioivaa kokonaisesitystä ole tehty. Myös jugoslavialainen sotataidollinen ajattelu on jäänyt pääosin pimentoon. Jugoslavialainen maan sotataitoon kohdistunut tutkimus on ollut laajaa ja monipuolista, mutta sen käytettävyyteen osittain vaikuttaa marxilais-leniniläinen materialistis-dialektinen, historialliseen materialismiin perustuva tutkimusmenetelmä. Väitöskirjan päätutkimusaineiston ovat muodostaneet alkuperäislähteet, ensisijaisesti jugoslavialaiset ohjesäännöt, käsikirjat, oppaat ja oppikirjat. Muu lähteistö on koostunut lähinnä arkistoasiakirjoista ja muusta kirjallisuudesta. Tutkimusmenetelmä on ollut historiatieteellinen käsittäen muun muassa ulkoisen ja sisäisen lähdekritiikin harjoittamisen, tietojen varmistamisen mahdollisimman useasta toisistaan riippumattomasta lähteestä sekä pyrkimyksen rekonstruoida ristiriidaton kokonaiskuva tutkimuskohteesta. Eri lähteistä ja lähderyhmistä saatuja tietoja on vertailtu, analysoitu sekä yhdistetty kriittisesti. Lähteiden käytettävyyden, lähdearvon ja luotettavuuden arviointi ovat olleet merkittävässä roolissa, näistä kaikista tärkeimpänä luotettavuuden arviointi. Sisäisen ja ulkoisen lähdekritiikin keinoin on pyritty luomaan oma ristiriidaton tulkinta kokonaisuudesta, jugoslavialaisen sotataidollisen ajattelun kehittymisestä toisen maailmansodan jälkeen. Tutkimuksessa on pitäydytty niin pitkälle kuin mahdollista jugoslavialaisen sotataidon alkuperäisessä terminologiassa. Jugoslavialaisia termejä ei ole muokattu vastaamaan paremmin esimerkiksi tällä hetkellä länsimaisessa sotataidossa käytettyjä käsitteitä. Väitöskirjan rakenne on temaattinen. Läpi koko tutkittavan ajanjakson jugoslavialaisen sotataidollisen ajattelun kehittymisessä on tunnistettavissa samat määräävät tekijät: historialliset taustatekijät, sotilaallinen uhka, sotilaallinen doktriini, lakiperusteet, kommunistiliiton ohjaus ja asevoimien sekä yhteiskunnan valmiuden kehittyminen. Jugoslaviassa puhuttiin aseelliseen kamppailuun vaikuttavista sodankäynnin faktoreista, joita olivat yhteiskunnalliset tekijät, materiaalis-tekniset tekijät ja sotilaalliset tekijät. Kaikista tärkeimpänä tekijänä pidettiin kuitenkin ihmistä itseään, vaikka ihmisen merkitys välillä tuntuikin hukkuvan ”moraalis-poliittiset tekijät”-sanahirviön alle. Tutkimuskysymyksiin on vastattu sotataitoon vaikuttaneiden edellä mainittujen tekijöiden kautta. Kuhunkin muutostekijään liittyvä kehitys on kuvattu kronologisena esityksenä. Kansan vapautussodassa vuosina 1941–1945 perustettujen partisaaniyksiköiden muodostamisessa sekä niiden toimintamenetelmissä on havaittavissa runsaasti yhtymäkohtia 1700- ja 1800-luvun hajdukkijoukkojen sekä 1800-luvun lopun ja 1900-luvun alun četnikkijoukkojen vastaaviin periaatteisiin. Samankaltaisuuksia ilmenee 1950-luvulta alkaen alueellisen puolustuksen joukkojen ja partisaaniyksiköiden toimintamenetelmien yhteydessä väliaikaisesti menetetyllä alueella toimittaessa. Kansan tukeen, karismaattisiin johtajiin ja yllätyselementtiin perustuva sissitoiminta on perinteistä eteläslaavilaista sotataitoa. Sodanjälkeinen jugoslavialainen sotataito oli jatkumoa eteläslaavien vuosisatoja vanhalle sotataidolliselle perinteelle, vaikka sitä ei julkisesti Jugoslaviassa muutamia poikkeuksia lukuun ottamatta myönnettykään. Jugoslavian sotilaallinen doktriini oli luotu kaikista suunnista kohdistuvia hyökkäyksiä vastaan, mutta sotilaallisen uhkan painotukset vaihtelivat usein, jopa vain muutaman vuoden välein. Tämä ei johtunut päättämättömyydestä eikä pelkästään koetun uhkan suunnan vaihtumisesta. Painottamalla sisäisen ja ulkoisen uhkan jatkuvuutta sekä uhkan suunnan vaihtelua pyrittiin pitämään maanpuolustuspiirit valppaina ja kansalaiset aktiivisina. Tällä tavalla myös perusteltiin maanpuolustuksen korkeita kustannuksia ja ennen kaikkea pyrittiin lisäämään maan sisäistä veljeyttä ja yhtenäisyyttä. On ilmeistä, että sekä lännestä että idästä kohdistui Jugoslavian suuntaan suurta poliittista ja sotilaallista intressiä kylmän sodan vuosina 1945–1990, mutta suoran sotilaallisen uhkan aukoton todistaminen olisi kuitenkin hankalaa. Oleellista onkin jugoslavialaisten oma käsitys maataan vastaan kohdistuneesta sotilaallisesta uhkasta. Sisäisen uhkan vaikutus alkoi kasvaa 1970-luvun alkupuolelta lähtien ja se johti lopulta 1980-luvulla alueellisen puolustuksen joukkojen esikuntien lakkauttamiseen ja taisteluvälineiden hajavarastointijärjestelmän purkamiseen. Yhteiskunnallisista tekijöistä merkittävimpinä sotataitoon ja sotataidolliseen ajatteluun vaikuttaneina osina olivat lait ja Jugoslavian kommunistiliitto. Perustuslakiin ja lakiin kansallisesta puolustuksesta sekä kommunistiliiton päätöslauselmiin sisällytetyt vaatimukset sotataidon kehittymiselle kuitenkin vain toistivat sotilaallisessa doktriinissa määritettyjä suuntaviivoja sekä määräyksiä. Maanpuolustukseen liittyneiden määräysten ja ohjeiden hyväksymiselle laillisen järjestyksen mukaisesti annettiin kuitenkin erittäin suuri arvo. Niiden toimeenpanon leviäminen maanlaajuisesti varmistettiin puolueen päätöksillä velvoittamalla muun muassa kommunistiliiton paikallisorganisaatiot, puoluesolut asevoimien sisällä sekä kaikki liittovaltion hallintotasot tekemään kaikkensa yleisen kansanpuolustuksen ja sitä ilmentävän sotataidon toteutumisen eteen. Materiaalis-teknisen tekijän kokonaisuus sisälsi aseet ja varusteet sekä niihin liittyviä muita seikkoja, kuten yhteiskunnan teollisuuden kehittymisen asteen sekä kyvyn suojautua vihollisen taisteluvälineitä vastaan ja luoda vihollisen aseita vastaan tehokkaampi vasta-ase. Siihen luettiin myös yksilöiden, taktisten ja yhdistettyjen taktisten yksiköiden sekä koko kansan koulutus aseiden ja varusteiden tarkoituksenmukaiseen käyttöön. Vaikka jugoslavialainen aseteollisuus kehittyi tutkimusperiodin aikana voimakkaasti, joutui maa taloudellisten resurssiensa rajallisuuden ja mahdollisen vihollishyökkäyksen ylivoimaisuuden havaittuaan toteamaan, että maanpuolustuksen ongelmia ei voida ratkaista materiaalin ja tekniikan määrällä tai laadulla. Ratkaisun oli löydyttävä sotilaallisista tekijöistä ja varsinkin sotataidosta. Sotilaalliset tekijät ja prosessit olivat jugoslavialaisen sotataidon ja sotataidollisen ajattelun kehittymisen kannalta tärkein muutostekijä. Sotilaallisten tekijöiden ytimen muodosti sotataito, joka Jugoslaviassa koostui teoriasta ja käytännöstä. Tämä jako koski sotataidon kolmea tasoa: strategiaa, operatiikkaa ja taktiikkaa. Sotataitoon kuuluvina osina pidettiin muun muassa taisteluvalmiutta, liikekannallepanovalmiutta, yhteiskunnallis-poliittisten yhteisöjen aseetonta vastarintaa, aseellisen kamppailun operatiivista ja taktista tasoa, materiaalista ja teknistä varustamista, sotatalouden valmistelujen organisointia sekä yhteiskunnallisia palveluja poikkeusoloissa. Osa näistä kuului edellä mainittuihin yhteiskunnallisiin tai materiaalis-teknisiin tekijöihin. Jugoslavialainen sotataito onkin nähtävä matriisinomaisena kokonaisuutena, jossa sotataidon kolmeen toiminnalliseen tasoon, strategiaan, operatiikkaan ja taktiikkaan vaikuttivat historialliset taustatekijät, sotilaallinen uhka, yhteiskunnalliset tekijät ja materiaalis-tekniset tekijät. Jugoslavialaisen sotataidon kokonaisuuteen kuului myös se, että mainitut muutostekijät vaikuttivat vielä toisiinsa. Lopputuloksena näin kokonaisvaltaisesta näkemyksestä sotataitoon ja sotataidolliseen ajatteluun Jugoslavia kykeni luomaan poikkeuksellisen tehokkaana pidetyn puolustusratkaisun, jossa koko yhteiskunnan kaikki resurssit pystyttiin suuntaamaan hyökkäyksen torjumiseen ja maahan tunkeutuneiden pois ajamiseen. Aiempi tutkimus on nähnyt jugoslavialaisen sotataidon kehittymisen keskeisimpänä vaikuttimena ja murroskohtana Varsovan liiton joukkojen toimeenpaneman Tšekkoslovakian miehityksen ja siitä seuranneen koetun uhkan merkittävän voimistumisen. Yleisen kansanpuolustuksen doktriiniin liittyvä taustatutkimus, teorianmuodostus ja doktriinin käyttöönotto tapahtuivat kuitenkin jo 1950-luvulla. Tšekkoslovakian miehitys toimi vain muutoksen toimeenpanoa vauhdittavana tekijänä. Jugoslavialaiset korostivat, että jugoslavialaisessa yhteiskunnassa keskeisessä asemassa ollut yhteisjohtoisuuden periaate ulottui myös maanpuolustukseen ja sotataitoon. Tutkimusaineistoon perehtyminen kuitenkin osoitti, että yleisen kansanpuolustuksen kokonaisuutta kuvaavat oppikirjat, laeissa asetetut määräykset ja Jugoslavian kommunistiliiton julkaisemat vaatimukset eivät olleet jalkautuneet sotataidon teoriaan tai käytäntöön operatiivisella tai taktisella tasolla. Strategisella tasolla yhteisjohtoisuus esiintyi näkyvämmin vain sotilaallisen konseptin ja strategian yhteydessä. Sotilaallisen doktriinin osalta yhteisjohtoisuus ilmeni lähinnä kahdessa asiassa. Alueellisen puolustuksen yksiköiden varustamisvelvoite oli asetettu siviilihallinnon eri tasojen vastuulle. Alueellisen puolustuksen esikunnat ja komentajat olivat vastuussa yleisen kansanpuolustuksen ja yhteiskunnallisen itsesuojelun komiteoille. Siviilihallinnon organisaatioiden kyky varustaa alueellisen puolustuksen yksiköt osoittautui kuitenkin heikoksi. Alueellisen puolustuksen esikunnatkin toimivat upseereiden johtamina sotilaallisina johtoportaina, ja yleisen kansanpuolustuksen ja yhteiskunnallisen itsesuojelun komiteoiden toiminta komentajien ja esikuntien suuntaan rajoittui vain nimelliseen ohjaukseen. Yhteisjohtoisuus osoittautuikin tutkimuksen kuluessa piirteeksi, joka julkisesta retoriikasta huolimatta ei toteutunut jugoslavialaisessa sotataidon praktiikassa. Jugoslavialaisen sotataidollisen ajattelun kehittymisen kaari käynnistyi partisaanisodasta ja päätyi alueelliseen puolustusjärjestelmään. Kansakunta ja sen useat eri kansallisuudet onnistuivat luomaan tieteelliseen ja tutkittuun tietoon perustuvan välineen, sotataidon teorian ja käytännön, joka suojeli maata yli puolen vuosisadan ajan. Yleinen kansanpuolustus sekä jugoslavialainen sotataito ovat toisiensa synonyymejä, seurauksia ja synnyttäjiä. Puolustusratkaisu lähti omista kansallisista lähtökohdista, siihen sulautettiin valikoiden ja jalostettuna hyviksi sekä menestyksekkäiksi koettuja ulkomaisia elementtejä sekä vaikutteita. Sitä perusteltiin monipuolisilla poliittisilla, ideologisilla, teoreettisilla, historiallisilla sekä nykyaikaisilla sotataidollisilla argumenteilla, mutta kaikesta tästä huolimatta sen ydin oli omintakeinen jugoslavialainen sotataidollinen ajattelu.

Improvement of open innovation processes: case Nokia

Open innovation is becoming increasingly popular in academic literature and in business life, but even if people heard about it, they might not understand what it really is, they may over-estimate it thinking that it is savior or underestimate it, concentrating on limitations and risks. Current work sheds light on most important concepts of open innovation theory. Goal of current research is to offer business processes improvement for both inbound and outbound modes in case company. It is relevant as open innovation proved to affect firms‘ performance in general case and in case company, and Nokia planned to develop open innovation implementation since 2008 but still competitors succeed in it more, therefore analysis of current situation with open innovation in Nokia and recommendations how to improve it are topical. Case study method was used to answer the question ―How open innovation processes can be improved?‖. 11 in-depth interviews with Nokia senior managers and independent consultants were used to reach the goal of the thesis, as well as secondary sources. Results of current work are as-is and to-be models (process models of today and best practices models) of several open innovation modes, and recommendation for case company, which will be presented to company representatives and checked for practical applicability.
