Does absorptive capacity determine collaborative research returns to innovation? A geographical dimension

This paper aims to estimate the impact of research collaboration with partners in different geographical areas on innovative performance. By using the Spanish Technological Innovation Panel, this study provides evidence that the benefits of research collaboration differ across different dimensions of the geography. We find that the impact of extra-European cooperation on innovation performance is larger than that of national and European cooperation, indicating that firms tend to benefit more from interaction with international partners as a way to access new technologies or specialized and novel knowledge that they are unable to find locally. We also find evidence of the positive role played by absorptive capacity, concluding that it implies a higher premium on the innovation returns to cooperation in the international case and mainly in the European one.

From Regional Landslide Detection to Site-Specific Slope Deformation Monitoring and Modelling Based on Active Remote Sensors

Landslide processes can have direct and indirect consequences affecting human lives and activities. In order to improve landslide risk management procedures, this PhD thesis aims to investigate capabilities of active LiDAR and RaDAR sensors for landslides detection and characterization at regional scales, spatial risk assessment over large areas and slope instabilities monitoring and modelling at site-specific scales. At regional scales, we first demonstrated recent boat-based mobile LiDAR capabilities to model topography of the Normand coastal cliffs. By comparing annual acquisitions, we validated as well our approach to detect surface changes and thus map rock collapses, landslides and toe erosions affecting the shoreline at a county scale. Then, we applied a spaceborne InSAR approach to detect large slope instabilities in Argentina. Based on both phase and amplitude RaDAR signals, we extracted decisive information to detect, characterize and monitor two unknown extremely slow landslides, and to quantify water level variations of an involved close dam reservoir. Finally, advanced investigations on fragmental rockfall risk assessment were conducted along roads of the Val de Bagnes, by improving approaches of the Slope Angle Distribution and the FlowR software. Therefore, both rock-mass-failure susceptibilities and relative frequencies of block propagations were assessed and rockfall hazard and risk maps could be established at the valley scale. At slope-specific scales, in the Swiss Alps, we first integrated ground-based InSAR and terrestrial LiDAR acquisitions to map, monitor and model the Perraire rock slope deformation. By interpreting both methods individually and originally integrated as well, we therefore delimited the rockslide borders, computed volumes and highlighted non-uniform translational displacements along a wedge failure surface. Finally, we studied specific requirements and practical issues experimented on early warning systems of some of the most studied landslides worldwide. As a result, we highlighted valuable key recommendations to design new reliable systems; in addition, we also underlined conceptual issues that must be solved to improve current procedures. To sum up, the diversity of experimented situations brought an extensive experience that revealed the potential and limitations of both methods and highlighted as well the necessity of their complementary and integrated uses.

Human Capital Composition and Economic Growth at a Regional Level

With this paper we build a two-region model where both innovation and imitation are performed. In particular imitation takes the form of technological spillovers that lagging regions may exploit given certain human capital conditions. We show how the high skill content of each region’s workforce (rather than the average human capital stock) is crucial to determine convergence towards the income level of the leader region and to exploit the technological spillovers coming from the frontier. The same applies to bureaucratic/institutional quality which are conductive to higher growth in the long run. We test successfully our theoretical result over Spanish regions for the period between 1960 and 1997. We exploit system GMM estimators which allow us to correctly deal with endogeneity problems and small sample bias.

Factors explaining urban transport systems in large European cities: A cross-sectional approach

The paper analyses the link between human capital and regional economic growth in the European Union. Using different indicat The importance of effective and efficient mobility in large cities is becoming essential for planners and citizens due to its impact in terms of social, economic and geographic development. The aim of this research is to determine factors explaining urban transport systems by estimating aggregate supply and demand equations for 45 large European cities. Supply and Demand equations are separately and jointly determined using OLS and SUR estimation models. On one hand, our findings suggest the importance of economic variables on the supply of public transport. On the other, we highlight the role of those factors influencing the generalized cost of transport as main drivers of demand for public transit. Additionally, regional variables are introduced to capture institutional heterogeneity in this service, and we find that regional patterns are powerful explanatory determinants of urban transportation systems in Europe.

Do innovation and human capital explain the productivity gap between small and large firms?

Empirical evidence is compelling that large firms are more productive than small firms. The hypothesis in this paper is that the productivity differences between small and large firms are associated with two of the main determinants of a firm’s performance: the human and technological capital that firms incorporate. We suggest that the contribution of these factors in explaining the productivity-size gap might not only be due to the fact that large firms make a more extensive use of them, but also because large firms obtain higher returns from their investment in human and technological capital. The evidence we obtain for a comprehensive sample of Spanish manufacturing firms (1990-2002) supports this hypothesis, which has important implications for the effectiveness of policies designed to improve productivity in SMEs by stimulating innovation and the use of more skilled workers.

Referência geoquímica regional para a interpretação das concentrações de elementos químicos nos sedimentos da bacia do Lago Paranoá - DF

The present study aimed at determining a regional geochemical reference for sediment samples from Lago Paranoá watershed through the formulation of geoaccumulation indexes. The need for obtaining information from areas representing low human impact was the basis of this work. Systematic evaluations of sediment from Lago Paranoá will bring valuable information regarding the potential risk that this layer represents for aquatic organisms. Thus, despite the recent water quality improvements achieved in this ecosystem, contaminants incorporated in the sediments may be remobilized for alterations in the adjacent environment. The adsorption capacity of chemical elements in sediment samples was controlled through the variation in the amounts of organic matter, the mineralogical composition and the granulometric variation. By creating the Sediment Enrichment Index (SEI) through the normalization of analytical data it was possible to establish the magnitude of this enrichment relatively to naturally occurring concentrations all over the region of interest. Normalized values with organic matter were especially useful for the evaluation of lothic systems.

Maritime Safety in the Gulf of Finland. Review on Policy Instruments

Suomenlahden lisääntynyt meriliikenne on herättänyt huolta meriliikenteen turvallisuuden tasosta, ja erityisesti Venäjän öljyviennin kasvu on lisännyt öljyonnettomuuden todennäköisyyttä Suomenlahdella. Erilaiset kansainväliset, alueelliset ja kansalliset ohjauskeinot pyrkivät vähentämään merionnettomuuden riskiä ja meriliikenteen muita haittavaikutuksia. Tämä raportti käsittelee meriturvallisuuden yhteiskunnallisia ohjauskeinoja: ohjauskeinoja yleisellä tasolla, meriturvallisuuden keskeisimpiä säätelijöitä, meriturvallisuuden ohjauskeinoja ja meriturvallisuuspolitiikan tulevaisuuden näkymiä, ohjauskeinojen tehokkuutta ja nykyisen meriturvallisuuden ohjausjärjestelmän heikkouksia. Raportti on kirjallisuuskatsaus meriturvallisuuden yhteiskunnalliseen sääntelyn rakenteeseen ja tilaan erityisesti Suomenlahden meriliikenteen näkökulmasta. Raportti on osa tutkimusprojektia ”SAFGOF - Suomenlahden meriliikenteen kasvunäkymät 2007 - 2015 ja kasvun vaikutukset ympäristölle ja kuljetusketjujen toimintaan” ja sen työpakettia 6 ”Keskeisimmät riskit ja yhteiskunnalliset vaikutuskeinot”. Yhteiskunnalliset ohjauskeinot voidaan ryhmitellä hallinnollisiin, taloudellisiin ja tietoohjaukseen perustuviin ohjauskeinoihin. Meriturvallisuuden edistämisessä käytetään kaikkia näitä, mutta hallinnolliset ohjauskeinot ovat tärkeimmässä asemassa. Merenkulun kansainvälisen luonteen vuoksi meriturvallisuuden sääntely tapahtuu pääosin kansainvälisellä tasolla YK:n ja erityisesti Kansainvälisen merenkulkujärjestön (IMO) toimesta. Lisäksi myös Euroopan Unionilla on omaa meriturvallisuuteen liittyvää sääntelyä ja on myös olemassa muita alueellisia meriturvallisuuden edistämiseen liittyviä elimiä kuten HELCOM. Joitakin meriturvallisuuden osa-alueita säädellään myös kansallisella tasolla. Hallinnolliset meriturvallisuuden ohjauskeinot sisältävät aluksen rakenteisiin ja varustukseen, alusten kunnon valvontaan, merimiehiin ja merityön tekemiseen sekä navigointiin liittyviä ohjauskeinoja. Taloudellisiin ohjauskeinoihin kuuluvat esimerkiksi väylä- ja satamamaksut, merivakuutukset, P&I klubit, vastuullisuus- ja korvauskysymykset sekä taloudelliset kannustimet. Taloudellisten ohjauskeinojen käyttö meriturvallisuuden edistämiseen on melko vähäistä verrattuna hallinnollisten ohjauskeinojen käyttöön, mutta niitä voitaisiin varmasti käyttää enemmänkin. Ongelmana taloudellisten ohjauskeinojen käytössä on se, että ne kuuluvat pitkälti kansallisen sääntelyn piiriin, joten alueellisten tai kansainvälisten intressien edistäminen taloudellisilla ohjauskeinoilla voi olla hankalaa. Tieto-ohjaus perustuu toimijoiden vapaaehtoisuuteen ja yleisen tiedotuksen lisäksi tieto-ohjaukseen sisältyy esimerkiksi vapaaehtoinen koulutus, sertifiointi tai meriturvallisuuden edistämiseen tähtäävät palkinnot. Poliittisella tasolla meriliikenteen aiheuttamat turvallisuusriskit Suomenlahdella on otettu vakavasti ja paljon työtä tehdään eri tahoilla riskien minimoimiseksi. Uutta sääntelyä on odotettavissa etenkin liittyen meriliikenteen ympäristövaikutuksiin ja meriliikenteen ohjaukseen kuten meriliikenteen sähköisiin seurantajärjestelmiin. Myös inhimilliseen tekijän merkitykseen meriturvallisuuden kehittämisessä on kiinnitetty lisääntyvissä määrin huomiota, mutta inhimilliseen tekijän osalta tehokkaiden ohjauskeinojen kehittäminen näyttää olevan haasteellista. Yleisimmin lääkkeeksi esitetään koulutuksen kehittämistä. Kirjallisuudessa esitettyjen kriteereiden mukaan tehokkaiden ohjauskeinojen tulisi täyttää seuraavat vaatimukset: 1) tarkoituksenmukaisuus – ohjauskeinojen täytyy olla sopivia asetetun tavoitteen saavuttamiseen, 2) taloudellinen tehokkuus – ohjauskeinon hyödyt vs. kustannukset tulisi olla tasapainossa, 3) hyväksyttävyys – ohjauskeinon täytyy olla hyväksyttävä asianosaisten ja myös laajemman yhteiskunnan näkökulmasta katsottuna, 4) toimeenpano – ohjauskeinon toimeenpanon pitää olla mahdollista ja sen noudattamista täytyy pystyä valvomaan, 5) lateraaliset vaikutukset – hyvällä ohjauskeinolla on positiivisia seurannaisvaikutuksia muutoinkin kuin vain ohjauskeinon ensisijaisten tavoitteiden saavuttaminen, 6) kannustin ja uuden luominen – hyvä ohjauskeino kannustaa kokeilemaan uusia ratkaisuja ja kehittämään toimintaa. Meriturvallisuutta koskevaa sääntelyä on paljon ja yleisesti ottaen merionnettomuuksien lukumäärä on ollut laskeva viime vuosikymmenien aikana. Suuri osa sääntelystä on ollut tehokasta ja parantanut turvallisuuden tasoa maailman merillä. Silti merionnettomuuksia ja muita vaarallisia tapahtumia sattuu edelleen. Nykyistä sääntelyjärjestelmää voidaan kritisoida monen asian suhteen. Kansainvälisen sääntelyn aikaansaaminen ei ole helppoa: prosessi on yleensä hidas ja tuloksena voi olla kompromissien kompromissi. Kansainvälinen sääntely on yleensä reaktiivista eli ongelmakohtiin puututaan vasta kun jokin onnettomuus tapahtuu sen sijaan että se olisi proaktiivista ja pyrkisi puuttumaan ongelmakohtiin jo ennen kuin jotain tapahtuu. IMO:n työskentely perustuu kansallisvaltioiden osallistumiseen ja sääntelyn toimeenpano tapahtuu lippuvaltioiden toimesta. Kansallisvaltiot ajavat IMO:ssa pääasiallisesti omia intressejään ja sääntelyn toimeenpanossa on suuria eroja lippuvaltioiden välillä. IMO:n kyvyttömyys puuttua havaittuihin ongelmiin nopeasti ja ottaa sääntelyssä huomioon paikallisia olosuhteita on johtanut siihen, että esimerkiksi Euroopan Unioni on alkanut itse säädellä meriturvallisuutta ja että on olemassa sellaisia alueellisia erityisjärjestelyjä kuin PSSA (particularly sensitive sea area – erityisen herkkä merialue). Merenkulkualalla toimii monenlaisia yrityksiä: toisaalta yrityksiä, jotka pyrkivät toimimaan turvallisesti ja kehittämään turvallisuutta vielä korkeammalle tasolle, ja toisaalta yrityksiä, jotka toimivat niin halvalla kuin mahdollista, eivät välitä turvallisuusseikoista, ja joilla usein on monimutkaiset ja epämääräiset omistusolosuhteet ja joita vahingon sattuessa on vaikea saada vastuuseen. Ongelma on, että kansainvälisellä merenkulkualalla kaikkien yritysten on toimittava samoilla markkinoilla. Vastuuttomien yritysten toiminnan mahdollistavat laivaajat ja muut alan toimijat, jotka suostuvat tekemään yhteistyötä niiden kanssa. Välinpitämätön suhtautuminen turvallisuuteen johtuu osaksi myös merenkulun vanhoillisesta turvallisuuskulttuurista. Verrattaessa meriturvallisuuden sääntelyjärjestelmää kokonaisuutena tehokkaiden ohjauskeinoihin kriteereihin, voidaan todeta, että monien kriteerien osalta nykyistä järjestelmää voidaan pitää tehokkaana ja onnistuneena. Suurimmat ongelmat lienevät sääntelyn toimeenpanossa ja ohjauskeinojen kustannustehokkuudessa. Lippuvaltioiden toimeenpanoon perustuva järjestelmä ei toimi toivotulla tavalla, josta mukavuuslippujen olemassa olo on selvin merkki. Ohjauskeinojen, sekä yksittäisten ohjauskeinojen että vertailtaessa eri ohjauskeinoja keskenään, kustannustehokkuutta on usein vaikea arvioida, minkä seurauksena ohjauskeinojen kustannustehokkuudesta ei ole saatavissa luotettavaa tietoa ja tuloksena voi olla, että ohjauskeino on käytännössä pienen riskin eliminoimista korkealla kustannuksella. Kansainvälisen tason meriturvallisuus- (ja merenkulku-) politiikan menettelytavoiksi on ehdotettu myös muita vaihtoehtoja kuin nykyinen järjestelmä, esimerkiksi monitasoista tai polysentristä hallintojärjestelmää. Monitasoisella hallintojärjestelmällä tarkoitetaan järjestelmää, jossa keskushallinto on hajautettu sekä vertikaalisesti alueellisille tasoille että horisontaalisesti ei-valtiollisille toimijoille. Polysentrinen hallintojärjestelmä menee vielä askeleen pidemmälle. Polysentrinen hallintojärjestelmä on hallintotapa, jonka puitteissa kaikentyyppiset toimijat, sekä yksityiset että julkiset, voivat osallistua hallintoon, siis esimerkiksi hallitukset, edunvalvontajärjestöt, kaupalliset yritykset jne. Kansainvälinen lainsäädäntö määrittelee yleiset tasot, mutta konkreettiset toimenpiteet voidaan päättää paikallisella tasolla eri toimijoiden välisessä yhteistyössä. Tämän tyyppisissä hallintojärjestelmissä merenkulkualan todellinen, kansainvälinen mutta toisaalta paikallinen, toimintaympäristö tulisi otetuksi paremmin huomioon kuin järjestelmässä, joka perustuu kansallisvaltioiden keskenään yhteistyössä tekemään sääntelyyn. Tällainen muutos meriturvallisuuden hallinnassa vaatisi kuitenkin suurta periaatteellista suunnanmuutosta, jollaisen toteutumista ei voi pitää kovin todennäköisenä ainakaan lyhyellä tähtäimellä.

Innovation and Internationalisation in Russian Companies: Challenges and Opportunities for Open Innovation and Cooperation

Increasing globalisation and intensified cross-border cooperation, together with significant technological breakthroughs, create a fascinating gap for the research of the relationship between internationalisation and innovation on national, regional and company levels in Russia. The intensified international trade between countries and regions benefited from favourable institutional conditions, and facilitated the technology transfer and the development of innovations on the national level. This study approaches the same question from the company perspective; if certain companies are more innovative than other domestic companies, will they start internationalisation more easily or get involved in cooperation with international stakeholders? When companies operate in international markets, how do they obtain knowledge? Moreover, would this new knowledge from the foreign market help then to increase innovativeness, competitiveness and develop operations in domestic/local and foreign markets? Considering the role of foreign direct investments (FDI), the research in hand tries to find out the role of companies with FDI on the other players on the home market. Do foreigners bring new technology, innovation to the country? Is there spillover effect observed and how local companies can benefit from them? This dissertation studies the internationalisation and innovation in Russian companies, both from the outward internationalisation and inward internationalisation perspectives. Russian companies developed quickly during the transition period, after the dissolution of the Soviet Union. The common background of these companies, the effects of the change of ownership, and some managerial difficulties make them more sensitive to competitions issues, and in this context, the opportunities brought by the developing innovations are seen in companies and on the governmental level.

Structural and operational optimisation : applications in energy systems

In this work mathematical programming models for structural and operational optimisation of energy systems are developed and applied to a selection of energy technology problems. The studied cases are taken from industrial processes and from large regional energy distribution systems. The models are based on Mixed Integer Linear Programming (MILP), Mixed Integer Non-Linear Programming (MINLP) and on a hybrid approach of a combination of Non-Linear Programming (NLP) and Genetic Algorithms (GA). The optimisation of the structure and operation of energy systems in urban regions is treated in the work. Firstly, distributed energy systems (DES) with different energy conversion units and annual variations of consumer heating and electricity demands are considered. Secondly, district cooling systems (DCS) with cooling demands for a large number of consumers are studied, with respect to a long term planning perspective regarding to given predictions of the consumer cooling demand development in a region. The work comprises also the development of applications for heat recovery systems (HRS), where paper machine dryer section HRS is taken as an illustrative example. The heat sources in these systems are moist air streams. Models are developed for different types of equipment price functions. The approach is based on partitioning of the overall temperature range of the system into a number of temperature intervals in order to take into account the strong nonlinearities due to condensation in the heat recovery exchangers. The influence of parameter variations on the solutions of heat recovery systems is analysed firstly by varying cost factors and secondly by varying process parameters. Point-optimal solutions by a fixed parameter approach are compared to robust solutions with given parameter variation ranges. In the work enhanced utilisation of excess heat in heat recovery systems with impingement drying, electricity generation with low grade excess heat and the use of absorption heat transformers to elevate a stream temperature above the excess heat temperature are also studied.

Innovation in a Non-Formal Adult Education Organisation – Multi-Case Study in Four Adult Education Centres

More than ever, education organisations are experiencing the need to develop new services and processes to satisfy expanding and changing customer needs and to adapt to the environmental changes and continually tightening economic situation. Innovation has been found in many studies to have a crucial role in the success of an organisation, both in the private and public sectors, in formal education and in manufacturing and services alike. However, studies concerning innovation in non-formal adult education organisations, such as adult education centres (AECs) in Finland, are still lacking. This study investigates innovation in the non-formal adult education organisation context from the perspective of organisational culture types and social networks. The objective is to determine the significant characteristics of an innovative non-formal adult education organisation. The analysis is based on data from interviews with the principals and fulltime staff of four case AECs. Before the case study, a pre-study phase is accomplished in order to obtain a preliminary understanding of innovation at AECs. The research found strong support for the need of innovation in AECs. Innovation is basically needed to accomplish the AEC system’s primary mission mentioned in the ACT on Liberal Adult Education. In addition, innovation is regarded vital to institutes and may prevent their decline. It helps the institutes to be more attractive, to enter new market, to increase customer satisfaction and to be on the cutting edge. Innovation is also seen as a solution to the shortage of resources. Innovative AECs search actively for additional resources for development work through project funding and subsidies, cooperation networks and creating a conversational and joyful atmosphere in the institute. The findings also suggest that the culture type that supports innovation at AECs is multidimensional, with an emphasis on the clan and adhocratic culture types and such values as: dynamism, future orientation, acquiring new resources, mistake tolerance, openness, flexibility, customer orientation, a risk-taking attitude, and community spirit. Active and creative internal and external cooperation also promote innovation at AECs. This study also suggests that the behaviour of a principal is crucial. The way he or she shows appreciation the staff, encouragement and support to the staff and his or her approachability and concrete participation in innovation activities have a strong effect on innovation attitudes and activities in AECs.

Thermal-Aware Networked Many-Core Systems

Advancements in IC processing technology has led to the innovation and growth happening in the consumer electronics sector and the evolution of the IT infrastructure supporting this exponential growth. One of the most difficult obstacles to this growth is the removal of large amount of heatgenerated by the processing and communicating nodes on the system. The scaling down of technology and the increase in power density is posing a direct and consequential effect on the rise in temperature. This has resulted in the increase in cooling budgets, and affects both the life-time reliability and performance of the system. Hence, reducing on-chip temperatures has become a major design concern for modern microprocessors. This dissertation addresses the thermal challenges at different levels for both 2D planer and 3D stacked systems. It proposes a self-timed thermal monitoring strategy based on the liberal use of on-chip thermal sensors. This makes use of noise variation tolerant and leakage current based thermal sensing for monitoring purposes. In order to study thermal management issues from early design stages, accurate thermal modeling and analysis at design time is essential. In this regard, spatial temperature profile of the global Cu nanowire for on-chip interconnects has been analyzed. It presents a 3D thermal model of a multicore system in order to investigate the effects of hotspots and the placement of silicon die layers, on the thermal performance of a modern ip-chip package. For a 3D stacked system, the primary design goal is to maximise the performance within the given power and thermal envelopes. Hence, a thermally efficient routing strategy for 3D NoC-Bus hybrid architectures has been proposed to mitigate on-chip temperatures by herding most of the switching activity to the die which is closer to heat sink. Finally, an exploration of various thermal-aware placement approaches for both the 2D and 3D stacked systems has been presented. Various thermal models have been developed and thermal control metrics have been extracted. An efficient thermal-aware application mapping algorithm for a 2D NoC has been presented. It has been shown that the proposed mapping algorithm reduces the effective area reeling under high temperatures when compared to the state of the art.

Achieving EU energy targets – Impacts of evolutionary and revolutionary transition paths on power systems

Ambitious energy targets set by EU put pressures to increase share of renewable electricity supply in this and next decades and therefore, some EU member countries have boosted increasing renewable energy generation capacity by implementing subsidy schemes on national level. In this study, two different change approaches to increase renewable energy supply and increase self-sufficiency of supply are assessed with respect to their impacts on power system, electricity market and electricity generation costs in Finland. It is obtained that the current electricity generation costs are high compared to opportunities of earnings from present-day investor’s perspective. In addition, the growth expectations of consumptions and the price forecasts do not stimulate investing in new generation capacity. Revolutionary transition path is driven by administrative and political interventions to achieve the energy targets. Evolutionary transition path is driven by market-based mechanisms, such as market itself and emission trading scheme. It is obtained in this study that in the revolutionary transition path operation of market-based mechanisms is distorted to some extent and it is likely that this path requires providing more public financial resources compared to evolutionary transition path. In the evolutionary transition path the energy targets are not achieved as quickly but market-based mechanisms function better and investment environment endures more stable compared to revolutionary transition path.

Biogas production in regional integrated biodegradable waste treatment – Possibilities for improving energy performance and reducing GHG emissions

The greatest threat that the biodegradable waste causes on the environment is the methane produced in landfills by the decomposition of this waste. The Landfill Directive (1999/31/EC) aims to reduce the landfilling of biodegradable waste. In Finland, 31% of biodegradable municipal waste ended up into landfills in 2012. The pressure of reducing disposing into landfills is greatly increased by the forthcoming landfill ban on biodegradable waste in Finland. There is a need to discuss the need for increasing the utilization of biodegradable waste in regional renewable energy production to utilize the waste in a way that allows the best possibilities to reduce GHG emissions. The objectives of the thesis are: (1) to find important factors affecting renewable energy recovery possibilities from biodegradable waste, (2) to determine the main factors affecting the GHG balance of biogas production system and how to improve it and (3) to find ways to define energy performance of biogas production systems and what affects it. According to the thesis, the most important factors affecting the regional renewable energy possibilities from biodegradable waste are: the amount of available feedstock, properties of feedstock, selected utilization technologies, demand of energy and material products and the economic situation of utilizing the feedstocks. The biogas production by anaerobic digestion was seen as the main technology for utilizing biodegradable waste in agriculturally dense areas. The main reason for this is that manure was seen as the main feedstock, and it can be best utilized with anaerobic digestion, which can produce renewable energy while maintaining the spreading of nutrients on arable land. Biogas plants should be located close to the heat demand that would be enough to receive the produced heat also in the summer months and located close to the agricultural area where the digestate could be utilized. Another option for biogas use is to upgrade it to biomethane, which would require a location close to the natural gas grid. The most attractive masses for biogas production are municipal and industrial biodegradable waste because of gate fees the plant receives from them can provide over 80% of the income. On the other hand, directing gate fee masses for small-scale biogas plants could make dispersed biogas production more economical. In addition, the combustion of dry agricultural waste such as straw would provide a greater energy amount than utilizing them by anaerobic digestion. The complete energy performance assessment of biogas production system requires the use of more than one system boundary. These can then be used in calculating output–input ratios of biogas production, biogas plant, biogas utilization and biogas production system, which can be used to analyze different parts of the biogas production chain. At the moment, it is difficult to compare different biogas plants since there is a wide variation of definitions for energy performance of biogas production. A more consistent way of analyzing energy performance would allow comparing biogas plants with each other and other recovery systems and finding possible locations for further improvement. Both from the GHG emission balance and energy performance point of view, the energy consumption at the biogas plant was the most significant factor. Renewable energy use to fulfil the parasitic energy demand at the plant would be the most efficient way to reduce the GHG emissions at the plant. The GHG emission reductions could be increased by upgrading biogas to biomethane and displacing natural gas or petrol use in cars when compared to biogas CHP production. The emission reductions from displacing mineral fertilizers with digestate were seen less significant, and the greater N2O emissions from spreading digestate might surpass the emission reductions from displacing mineral fertilizers.

Public management, policy capacity, innovation and development

In this paper we discuss the question of what factors in development policy create specific forms of policy capacity and under what circumstances developmentoriented complementarities or mismatches between the public and private sectors emerge. We argue that specific forms of policy capacity emerge from three interlinked policy choices, each fundamentally evolutionary in nature: policy choices on understanding the nature and sources of technical change and innovation; on the ways of financing economic growth, in particular technical change; and on the nature of public management to deliver and implement both previous sets of policy choices. Thus, policy capacity is not so much a continuum of abilities (from less to more), but rather a variety of modes of making policy that originate from co-evolutionary processes in capitalist development. To illustrate, we briefly reflect upon how the East Asian developmental states of the 1960s-1980s and Eastern European transition policies since the 1990s led to almost opposite institutional systems for financing, designing and managing development strategies, and how this led, through co-evolutionary processes, to different forms of policy capacity.
