Disclosure of tax information -from tax reporting system to the financial statements, Case: Fortum Oyj

The main target of the study was to examine how Fortum’s tax reporting system could be developed in a way that it collects required information which is also easily transferable to the financial statements. This included examining disclosure requirements for income taxes under IFRS and US GAAP. By benchmarking some Finnish, European and US companies the purpose was to get perspective in what extend they present their tax information in their financial statements. Also material weakness, its existence, was under examination. The research method was qualitative, descriptive and normative. The research material included articles and literature of the tax reporting and standards relating to it. The interviews made had a notable significance. The study pointed out that Fortum’s tax reporting is in good shape and it does not require big changes. The biggest renewal of the tax reporting system is that there is only one model for all Fortum’s companies. It is also more automated, quicker, and more efficient and it reminds more the notes in its shape. In addition it has more internal controls to improve quality and efficiency of the reporting process.

Quantitative Sustainability Disclosure –An international comparison and its impact on investor valuation

This research focuses on the link between quantitative sustainability disclosure and information asymmetry. It builds upon previous research which links information asymmetry with voluntary disclosure. Stakeholders from the financial services sector claim that sustainability disclosure needs to be more numerical and comparable between companies. This research covers 111 firms from Denmark, Finland, the Netherlands and Sweden from non-service industries and studies how quantitative their sustainability disclosure is, and whether or not there is a negative relation with information asymmetry. The results support the hypotheses, where two out of three information asymmetry proxies have a significant negative relation with quantitative disclosure. Size is supported as a moderating factor. Quantitativity also proves to have a significant link with third party sustainability ratings. The direct link between quantitativity and cost of capital is not however supported.

Open Environmental Information Upon Disclosure Request in China: The Paradox of Legal Mobilization

Taking a realist view that law is one form of politics, this dissertation studies the roles of citizens and organizations in mobilizing the law to request government agencies to disclose environmental information in China, and during this process, how the socio-legal field interacts with the political-legal sphere, and what changes have been brought about during their interactions. This work takes a socio-legal approach and applies methodologies of social science and legal analysis. It aims to understand the paradox of why and how citizens and entities have been invoking the law to access environmental information despite the fact that various obstacles exist and the effectiveness of the new mechanism of environmental information disclosure still remains low. The study is largely based on the 28 cases and eight surveys of environmental information disclosure requests collected by the author. The cases and surveys analysed in this dissertation all occurred between May 2008, when the OGI Regulations and the OEI Measures came into effect, and August 2012 when the case collection was completed. The findings of this study have shown that by invoking the rules of law made by the authorities to demand government agencies disclosing environmental information, the public, including citizens, organizations, law firms, and the media, have strategically created a repercussive pressure upon the authorities to act according to the law. While it is a top-down process that has established the mechanism of open government information in China, it is indeed the bottom-up activism of the public that makes it work. Citizens and organizations’ use of legal tactics to push government agencies to disclose environmental information have formed not only an end of accessing the information but more a means of making government agencies accountable to their legal obligations. Law has thus played a pivotal role in enabling citizen participation in the political process. Against the current situation in China that political campaigns, or politicization, from general election to collective actions, especially contentious actions, are still restrained or even repressed by the government, legal mobilization, or judicialization, that citizens and organizations use legal tactics to demand their rights and push government agencies to enforce the law, become de facto an alternative of political participation. During this process, legal actions have helped to strengthen the civil society, make government agencies act according to law, push back the political boundaries, and induce changes in the relationship between the state and the public. In the field of environmental information disclosure, citizens and organizations have formed a bottom-up social activism, though limited in scope, using the language of law, creating progressive social, legal and political changes. This study emphasizes that it is partial and incomplete to understand China’s transition only from the top-down policy-making and government administration; it is also important to observe it from the bottom-up perspective that in a realistic view law can be part of politics and legal mobilization, even when utterly apolitical, can help to achieve political aims as well. This study of legal mobilization in the field of environmental information disclosure also helps us to better understand the function of law: law is not only a tool for the authorities to regulate and control, but inevitably also a weapon for the public to demand government agencies to work towards their obligations stipulated by the laws issued by themselves.

Synchronous Digital Hierarchy implementation to a Radio Transmission Node

Kiristyville markkinoille on aina tuotava jotain uutta tarjottavaa ja SDH-kortti on yksi sellainen tuote jonka Nokia Networks julkistaa osaksi uutta Nokia Flexihub Nodea. Tavoitteena on suunnitella VC-12kanavoitu STM-1 kortti yhdistämään ylemmän tason tietoliikenneverkko suuren kapasiteetin radioon. Ennen kuin markkinoilla on valmis tuote, on sen takana valtaisa määrä työtä. Erilaisia dokumentteja on pitänyt tuottaa ja sopimuksia tehdä. Esimerkiksi vaatimusmäärittelyt on oltava selvät, jotta tiedetään mitä tuotteelta halutaan. Tätä ennen on kuitenkin pitänyt ymmärtää miten SDHtoimii ja miten otsikkotavuja käsitellään. Myös erilaiset piirivalinnat aiheuttavat miettimistä, sillä markkinoilla on runsaasti valmiita piirejä SDH signaalinkäsittelyyn. Varma tiedonsiirto on tärkeää puhelinoperaattorille ja siksi joudutaan miettimään varmennuksia ja niiden toteuttamista. Myös synkronointi on tärkeä osa SDH järjestelmää ja sen toteuttaminen hyvin on tärkeää. Hälytykset on otettava huomioon ja mietittävä, miten niiden käsittely saadaan hoidettua järkevästi, ilman että mikään järjestelmän osa ruuhkautuu kohtuuttomasti. Tässä Diplomityössä on tutustuttu SDH-järjestelmään, otsikkotavujen käsittelyyn ja vaatimusmäärittelyihin.

IFRS and Asymmetrical Information: Empirical Evidence from the Finnish Stock Markets

Tutkimuksen tavoitteena on selvittää kansainvälisiin tilinpäätösstandardeihin siirtymisen vaikutuksia epäsymmetriseen informaatioon Suomen osake-markkinoilla. Suomalaisten tilinpäätöskäytäntöjen ja kansainvälisten standardien eroja on selvitetty ensin laadullisin menetelmin,jonka jälkeen on tehty asymmetrisen informaation markkinapohjaisiin mittareihinperustuva kvantitatiivinen tutkimus. Yleisiin eroavaisuuksiin liittyvän selvityksen lisäksi on tutkittu erikseen erityisesti standardimuutoksen vaikutusta älylliseen pääomaan liittyvään informaation asymmetriaan. Empiirisessä osiossa älyllisen pääoman epäsuoraksi mitaksi on valittu kehitys- ja tutkimusmenojen suhde taseen loppusummaan. Kuten oletus oli, sekä laadullisen että empiirisen osion tulokset viittaavat siihen, että IFRS:n myötä informaatioympäristö on parantunut. Uudet standardit vaativat laajempaa ja tarkempaa informaation julkaisua liittyen älylliseen pääomaan, mikä ei ole kuitenkaan havaittavissa valituissa mittareissa

Ympäristöraportointimallinkehittäminen vesihuoltolaitokselle

Diplomityössä tarkastellaan ympäristöraportointia yrityksen ympäristöviestinnässä.Työn kirjallisuusosuudessa syvennytään ympäristöraporttien toteutukseen, tavoitteisiin, mahdollisuuksiin sekä raportointiohjeisiin ja -periaatteisiin. Työn kirjallisuusosassa käsitellään myös ympäristöjohtamista ja yrityksen sidosryhmiä. Diplomityön kirjallisuusosan ja yrityksen ohjauksen perusteella Joensuun Vedelle on kehitetty ympäristöraportointimalli, jota käyttäen yritys voi tehdä vuosittaista ympäristöraportointiaan. Ympäristöraportointimallin laadinta perustui erilaisiin raportointimalleihin, raportointiperiaatteisiin ja raportointiohjeisiin, kuten muiden muassa Global Reporting Initiativen (GRI) vapaaehtoiseen yhteiskuntavastuun raportointiohjeistoon ja Kirjanpitolautakunnan (KILA) yleisohjeeseen ympäristöasioiden kirjaamisesta, laskennasta ja esittämisestä tilinpäätöksessä. Joensuun Vedelle laaditunympäristöraportointimallin tavoitteena oli luoda laitokselle ympäristöraportti,joka sisältää merkittävimmät ympäristönäkökohdat, taloudellista vastuuta käsittelevän ympäristötilinpäätöksen sekä tietoa tärkeistä sosiaalisen vastuun asioista. Ympäristöraportin sisältämän tiedon kokoamisella haluttiin myös saada kokonaisvaltaista näkemystä, vuoden 2005 Joensuun, Kiihtelysvaaran ja Tuupovaaran kuntaliitoksen takia laajentuneen, Joensuun Veden toiminnan ympäristövaikutuksista. Diplomityössä on esitetty Joensuun Veden vuoden 2005 ympäristöraportin kokoamisenvaiheet sekä tulokset. Ympäristöraportointimalli täytti sille asetetut tavoitteet. Ympäristöraportin sisältöä tulee kuitenkin jatkossa kehittää sekä raportoitavan aineiston alkuperäisen dokumentoinnin osalta että sidosryhmien mielipiteidenja vaatimusten mukaisesti.

Läpinäkyvyys venäläisissä pörssiyhtiöissä - yhtiöiden Internetissä julkaisema informaatio

Tutkielman ensisijaisena tavoitteena oli selvittää, miten corporate governance eli hyvä hallintotapa on kehittynyt Venäjällä. Tutkimuksessa keskityttiin eritoten yritystoiminnan läpinäkyvyyteen ja siihen, minkälaista informaatiota yritysten pitäisi vuosittain julkaista. Tutkimuksessa tutkittiin minkälaista informaatiota Moskovan pörssiin listautuneet yritykset julkaisevat. Tavoitteena oli tutkia, julkaisevatko yritykset informaatiota OECD:n corporate governancve suositusten mukaisesti. Tutkimusmenetelmänä käytettiin havaintotutkimusta. Tutkimuksessa saatiin selkeä kuvasiitä, mitä corporate governance tarkoittaa ja siitä miten se on kehittynyt Venäjällä. Tutkimuksen aineisto kerättiin Moskovan pörssiin listautuneista yrityksistä, koska Venäjä tutkimuskohteena on mielenkiintoinen ja koska corporate governance teema on vasta viime vuosina tullut ajankohtaiseksi venäläisissä yrityksissä. Tutkimuksessa saadut tulokset osoittavat, että yritykset julkaisevat informaatiota melko hajanaisesti ja pörssi joutuu edelleen tyytymään puutteelliseen informaatioon. Venäjän yritystoiminnasta puuttuu vakaus, ja instituutiot eivät vielätue corporate governance -suositusten toimeenpanemista ainakaan kovin hyvin. Myös toimiala ja yrityksen omistusrakenne vaikuttavat jonkin verran siihen, minkälaista tietoa yritys tuottaa. Eri toimialojen välillä on huomattaviakin eroja sen suhteen, miten kattavasti niistä on saatavissa informaatiota. Omistusrakenne on tämän tutkimuksen yrityksissä erilainen kuin Venäjällä yleensä ja ulkomaista omistusta on paljon.

Patents in the Information and Communications Technology Sector - Development Trends, Problem Areas and Pressures for Change

The patent system was created for the purpose of promoting innovation by granting the inventors a legally defined right to exclude others in return for public disclosure. Today, patents are being applied and granted in greater numbers than ever, particularly in new areas such as biotechnology and information andcommunications technology (ICT), in which research and development (R&D) investments are also high. At the same time, the patent system has been heavily criticized. It has been claimed that it discourages rather than encourages the introduction of new products and processes, particularly in areas that develop quickly, lack one-product-one-patent correlation, and in which theemergence of patent thickets is characteristic. A further concern, which is particularly acute in the U.S., is the granting of so-called 'bad patents', i.e. patents that do not factually fulfil the patentability criteria. From the perspective of technology-intensive companies, patents could,irrespective of the above, be described as the most significant intellectual property right (IPR), having the potential of being used to protect products and processes from imitation, to limit competitors' freedom-to-operate, to provide such freedom to the company in question, and to exchange ideas with others. In fact, patents define the boundaries of ownership in relation to certain technologies. They may be sold or licensed on their ownor they may be components of all sorts of technology acquisition and licensing arrangements. Moreover, with the possibility of patenting business-method inventions in the U.S., patents are becoming increasingly important for companies basing their businesses on services. The value of patents is dependent on the value of the invention it claims, and how it is commercialized. Thus, most of them are worth very little, and most inventions are not worth patenting: it may be possible to protect them in other ways, and the costs of protection may exceed the benefits. Moreover, instead of making all inventions proprietary and seeking to appropriate as highreturns on investments as possible through patent enforcement, it is sometimes better to allow some of them to be disseminated freely in order to maximize market penetration. In fact, the ideology of openness is well established in the software sector, which has been the breeding ground for the open-source movement, for instance. Furthermore, industries, such as ICT, that benefit from network effects do not shun the idea of setting open standards or opening up their proprietary interfaces to allow everyone todesign products and services that are interoperable with theirs. The problem is that even though patents do not, strictly speaking, prevent access to protected technologies, they have the potential of doing so, and conflicts of interest are not rare. The primary aim of this dissertation is to increase understanding of the dynamics and controversies of the U.S. and European patent systems, with the focus on the ICT sector. The study consists of three parts. The first part introduces the research topic and the overall results of the dissertation. The second part comprises a publication in which academic, political, legal and business developments that concern software and business-method patents are investigated, and contentiousareas are identified. The third part examines the problems with patents and open standards both of which carry significant economic weight inthe ICT sector. Here, the focus is on so-called submarine patents, i.e. patentsthat remain unnoticed during the standardization process and then emerge after the standard has been set. The factors that contribute to the problems are documented and the practical and juridical options for alleviating them are assessed. In total, the dissertation provides a good overview of the challenges and pressures for change the patent system is facing,and of how these challenges are reflected in standard setting.

Railcarrier in Intermodal Freight Transportation Network

The major objective of this thesis is to describe and analyse how a railcarrier is engaged in an intermodal freight transportation network through its role and position. Because of the fact that the role as a conceptualisation has a lot of parallels with the position, both these phenomena are evaluated theoretically and empirically. VR Cargo (a strategical business unitof the Finnish railway company VR Ltd.) was chosen to be the focal firm surrounded by the actors of the focal net. Because of the fact that networks are sets of relationships rather than sets of actors, it is essential to describe the dimensions of the relationships created through the time thus having a past, presentand future. The roles are created during long common history shared by the actors especially when IM networks are considered. The presence of roles is embeddedin the tasks, and the future is anchored to the expectations. Furthermore, in this study role refers to network dynamics, and to incremental and radical changes in the network, in a similar way as position refers to stability and to the influences of bonded structures. The main purpose of the first part of the study was to examine how the two distinctive views that have a dominant position in modern logistics ¿ the network view (particularly IMP-based network approach) and the managerial view (represented by Supply Chain Management) differ, especially when intermodalism is under consideration. In this study intermodalism was defined as a form of interorganisational behaviour characterized by the physical movement of unitized goods with Intermodal Transport Units, using more than one mode as performed by the net of operators. In this particular stage the study relies mainly on theoretical evaluation broadened by some discussions with the practitioners. This is essential, because the continuous dialogue between theory and practice is highly emphasized. Some managerial implications are discussed on the basis of the theoretical examination. A tentative model for empirical analysis in subsequent research is suggested. The empirical investigation, which relies on the interviews among the members in the focal net, shows that the major role of the focal company in the network is the common carrier. This role has some behavioural and functional characteristics, such as an executive's disclosure expressing strategic will attached with stable and predictable managerial and organisational behaviour. Most important is the notion that the focal company is neutral for all the other operators, and willing to enhance and strengthen the collaboration with all the members in the IM network. This also means that all the accounts are aimed at being equal in terms of customer satisfaction. Besides, the adjustments intensify the adopted role. However, the focal company is also obliged tosustain its role as it still has a government-erected right to maintain solely the railway operations on domestic tracks. In addition, the roles of a dominator, principal, partner, subcontractor, and integrator were present appearing either in a dyadic relationship or in net(work) context. In order to reveal differentroles, a dualistic interpretation of the concept of role/position was employed.

Lossless compression of hyperspectral images

Technological progress has made a huge amount of data available at increasing spatial and spectral resolutions. Therefore, the compression of hyperspectral data is an area of active research. In somefields, the original quality of a hyperspectral image cannot be compromised andin these cases, lossless compression is mandatory. The main goal of this thesisis to provide improved methods for the lossless compression of hyperspectral images. Both prediction- and transform-based methods are studied. Two kinds of prediction based methods are being studied. In the first method the spectra of a hyperspectral image are first clustered and and an optimized linear predictor is calculated for each cluster. In the second prediction method linear prediction coefficients are not fixed but are recalculated for each pixel. A parallel implementation of the above-mentioned linear prediction method is also presented. Also,two transform-based methods are being presented. Vector Quantization (VQ) was used together with a new coding of the residual image. In addition we have developed a new back end for a compression method utilizing Principal Component Analysis (PCA) and Integer Wavelet Transform (IWT). The performance of the compressionmethods are compared to that of other compression methods. The results show that the proposed linear prediction methods outperform the previous methods. In addition, a novel fast exact nearest-neighbor search method is developed. The search method is used to speed up the Linde-Buzo-Gray (LBG) clustering method.

ADSL-linjan fyysisen kerroksen testauksen automatisointi

ADSL (Asymmetrical Digital Subsciber Line) on puhelinkaapelia siirtotienä käyttävä nopea Internet-liityntäteknologia, joka on yleistynyt viime vuosina kuluttajamarkkinoilla. Analoginen puhelinverkko on alun perin tarkoitettu puheen siirtoon 0-4kHz:n äänitaajuuskanavalla, mikä aiheuttaa rajoitteita datasiirtoon ylemmillä taajuuksilla. Puhelinverkkojen rakenne vaihtelee alueittain sisältäen erilaisia datasiirtoa häiritseviä tekijöitä. Tämän vuoksi ADSL-päätelaitteilta vaaditaan sopeutumiskykyä vaativiinkin olosuhteisiin. Nykyiset ADSL-standardit eivät vaadi päätelaitteilta riittävää suorituskykyä, jotta luotettava tiedonsiirto onnistuisi myös huonoissa verkko-olosuhteissa. Epäkohdan korjaamiseksi DSL Forum on kehittänyt yhdessä laitevalmistajien, tietoliikenneoperaattoreiden ja komponenttivalmistajien kanssa ADSL-päätelaitteiden yhteensopivuustestaukseen testipaketin nimeltä TR-048. Se on kattava joukko tarkkaan kuvattuja testejä, joissa keskitytään enimmäkseen fyysisen kerroksen testaamiseen. TR-048:aa ei vaadita vielä nykyisissä ADSL-standardeissa, mutta yksityiset laboratoriot ja laitetoimittajat ovat vähitellen ottamassa sitä käyttöön. Tämän työn keskeisenä tavoittena oli tehdä sovellus, jolla automatisoitiin suurin osa TR-048:n sisältämien ADSL-linjan fyysisen kerroksen testeistä. Valmiilla sovelluksella ajetun testikierroksen perusteella arvioitiin sovelluksesta saatua hyötyä ja tuotekehitysvaiheessa olevan Nokia D500 tilaajasolmun suorituskykyä. Työn teoriaosassa esitellään ADSL-teknologiaa ja ADSL-lähetin-vastaanottimen loogista toimintaa.
