Metsäsääntely Suomessa ja Venäjällä. Näkökulmia kestävään metsätalouteen

Sustainability is the aim of forest management and forest regulation in many countries. Accordingly, forest management has been steered towards more environmentally friendly methods and new regulatory instruments have been introduced. At the same time, wood trade and forest industry have become a global business. Even if the importance of national forest legislation has not decreased, it has been widely acknowledged that national regulation of forest management is no longer sufficient. The movement of goods does not acknowledge boundaries, even though most negative environmental and social consequences stay in the country of origin of wood and other raw materials. As a partial solution to this dilemma, different kinds of regulations have been developed. Various forest certification schemes and wood trade regulation in the EU (995/2010) are examples of efforts to prevent illegal logging and unsustainable forestry. The Finland-based forest industry is to a varying extent dependent on wood trade from Russia. Especially in the 1990‟s, ethical questions concerning import of wood from Russian old growth forests near the Finnish border were widely discussed. Consequently, forest industry enterprises have developed systems to trace the origin of wood and to buy certified wood from Russia. The aim of the research has been to evaluate Finnish and Russian forest regulations in order to investigate what kind of forest management these regulations enhance, and to what extent ecologically sustainable forest management has been integrated into different forms of regulation. I have examined Finnish and Russian forest regulation in four separate articles based on the topics of the Russian Forest Code, forest certification and other voluntary forest protection measures in Russia, Finnish forest certification and Finnish forest legislation. One objective has been to analyse the roles voluntary forest certification plays in promoting sustainable forest management in different countries. In my research, I have mainly concentrated on ecological sustainability and protection of biodiversity, although other aspects of sustainable forest management have been touched upon in different articles. In the following I shall conclude the findings of my research. When the current Russian Forest Code (2006) was being adopted, the main emphasis was not on ecological issues, but on reorganizing forest governance. The role of ecological requirements was even slightly diminished during the legislative reform. There are, nevertheless, still stipulations aiming at ecological sustainability, such as the division of forests into different forest management categories and various protection zones. In 2000, FSC forest certification arrived in Russia, at present covering already 28 million hectares of forests. The PEFC scheme is now in use as well, but to a much lesser extent. If properly implemented, Russian forest certification schemes clearly improve the level of ecological and social sustainability of forestry in Russia. Certification criteria, however, are partly in conflict with the Russian forest legislation and certified enterprises have been forced to pay fines or to negotiate with forest authorities. This clearly indicates that even if Russian forest legislation has otherwise been liberalized to a certain extent, some significant paternalism still exists. Voluntary, hands-on biodiversity protection measures are not valued, and they are not part of the official protection policies as in many other countries. However, there have been some regional solutions to this dilemma. In the Republic of Karelia forest authorities have approved a set of forest biodiversity protection rules created by a local NGO and a forest industry enterprise. By following these local rules, an enterprise can avoid fines for protection measures. The current Finnish Forest Act was adopted in 1996. It brought forest legislation into a new era as some ecological aspects were integrated into forest legislation. The various soft-law forest management recommendations further increased the level of biodiversity protection. My evaluation of the overall legitimacy of the Finnish forest legislation and forest management paradigm revealed, however, several problematic issues. As part of this study I analysed the history of the current forest management paradigm. This analysis revealed the path dependency which still hinders the protection of biodiversity and clearly decreases the general legitimacy of forest management. Due to several historical reasons only even-structured forest management based on clear cuts has for decades been officially approved in Finland. Due to increasing demands of forest owners the legislation is finally being revised. Yet, the official approval of uneven-structured forest management would not be enough to fully improve ecological, social and cultural legitimacy. The latest ecological theories and knowledge of endangered species should be taken into account in the on-going reform of forest legislation as well as the modernisation. Forest legislation is one of the very few spheres of Finnish environmental legislation where openness and participation are still considered a threat. The first Finnish forest certification scheme, PEFC, was established in 2000. It now covers more than 20 million hectares, about 95% of the forests in Finland. PEFC Finland does not require a higher level of biodiversity protection than the recommendations by Tapio (the Development Centre for Forestry), but certification has unified forest management practices and requires more protection measures than mere forest legislation. The study suggests that in Finland PEFC has not functioned as an instrument which would substantially improve the level of forest management. Rather it has supported the status quo of the forest sector. While the ecological and social responsibility of Finland-based forest corporations was one impetus for this research, I want to conclude that there are problems related to forest legislation and non-state regulation in both Finland and Russia. If an enterprise buying wood from Russia buys only certified wood, and carefully avoids wood coming from high conservation value forests that are either ecologically or socially valuable, it can be claimed to be as sustainably produced as in Finland. However, there must be continuous scrutiny of the circumstances. In Russia, the level of the compliance of certification criteria varies considerably, and there are vast unprotected invaluable forest areas. The utilisation of these areas should not be based on short-sighted decisions or lack of consensus among stakeholders.

Developing markets of energy biomass – local and global perspectives

The thesis explores global and national-level issues related to the development of markets for biomass for energy. The thesis consists of five separate papers and provides insights on selected issues. The aim of Paper I was to identify methodological and statistical challenges in assessing international solid and liquid biofuels trade and provide an overview of the Finnish situation with respect to the status of international solid and liquid biofuels trade. We found that, for the Finnish case, it is possible to qualify direct and indirect trade volumes of biofuels. The study showed that indirect trade of biofuels has a highly significant role in Finland and may be a significant sector also in global biofuels trade. The purpose of Paper II was to provide a quantified insight into Finnish prospects for meeting the national 2020 renewable energy targets and concurrently becoming a largescale producer of forest-biomass-based second-generation biofuels for feeding increasing demand in European markets. We found that Finland has good opportunities to realise a scenario to meet 2020 renewable energy targets and for large-scale production of wood-based biofuels. The potential net export of transport biofuels from Finland in 2020 would correspond to 2–3% of European demand. Paper III summarises the global status of international solid and liquid biofuels trade as illuminated by several separate sources. International trade of biofuels was estimated at nearly 1 EJ for 2006. Indirect trade of biofuels through trading of industrial roundwood and material by-products comprises the largest proportion of the trading, with a share of about two thirds. The purpose of Paper IV was to outline a comprehensive picture of the coverage of various certification schemes and sustainability principles relating to the entire value-added chain of biomass and bioenergy. Regardless of the intensive work that has been done in the field of sustainability schemes and principles concerning use of biomass for energy, weaknesses still exist. The objective of Paper V was to clarify the alternative scenarios for the international biomass market until 2020 and identify the underlying steps needed toward a wellfunctioning and sustainable market for biomass for energy purposes. An overall conclusion drawn from this analysis concerns the enormous opportunities related to the utilisation of biomass for energy in the coming decades.

Painelaitteiden kunnonvalvonta ja kemikaaliputkistojen rakennuttaminen

Painelaitteet ja kemikaaliputkistot ovat yleisiä varsinkin kemian alan yrityksissä. Omista-jan ja haltijan on tiedettävä niihin liittyvä lainsäädäntö, ja osattava soveltaa niitä käytän-töön. Työssä on selvitetty painelaitteisiin ja kemikaaliputkistoihin liittyvän lainsäädännön olen-naisin sisältö. Nykyisin painelaitteiden määräaikaistarkastuksia voidaan korvata painelait-teen seurannalla ja kunnonvalvontajärjestelmällä. Mitä se käytännössä tarkoittaa, ja onko Suomessa mahdollisuutta kuinka laajasti hyödynnetty? On tärkeää tuntea painelaitteiden ja kemikaaliputkistojen vikaantumismekanismit ja kunnonvalvontamenetelmät, jotta yritys voi luoda omaan toimintaympäristöön soveltuvan kunnonvalvontajärjestelmän tai paine-laitteiden seurannan. On pyrittävä siihen, että ongelmat havaitaan, ennen kuin vaurio syn-tyy. Kunnonvalvontajärjestelmän luomiseen ja ylläpitoon voidaan hyödyntää painelaittei-den riskiperusteiseen kunnossapitoon ja tarkastukseen tarkoitettua menettelyä. Työssä on tarkemmin käyty läpi menettelyn sisältö. Kustannustehokkuus ja tuotantolaitteiden käytettävyys ovat nousseet tärkeiksi osa-alueiksi kilpailukyvyn takaamiseksi. Painelaitteiden tarkastuksista ja muista painelaitteisiin ja ke-mikaaliputkistoihin liittyvistä ennakkohuolloista syntyvät kustannukset ovat merkittäviä. Näihin kohdistuvia kustannussäästöjä voidaan saavuttaa monin keinoin huonontamatta kuitenkaan turvallisuutta. Työssä on selvitetty kohdeyrityksen painelaitteet ja kemikaali-putkistot. Lisäksi on käyty läpi nykyinen tarkastusjaksotus, keskeisimmät viat ja tarkastuk-siin liittyvää kustannushistoriaa. Lopputuloksena on syntynyt esiselvitys ja kemikaaliputkistojen hankkimista helpottavaa tietoa. Esiselvityksen avulla kohdeyritys voi yhdessä kunnossapitoyrityksen kanssa laatia strategian painelaitteiden kunnossapidolle ja tarkastuksille. Merkittäviä kustannussäästöjä on saavutettavissa ehdotetuilla jatkotoimenpiteillä, vaikka päädyttäisiin edelleen painelait-teiden tarkastuksien osalta noudattamaan olemassa olevaa käytäntöä.

Strategisten muutosohjelmien tehostaminen IT-yrityksessä tietojohtamisen keinoilla

Tutkimusten mukaan suurin osa strategisista muutoshankkeista epäonnistuu. Tässä diplomityössä selvitettiin syitä epäonnistumisiin sekä kartoitettiin mahdollisuuksia tehostaa muutosjohtamista tietojohtamisen keinoilla. Lisäksi työssä laadittiin muutosjohtamisen kehittämissuositukset yhdelle tutkimuksen kohteena olleelle IT-yritykselle. Tietojohtamisen kannalta muutosjohtamista tarkasteltiin erityisesti seuraavista neljästä näkökulmasta: 1) muutostarpeiden havainnointi, 2) muutoksiin suhtautuminen, 3) luottamus ja hiljainen tieto sekä 4) muutosviestintä. Empiriaosuudessa koottiin muutosjohtamisen kokemuksia kolmesta Suomessa toimivasta IT-yrityksestä. Lisänäkemystä aiheeseen haettiin kolmelta kokeneelta muutosjohtamisen asiantuntijalta. Muutosten onnistumista vaarantavat lukuisat eri tekijät. Liiketoiminnan kauan jatkunut menestys saattaa rajoittaa muutostarpeiden havaitsemista ajoissa. Luutuneet käsitykset, luottamuksen puute ja päättäjien liian vallitsevat henkilökohtaiset näkemykset estävät uusien ideoiden esiin nousemista. Muutosjohtaminen vaatii päivittäisestä johtamisesta poikkeavia erityisosaamisia. Lisäksi henkilöstön muutosvastarinta ja muutosprosessin haasteellisuus nostavat epäonnistumisen todennäköisyyttä. Tämän tutkimuksen mukaan tietojohtamisen keinoilla on mahdollisuus tehostaa muutosjohtamista. Organisaation hiljaisen tiedon saattaminen yhteiseen käyttöön edistää sekä muutostarpeiden tunnistamista että muutoshankkeiden läpivientiä. Muutosjohtamiskoulutuksella ja tiedon tehokkaalla jakamisella parannetaan henkilöstön muutosvalmiuksia ja pienennetään muutosvastarintaa. Yhtenäisellä muutosprosessilla tehostetaan muutosten läpivientiä. Muutosmyönteisen organisaatiokulttuurin luomisella on keskeinen rooli muutosvalmiuksien kehittämisessä. Muutosvision luomisella sekä laadukkaalla ja muutosviestinnällä luodaan turvallisuuden tunnetta ja varmistetaan huomion pysyminen muutoksen tavoitteiden kannalta oikeissa asioissa.

"Dov'è la sinistra?" Hemispatial neglect in stroke

As long as the incidence of stroke continues to grow, patients with large right hemisphere lesions suffering from hemispatial neglect will require neuropsychological evaluation and rehabilitation. The inability to process information especially that coming from the left side accompanied by the magnetic orientation to the ipsilesional side represents a real challenge for rehabilitation. This dissertation is concerned with crucial aspects in the clinical neuropsychological practice of hemispatial neglect. In studying the convergence of the visual and behavioural test batteries in the assessment of neglect, nine of the seventeen patients, who completed both the conventional subtests of the Behavioural Inattention Test and the Catherine Bergego Scale assessments, showed a similar severity of neglect and thus good convergence in both tests. However, patients with neglect and hemianopia had poorer scores in the line bisection test and they displayed stronger neglect in behaviour than patients with pure neglect. The second study examined, whether arm activation, modified from the Constraint Induced Movement Therapy, could be applied as neglect rehabilitation alone without any visual training. Twelve acute- or subacute patients were randomized into two rehabilitation groups: arm activation training or traditional voluntary visual scanning training. Neglect was ameliorated significantly or almost significantly in both training groups due to rehabilitation with the effect being maintained for at least six months. In studying the reflections of hemispatial neglect on visual memory, the associations of severity of neglect and visual memory performances were explored. The performances of acute and subacute patients with hemispatial neglect were compared with the performances of matched healthy control subjects. As hypothesized, encoding from the left side and immediate recall of visual material were significantly compromised in patients with neglect. Another mechanism of neglect affecting visual memory processes is observed in delayed visual reproduction. Delayed recall demands that the individual must make a match helped by a cue or it requires a search for relevant material from long-term memory storage. In the case of representational neglect, the search may succeed but the left side of the recollected memory still fails to open. Visual and auditory evoked potentials were measured in 21 patients with hemispatial neglect. Stimuli coming from the left or right were processed differently in both sensory modalities in acute and subacute patients as compared with the chronic patients. The differences equalized during the course of recovery. Recovery from hemispatial neglect was strongly associated with early rehabilitation and with the severity of neglect. Extinction was common in patients with neglect and it did not ameliorate with the recovery of neglect. The presence of pusher symptom hampered amelioration of visual neglect in acute and subacute stroke patients, whereas depression did not have any significant effect in the early phases after the stroke. However, depression had an unfavourable effect on recovery in the chronic phase. In conclusion, the combination of neglect and hemianopia may explain part of the residual behavioural neglect that is no longer evident in visual testing. Further research is needed in order to determine which specific rehabilitation procedures would be most beneficial in patients suffering the combination of neglect and hemianopia. Arm activation should be included in the rehabilitation programs of neglect; this is a useful technique for patients who need bedside treatment in the acute phase. With respect to the deficit in visual memory in association with neglect, the possible mechanisms of lateralized deficit in delayed recall need to be further examined and clarified. Intensive treatment induced recovery in both severe and moderate visual neglect long after the first two to first three months after the stroke.

Leda förändring genom relationer, processer och kultur

Forskningens syfte var att bidra med en ny kunskapssyntes om vad det innebär att leda förändring ur ett vårdvetenskapligt perspektiv. Vårdledaren har, speciellt vid större förändringar inom organisationen, en stor betydelse för hur vårdandet förvaltas genom att hålla den vårdande traditionen levande och genom formningen av den vårdande kulturen och vårdgemenskapen. Den övergripande hermeneutiska forskningsansatsen med tillämpning av metodologisk triangulering har influerats av Gadamers, Ricoeurs och Ödmans syn på hermeneutik med förståelse och förklaring som kompletterar varandra. Forskningens övergripande frågeställning ”Vad innebär det att leda förändring ur ett vårdvetenskapligt perspektiv?” förankrades i de fyra underliggande frågeställningarna. Den första frågeställningen berörde meningsinnehållet i begreppet förändring samt dess gestaltning. Metoden var en hermeneutisk begreppsbestämning på en ontologisk och kontextuell nivå enligt Koorts metod för begreppsbestämning. Genom en personalenkät undersöktes personalens åsikter (totalt 597 personer) om den kommande fusionen och förändringen samt deras förväntningar på ledarna under förändringsprocessen för att få svar på vad förutsättningarna var för en förändring eller förändringsprocess med avsedda mål och effekter. Svaret på hur vårdledaren och dennes uppgifter gestaltades vid en förändring samt hur vårdledarna uppfattade förändring och den kommande förändringsprocessen erhölls genom djupintervjuer med vårdledare (17). Av resultatet framgår att vårdledaren leder förändring genom att leda relationer, processer och kultur och genom ett stödjande, reflekterande och kulturbärande ledarskap med syftet att åstadkomma en verklig och hållbar förändring. För att åstadkomma en verklig och hållbar förändring, dvs. en inre omgestaltning och omdaning som vardande, förutsätts dock att både tankemönster och handlanden förändras. Riktningen och insatserna för förändringen skall ha sin grund i en tydlig och meningsfull målsättning och vision utgående från en gemensam värdegrund. En arena för dialog borde utvecklas så att förändringens liksom även vårdandets vision och mission förankras och utvecklas till handling och förändring. Vårdledarens primära uppgift eller mission var att tillhandahålla varje individuell patient en god vård. Den primära missionen var med andra ord att med ansvarsfullhet tjäna vårdandet sak utgående från ett etiskt förhållningssätt. I tjänande av vårdandets sak fanns dock en tillit till att förändringen gagnar patienten och hans eller hennes vård, men vårdledarnas anpassning till förändringen var utan djupare engagemang. Vårdledarna kände även en oro för sitt uppdrag som vårdledare, vårdarbetets ställning och mandatet som patientens advokat. Vårdledaren är också en kulturbärare, vilket innebär att även kulturen har betydelse under en förändringsprocess. Genom att leda kulturen skapar vårdledaren en öppen, bekräftande och evidensbaserad atmosfär med centrala värderingar som ger uttryck för den rådande andan och kulturen.

Monte Carlo Hypothesis Testing with The Sharpe Ratio

The purpose of this master thesis was to perform simulations that involve use of random number while testing hypotheses especially on two samples populations being compared weather by their means, variances or Sharpe ratios. Specifically, we simulated some well known distributions by Matlab and check out the accuracy of an hypothesis testing. Furthermore, we went deeper and check what could happen once the bootstrapping method as described by Effrons is applied on the simulated data. In addition to that, one well known RobustSharpe hypothesis testing stated in the paper of Ledoit and Wolf was applied to measure the statistical significance performance between two investment founds basing on testing weather there is a statistically significant difference between their Sharpe Ratios or not. We collected many literatures about our topic and perform by Matlab many simulated random numbers as possible to put out our purpose; As results we come out with a good understanding that testing are not always accurate; for instance while testing weather two normal distributed random vectors come from the same normal distribution. The Jacque-Berra test for normality showed that for the normal random vector r1 and r2, only 94,7% and 95,7% respectively are coming from normal distribution in contrast 5,3% and 4,3% failed to shown the truth already known; but when we introduce the bootstrapping methods by Effrons while estimating pvalues where the hypothesis decision is based, the accuracy of the test was 100% successful. From the above results the reports showed that bootstrapping methods while testing or estimating some statistics should always considered because at most cases the outcome are accurate and errors are minimized in the computation. Also the RobustSharpe test which is known to use one of the bootstrapping methods, studentised one, were applied first on different simulated data including distribution of many kind and different shape secondly, on real data, Hedge and Mutual funds. The test performed quite well to agree with the existence of statistical significance difference between their Sharpe ratios as described in the paper of Ledoit andWolf.

Suomen metsäteollisuuden päästökehitys vuoteen 2020

Metsäteollisuudessa on käynnissä rakennemuutos, joka tuo haasteita toimialan ympäristöasioiden hallintaan sekä ympäristölupia myöntävän ja valvovan viranomaisen toimintaan. Lähivuosina tulee myös runsaasti voimaan uutta lainsäädäntöä, joka vaikuttaa metsäteollisuuden ympäristöasioiden hallintaan. Tämän työn tarkoituksena oli arvioida Suomen kemiallisen metsäteollisuuden päästökehitystä vuoteen 2020 huomioiden metsäteollisuuden uusi tuotanto sekä lähivuosina voimaan tuleva ympäristölainsäädäntö, erityisesti päivitettävänä oleva massa- ja paperiteollisuuden BREF-asiakirja. Päästökehitystä arvioitiin viiden skenaarion avulla. Vesistöpäästöjen osalta tarkasteltiin COD- ja AOX-päästöjä sekä typpi- ja fosforipäästöjä, ja ilmapäästöjen osalta sellun tuotannon rikki- ja typpioksidi- sekä hiukkaspäästöjä. Massan- ja paperintuotannon oletettiin pysyvän muutaman prosentin nykyistä tasoa korkeammalla tasolla. Uuden tuotannon osalta kahdessa skenaariossa huomioitiin nestemäisten biopolttoaineiden tuotanto kolmella laitoksella, yhteensä 600 000 t/a. Päästölaskennassa käytettiin päivitettävänä olevan massa- ja paperiteollisuuden BREF-asiakirjan BAT-päätelmissä annettuja luonnoksia uusista päästötasoista. Skenaarioiden pohjalta havaittiin, että massa- ja paperiteollisuuden BAT-päätelmien mukaiset päästötasot eivät tuo merkittäviä muutoksia metsäteollisuuden vesistöpäästöihin vuoteen 2020 mennessä. Biojalosteiden tuotannon vaikutus vesistöpäästöihin todettiin myös hyvin vähäiseksi. Sen sijaan ilmaan johdettavat päästöt pienenevät huomattavasti: hiukkaspäästöt vähenivät 42–50 prosenttia uusien päästötasojen myötä. Biojalosteiden tuotannon vaikutus oli myös merkittävämpi kuin ilmapäästöihin kuin vesistöpäästöihin. Prosentuaalisesti eniten biojalostus lisäsi rikkidioksidipäästöjä.

Professional sports and gambling regulation in Finland - Examining the institutional factors of gambling affecting professional sport clubs in Finland

This study examines how to institutional environment of gambling is currently in motion both in Europe and Finland. Furthermore, it examines the criticism by Finnish professional sport clubs directed towards the national gambling monopolies, especially Veikkaus Oy. This criticism addresses the acclaimed issue of low or non-existing sponsorship funds coming to the clubs despite the clubs’ duties to promote Veikkaus Oy in their stadiums etc. In essence the main research objective was to examine the interaction and institutional environments of both Finnish professional sport clubs and gambling regulation. This was done through three sub-objectives: 1) to analyze professional sport as business and its institutional environment 2) to analyze the institutions of gambling in their current state and their potential future 3) to evaluate the potential impact of an institutional change in gambling legislation to the professional sport clubs The findings from Finland were then compared to those of Denmark where an institutional change had occurred in gambling regulation. Empirical data was collected through multiple interviews. Interviewees represented sport clubs (7), sport association (1), sport league (1), Finnish monopoly representatives (2), commercial gambling providers (1), Danish monopoly system representatives (1), Danish sport club (1). In addition a vast amount of secondary data (e.g. Green and white books by EU, court decisions, a variety of studies etc.). Theoretically this study combines the aspects of institutional theory with the theory of professional sports as business. This proved to be a rather new approach and no published literature was found to have done specifically this. The findings of this study are twofold, on the European level it is clear that the momentum if towards a more liberated gambling market while Finland is at the moment trying to go the opposite direction and uphold its monopoly. From the sport club’s level the findings suggest that currently sport clubs do not directly benefit from the funds originated from Veikkaus Oy as these funds are more or less used on the association/league levels. However, the clubs themselves are also lacking in self-criticism as they are lacking in clear sponsorship packages/programs which Veikkaus Oy might be interested in participating. If liberation of the gambling market would occur it is highly possible that that the largest clubs in football and ice-hockey would be the main beneficiaries while smaller clubs and sports could possibly be worse off than currently. These interpretations were well supported by the findings from Denmark.

Lean, Six Sigma ja Total Welding Management hitsaavassa verkostossa

Diplomityössä tarkastellaan hitsaavan verkoston laadunhallintaa ja siinä ilmeneviä erilaisia ongelmakohtia. Tämän lisäksi työssä tarkastellaan kolmen eri laatutyökalun Lean, Six Sigma ja Total Welding Management soveltamista hitsaavan verkoston laadunhallinnassa. Teoriaosassa käsitellään sekä yleisesti että hitsauksen osalta laatua ja laadunhallintaa, sekä edellä mainittuja laatutyökaluja. Tutkimusosaan tietoja hitsaavista verkostoista kerättiin kaikkiaan kolmesta eri verkostosta. Näiden kerättyjen tietojen pohjalta tarkasteltiin valittujen laatutyökalujen soveltuvuutta verkostomaiseen käyttöön. Verkostoitunut toiminta aiheuttaa monia uusia haasteita yritysten laadunhallinnalle verrattuna yksittäisiin hitsaaviin yrityksiin. Suurimpia tutkimuksessa havaittuja ongelmakohtia ovat suunnittelun ja valmistuksen yhteistyön erilaiset puutteet, laatutasoon ja sen varmistukseen liittyvät asiat, sekä verkoston sisälle syntyvä niin sanottu hiljainen tieto ja sen häviäminen. Tutkimuksen tarkastelujen perusteella havaittiin, että kaikkien tutkimukseen valitun kolmen laatutyökalun soveltaminen myös verkostomaisessa toiminnassa on mahdollista, mutta se vaatii huomattavasti suurempaa työpanosta kuin soveltaminen yksittäisessä yrityksessä. Myös näiden kaikkien kolmen työkalun yhtä aikainen käyttö on mahdollista. Juuri oikean työkalun valitseminen kullekin hitsaavalle verkostolle vaatii tarkkaa perehtymistä verkostoon ja sen tilanteeseen.

Deregulation’s Impact on the Railway Freight Transport Sector’s Future in the Baltic Sea Region

The European transport market has confronted several changes during the last decade. Due to European Union legislative mandates, the railway freight market was deregulated in 2007. The market followed the trend started by other transport modes as well as other previously regulated industries such as banking, telecommunications and energy. Globally, the first country to deregulate the railway freight market was the United States, with the introduction of the Staggers Rail Act in 1980. Some European countries decided to follow suit already before regulation was mandated; among the forerunners were the United Kingdom, Sweden and Germany. The previous research has concentrated only on these countries, which has provided an interesting research gap for this thesis. The Baltic Sea Region consists of countries with different kinds of liberalization paths, including Sweden and Germany, which have been on the frontline, whereas Lithuania and Finland have only one active railway undertaking, the incumbent. The transport market of the European Union is facing further challenges in the near future, due to the Sulphur Directive, oil dependency and the changing structure of European rail networks. In order to improve the accessibility of this peripheral area, further action is required. This research focuses on topics such as the progression of deregulation, barriers to entry, country-specific features, cooperation and internationalization. Based on the research results, it can be stated that the Baltic Sea Region’s railway freight market is expected to change in the future. Further private railway undertakings are anticipated, and these would change the market structure. The realization of European Union’s plans to increase the improved rail network to cover the Baltic States is strongly hoped for, and railway freight market counterparts inside and among countries are starting to enhance their level of cooperation. The Baltic Sea Region countries have several special national characteristics which influence the market and should be taken into account when companies evaluate possible market entry actions. According to thesis interviews, the Swedish market has a strong level of cooperation in the form of an old-boy network, and is supported by a positive attitude of the incumbent towards the private railway undertakings. This has facilitated the entry process of newcomers, and currently the market has numerous operating railway undertakings. A contrary example was found from Poland, where the incumbent sent old rolling stock to the scrap yard rather than sell it to private railway undertakings. The importance of personal relations is highlighted in Russia, followed by the railway market’s strong political bond with politics. Nonetheless, some barriers to entry are shared by the Baltic Sea Region, the main ones being acquisition of rolling stock, bureaucracy and needed investments. The railway freight market is internationalizing, which is perceived via several alliances as well as the increased number of mergers and acquisitions. After deregulation, markets seem to increase the number of railway undertakings at a rather fast pace, but with the passage of time, the larger operators tend to acquire smaller ones. Therefore, it is expected that in a decade’s time, the number of railway undertakings will start to decrease in the deregulation pioneer countries, while the ones coming from behind might still experience an increase. The Russian market is expected to be totally liberalized, and further alliances between the Russian Railways and European railway undertakings are expected to occur. The Baltic Sea Region’s railway freight market is anticipated to improve, and, based on the interviewees’ comments, attract more cargoes from road to rail.

Excelling in procurement : IT Contract Management with Lean and Six Sigma. Case study on legacy contract management at Philips Global IT.

Few people see both opportunities and threats coming from IT legacy in current world. On one hand, effective legacy management can bring substantial hard savings and smooth transition to the desired future state. On the other hand, its mismanagement contributes to serious operational business risks, as old systems are not as reliable as it is required by the business users. This thesis offers one perspective of dealing with IT legacy – through effective contract management, as a component towards achieving Procurement Excellence in IT, thus bridging IT delivery departments, IT procurement, business units, and suppliers. It developed a model for assessing the impact of improvements on contract management process and set of tools and advices with regards to analysis and improvement actions. The thesis conducted case study to present and justify the implementation of Lean Six Sigma in IT legacy contract management environment. Lean Six Sigma proved to be successful and this thesis presents and discusses all the steps necessary, and pitfalls to avoid, to achieve breakthrough improvement in IT contract management process performance. For the IT legacy contract management process two improvements require special attention and can be easily copied to any organization. First is the issue of diluted contract ownership that stops all the improvements, as people do not know who is responsible for performing those actions. Second is the contract management performance evaluation tool, which can be used for monitoring, identifying outlying contracts and opportunities for improvements in the process. The study resulted in a valuable insight on the benefits of applying Lean Six Sigma to improve IT legacy contract management, as well as on how Lean Six Sigma can be applied in IT environment. Managerial implications are discussed. It is concluded that the use of data-driven Lean Six Sigma methodology for improving the existing IT contract management processes is a significant addition to the existing best practices in contract management.

Verkostoinvestointien optimointi uuden sähkömarkkinalain ympäristössä

Vuonna 2013 uudistunut sähkömarkkinalaki toi sähköverkkoyhtiöille velvoitteen parantaa sähkönjakeluverkkojensa toimintavarmuutta suurhäiriötilanteissa. Toimenpiteet tämän velvoitteen täyttämiseksi näkyvät merkittävinä verkostoinvestointeina. Diplomityössä tarkastellaan uudistuneen sähkömarkkinalain tuomia vaikutuksia Imatran Seudun Sähkön jakeluverkkoa koskeviin verkostoinvestointeihin. Päätavoitteena on selvittää, millaisia toimenpiteitä uuden sähköntoimitusvarmuustason vaatimusten täyttämiseksi tarvitaan ja mitkä ovat optimaaliset ratkaisut näiden toimenpiteiden toteuttamiseksi. Uudella sähköntoimitusvarmuustasolla on vaikutusta jakeluverkon rakennemuutoksiin tulevien 15 vuoden aikana, mutta näiden rakennemuutosten vaikutukset kantavat useiden kymmenien vuosien päähän.
