Konsernitilinpäätöksen yhdistelyt IFRS-standardien mukaan

Tutkimuksen tavoitteena on IFRS-standardien eli uusien kansainvälisten raportointistandardien tuomien muutosten selvittäminen koskien konsernitilinpäätöksen yhdistelyjä. Tutkimusmenetelmä on normatiivinen, teoreettinen ja kvalitatiivinen. IAS/IFRS (International Accounting Standards / International Financial Reporting Standards eli kansainväliset raportointistandardit) tulee pakolliseksi pörssiyrityksille 1.1.2005 alkaen Euroopan Unionin alueella. IAS/IFRS:n mukaan tytäryritykset yhdistellään hankintamenomenetelmällä, osakkuusyritykset pääomaosuusmenetelmällä ja yhteisyritykset suhteellisella yhdistelyllä. Yritysten yhteenliittymät – standardi on olennaisesti uudistettu 31.3.2004. Pooling-menetelmä kiellettiin kokonaan. Hankintamenomenetelmässä kaikki yksilöitävissä olevat varat ja velat arvostetaan käypiin arvoihin. Aineettomien hyödykkeiden ryhmittelyssä on tapahtunut muutoksia. Yksilöitävissä olevat aineettomat hyödykkeet, esimerkiksi asiakassuhteet, aktivoidaan taseeseen ja poistetaan. Aineettomat hyödykkeet, joille ei ole määriteltävissä rajallista käyttöikää, tulee testata pakollisilla arvonalentumistestauksella. Siihen ryhmään kuuluu esimerkiksi liikearvo.

A Method for Estimating Short-term Profitability, Case Stora Enso Packaging Boards

Tutkimuksen tavoitteena oli rakentaa case yritykselle malli lyhyen aikavälin kannattavuuden estimointia varten. Tutkimusmetodi on konstruktiivinen, ja malli kehitettiin laskentaihmisten avustuksella. Teoriaosassa käytiin kirjallisuuskatsauksen avulla läpi kannattavuutta, budjetointia sekä itse ennustamista. Teoriaosassa pyrittiin löytämään sellaisia menetelmiä, joita voitaisiin käyttää lyhyen aikavälin kannattavuuden estimoinnissa. Rakennettavalle mallille asetettujen vaatimusten mukaan menetelmäksi valittiin harkintaan perustuva menetelmä (judgmental). Tutkimuksen mukaan kannattavuuteen vaikuttaa myyntihinta ja –määrä, tuotanto, raaka-aineiden hinnat ja varaston muutos. Rakennettu malli toimii kohdeyrityksessä kohtalaisen hyvin ja huomattavaa on se, että eri tehtaiden ja eri koneiden väliset erot saattavat olla kohtuullisen suuret. Nämä erot johtuvat pääasiassa tehtaan koosta ja mallien erilaisuudesta. Mallin käytännön toimivuus tulee kuitenkin parhaiten selville silloin, kun se on laskentaihmisten käytössä. Ennustamiseen liittyy kuitenkin aina omat ongelmansa ja uudetkaan menetelmät eivät välttämättä poista näitä ongelmia.

Evaluation and realisation of a market entry method: The entry of a small high technology company into the British construction software markets

Tutkielman tavoitteena on tutkia, mikä olisi parhaiten case-yritykselle sopiva menetelmä tulla tekemään kauppaa ulkomaan markkinoille. Kaikki yleiset kansainvälisille markkinoilletulomenetelmät esitetään ja niiden edut ja haitat tuodaan esille. Selvittäessä tehtävänantajayrityksen resurssit, odotukset ja vaatimukset todetaan, että yhteistyössä tehtävä markkinoilletulo on pätevin vaihtoehto. Tämän jälkeen valitaan parhaiten tarkoitukseen sopiva yritys ennalta valitusta yritysvaihtoehtojen ryhmästä ja testataan tämän yrityksen yhteistyösopivuus case-yrityksen kanssa. Yritysten välinen yhteistyösopivuus arvioidaan analysoimalla yritykset haastattelujen avulla ja tutkielmassa esitettyjen teorioiden avulla. Sopivuus todetaan hyväksi, kattaen 71 prosenttia analysoiduista kohdista. Kaksikymmentäyhdeksän prosenttia kohdista todetaan kohdiksi, joissa yritysten välinen yhteisymmärrys ei ole toimeksiantajayrityksen minimivaatimukset täyttävää. Näitä kohtia tullaan käyttämään suunnittelun pohjana kun suunnitellaan jatkoneuvotteluja yhteistyön käynnistämiseksi.

Tutkielmassa käytetty tutkimusmenetelmä on lainoppi. Tutkimusta varten on myös haastateltu alan asiantuntijoita niin ulosotto- kuin konkurssirealisointeihin liittyen. Työn tuloksissa esitetään keskeiset erottavat tekijät yritysomaisuuden realisoinnissa ulosotossa ja konkurssissa. Nämä viisi erottavaa tekijää ovat menettelyjen välinen kilpailullinen suhde, jako-osuus, päätäntävalta omaisuuden myynnissä, myyntitavat ja vakuusoikeuden pysyvyys myynnissä.

Proportionality and Party Success in Europe

This thesis consists of four articles and an introductory section. The main research questions in all the articles are about proportionality and party success in Europe, at European, national or district levels. Proportionality in this thesis denotes the proximity of seat shares parties receive compared to their respective vote shares, after the electoral system’s allocation process. This proportionality can be measured through numerous indices that illustrate either the overall proportionality of an electoral system or a particular election. The correspondence of a single party’s seat shares to its vote shares can also be measured. The overall proportionality is essential in three of the articles (1, 2 and 4), where the system’s performance is studied by means of plots. In article 3, minority party success is measured by advantage-ratios that reveal single party’s winnings or losses in the votes to seat allocation process. The first article asks how proportional are the European parliamentary (EP) electoral systems, how do they compare with results gained from earlier studies and how do the EP electoral systems treat different sized parties. The reasons for different outcomes are looked for in explanations given by traditional electoral studies i.e. electoral system variables. The countries studied (EU15) apply electoral systems that vary in many important aspects, even though a certain amount of uniformity has been aspired to for decades. Since the electoral systems of the EP elections closely resemble the national elections, the same kinds of profiles emerge as in the national elections. The electoral systems indeed treat the parties differentially and six different profile types can be found. The counting method seems to somewhat determine the profile group, but the strongest variables determining the shape of a countries’ profile appears to be the average district magnitude and number of seats allocated to each country. The second article also focuses on overall proportionality performance of an electoral system, but here the focus is on the impact of electoral system changes. I have developed a new method of visualizing some previously used indices and some new indices for this purpose. The aim is to draw a comparable picture of these electoral systems’ changes and their effects. The cases, which illustrate this method, are four elections systems, where a change has occurred in one of the system variables, while the rest remained unchanged. The studied cases include the French, Greek and British European parliamentary systems and the Swedish national parliamentary system. The changed variables are electoral type (plurality changed to PR in the UK), magnitude (France splitting the nationwide district into eight smaller districts), legal threshold (Greece introducing a three percent threshold) and counting method (d’Hondt was changed to modified Sainte-Laguë in Sweden). The radar plots from elections after and before the changes are drawn for all country cases. When quantifying the change, the change in the plots area that is created has also been calculated. Using these radar plots we can observe that the change in electoral system type, magnitude, and also to some extent legal threshold had an effect on overall proportionality and accessibility for small parties, while the change between the two highest averages counting method had none. The third article studies the success minority parties have had in nine electoral systems in European heterogeneous countries. This article aims to add more motivation as to why we should care how different sized parties are treated by the electoral systems. Since many of the parties that aspire to represent minorities in European countries are small, the possibilities for small parties are highlighted. The theory of consociational (or power-sharing) democracy suggests that, in heterogeneous societies, a proportional electoral system will provide the fairest treatment of minority parties. The OSCE Lund Recommendations propose a number of electoral system features, which would improve minority representation. In this article some party variables, namely the unity of the minority parties and the geographical concentration of the minorities were included among possible explanations. The conclusions are that the central points affecting minority success were indeed these non-electoral system variables rather than the electoral system itself. Moreover, the size of the party was a major factor governing success in all the systems investigated; large parties benefited in all the studied electoral systems. In the fourth article the proportionality profiles are again applied, but this time to district level results in Finnish parliamentary elections. The level of proportionality distortion is also studied by way of indices. The average magnitudes during the studied periodrange from 7.5 to 26.2 in the Finnish electoral districts and this opens up unequal opportunities for parties in different districts and affects the shape of the profiles. The intra-country case allows the focus to be placed on the effect of district magnitude, since all other electoral systems are kept constant in an intra-country study. The time span in the study is from 1962 to 2007, i.e. the time that the districts have largely been the same geographically. The plots and indices tell the same story, district magnitude and electoral alliances matter. The district magnitude is connected to the overall proportionality of the electoral districts according to both indices, and the profiles are, as expected, also closer to perfect proportionality in large districts. Alliances have helped some small parties to gain a much higher seat share than their respective vote share and these successes affect some of the profiles. The profiles also show a consistent pattern of benefits for the small parties who ally with the larger parties.

Flexible Multibody Simulation Approach in the Dynamic Analysis of Bone Strains Activity

The objective of this study is to show that bone strains due to dynamic mechanical loading during physical activity can be analysed using the flexible multibody simulation approach. Strains within the bone tissue play a major role in bone (re)modeling. Based on previous studies, it has been shown that dynamic loading seems to be more important for bone (re)modeling than static loading. The finite element method has been used previously to assess bone strains. However, the finite element method may be limited to static analysis of bone strains due to the expensive computation required for dynamic analysis, especially for a biomechanical system consisting of several bodies. Further, in vivo implementation of strain gauges on the surfaces of bone has been used previously in order to quantify the mechanical loading environment of the skeleton. However, in vivo strain measurement requires invasive methodology, which is challenging and limited to certain regions of superficial bones only, such as the anterior surface of the tibia. In this study, an alternative numerical approach to analyzing in vivo strains, based on the flexible multibody simulation approach, is proposed. In order to investigate the reliability of the proposed approach, three 3-dimensional musculoskeletal models where the right tibia is assumed to be flexible, are used as demonstration examples. The models are employed in a forward dynamics simulation in order to predict the tibial strains during walking on a level exercise. The flexible tibial model is developed using the actual geometry of the subject’s tibia, which is obtained from 3 dimensional reconstruction of Magnetic Resonance Images. Inverse dynamics simulation based on motion capture data obtained from walking at a constant velocity is used to calculate the desired contraction trajectory for each muscle. In the forward dynamics simulation, a proportional derivative servo controller is used to calculate each muscle force required to reproduce the motion, based on the desired muscle contraction trajectory obtained from the inverse dynamics simulation. Experimental measurements are used to verify the models and check the accuracy of the models in replicating the realistic mechanical loading environment measured from the walking test. The predicted strain results by the models show consistency with literature-based in vivo strain measurements. In conclusion, the non-invasive flexible multibody simulation approach may be used as a surrogate for experimental bone strain measurement, and thus be of use in detailed strain estimation of bones in different applications. Consequently, the information obtained from the present approach might be useful in clinical applications, including optimizing implant design and devising exercises to prevent bone fragility, accelerate fracture healing and reduce osteoporotic bone loss.

On Commutation and Conjugacy of Rational Languages and the Fixed Point Method

The research on language equations has been active during last decades. Compared to the equations on words the equations on languages are much more difficult to solve. Even very simple equations that are easy to solve for words can be very hard for languages. In this thesis we study two of such equations, namely commutation and conjugacy equations. We study these equations on some limited special cases and compare some of these results to the solutions of corresponding equations on words. For both equations we study the maximal solutions, the centralizer and the conjugator. We present a fixed point method that we can use to search these maximal solutions and analyze the reasons why this method is not successful for all languages. We give also several examples to illustrate the behaviour of this method.

Radio Frequency Measurement Method for Detecting Bearing Currents in Induction Motors

Induction motors are widely used in industry, and they are generally considered very reliable. They often have a critical role in industrial processes, and their failure can lead to significant losses as a result of shutdown times. Typical failures of induction motors can be classified into stator, rotor, and bearing failures. One of the reasons for a bearing damage and eventually a bearing failure is bearing currents. Bearing currents in induction motors can be divided into two main categories; classical bearing currents and inverter-induced bearing currents. A bearing damage caused by bearing currents results, for instance, from electrical discharges that take place through the lubricant film between the raceways of the inner and the outer ring and the rolling elements of a bearing. This phenomenon can be considered similar to the one of electrical discharge machining, where material is removed by a series of rapidly recurring electrical arcing discharges between an electrode and a workpiece. This thesis concentrates on bearing currents with a special reference to bearing current detection in induction motors. A bearing current detection method based on radio frequency impulse reception and detection is studied. The thesis describes how a motor can work as a “spark gap” transmitter and discusses a discharge in a bearing as a source of radio frequency impulse. It is shown that a discharge, occurring due to bearing currents, can be detected at a distance of several meters from the motor. The issues of interference, detection, and location techniques are discussed. The applicability of the method is shown with a series of measurements with a specially constructed test motor and an unmodified frequency-converter-driven motor. The radio frequency method studied provides a nonintrusive method to detect harmful bearing currents in the drive system. If bearing current mitigation techniques are applied, their effectiveness can be immediately verified with the proposed method. The method also gives a tool to estimate the harmfulness of the bearing currents by making it possible to detect and locate individual discharges inside the bearings of electric motors.

The suggested processing of the data collected by SEM consists of several stages and takes into account different aspects affecting the SEM image. The calibration method doesn’t pretend to be precise but at the same time it gives the basics of potential distribution when the different biasing voltages applied to the detector.

Toimitustäsmällisyyden suunnittelumenetelmä

Tutkimuksen ongelma on toimitusten ajallisen täsmällisyyden heikkeneminen kuljetuspolkujen pidentyessä ja erillisten suoritteitten lukumäärän kasvaessa. Näin usein tapahtuu toiminnan kansainvälistyessä. Tutkimuksen tavoitteena on kehittää menetelmä, jolla toimitusten ajallista täsmällisyyttä voidaan suunnitella ja ohjata sekä sen tavoitteet saavuttaa yllä todetusta kehityksestä huolimatta. Aluksi tutkimuksessa on jäsennetty toimitustäsmällisyyden nivoutumista yritys ja markkinointistrategioiden sekä tavoitteiden kokonaisuuteen. Täsmällisyyden merkitystä on myös tarkasteltu yleisesti yritysten kilpailutekijänä. Seuraavaksi on kehitetty interaktiivinen menetelmä, jonka avulla voidaan suunnitella yksittäisen toimituksen ajallista täsmällisyyttä. Toimituksen suoritteet ja niiden vaihtoehdot on kuvattu kvantifioituna, suunnattuna graafina eli verkkona. Ensin on tarkasteltu tilannetta, jossa suoritteiden kestot ovat vakiot ja sitten suoritteiden keston hajonnan huomioon ottavaa menetelmää, jonka avulla on löydettävissä kustannuksiltaan halvin, riittävän täsmällinen ja luotettava ratkaisu. Menetelmän soveltamista on tarkasteltu yleisesti sekä tulo että lähtölogistiikassa, dynaamisessa toimitussuoritetta koskevassa paatoksen teossa ja erilaisissa erityistapauksissa. Täsmällisyystavoitteitten asettamista ja muuttujia on tarkasteltu yleisesti ja käytännön soveltamisen kannalta. Käytännön soveltamista on kokeiltu valitun kohdeyrityksen esimerkkitilanteessa. Menetelmän toimivuutta on testattu simuloimalla sen ja perinteisesti suunniteltujen tehdastoimitusten sekä paikallisvarastosta tehtävien toimitusten tuloksia ja kustannuksia sekä vertaamalla niitä keskenään. Analyysin lopuksi on tarkasteltu esimerkkitilannetta logistisena kokonaisuutena lisäämällä vertailuun muitten kustannuskomponenttien ja lisäarvon vaikutus. Lopussa on käsitelty menetelmän käytännön soveltuvuusprofiilia ja jatkotutkimusaiheita. Yhteenvetona on todettu kehitetyn menetelmän tekevän täsmällisyyttä korostavan toimitusstrategian luotettavan toteuttamisen mahdolliseksi. Sen on taas todettu voivan olla edullinen vaihtoehto, jos täsmällisyydellä on markkina arvoa ja merkitystä pitkän tähtäimen menestystekijänä.

Defining a Performance Measurement System for Technology Marketing Team by Using the Balanced Scorecard Method

This thesis was produced for the Technology Marketing unit at the Nokia Research Center. Technology marketing was a new function at Nokia Research Center, and needed an established framework with the capacity to take into account multiple aspects for measuring the team performance. Technology marketing functions had existed in other parts of Nokia, yet no single method had been agreed upon for measuring their performance. The purpose of this study was to develop a performance measurement system for Nokia Research Center Technology Marketing. The target was that Nokia Research Center Technology Marketing had a framework for separate metrics; including benchmarking for starting level and target values in the future planning (numeric values were kept confidential within the company). As a result of this research, the Balanced Scorecard model of Kaplan and Norton, was chosen for the performance measurement system for Nokia Research Center Technology Marketing. This research selected the indicators, which were utilized in the chosen performance measurement system. Furthermore, performance measurement system was defined to guide the Head of Marketing in managing Nokia Research Center Technology Marketing team. During the research process the team mission, vision, strategy and critical success factors were outlined.
