LiDAR is an advanced remote sensing technology with many applications, including forest inventory. The most common type is ALS (airborne laser scanning). The method is successfully utilized in many developed markets, where it is replacing traditional forest inventory methods. However, it is innovative for Russian market, where traditional field inventory dominates. ArboLiDAR is a forest inventory solution that engages LiDAR, color infrared imagery, GPS ground control plots and field sample plots, developed by Arbonaut Ltd. This study is an industrial market research for LiDAR technology in Russia focused on customer needs. Russian forestry market is very attractive, because of large growing stock volumes. It underwent drastic changes in 2006, but it is still in transitional stage. There are several types of forest inventory, both with public and private funding. Private forestry enterprises basically need forest inventory in two cases – while making coupe demarcation before timber harvesting and as a part of forest management planning, that is supposed to be done every ten years on the whole leased territory. The study covered 14 companies in total that include private forestry companies with timber harvesting activities, private forest inventory providers, state subordinate companies and forestry software developer. The research strategy is multiple case studies with semi-structured interviews as the main data collection technique. The study focuses on North-West Russia, as it is the most developed Russian region in forestry. The research applies the Voice of the Customer (VOC) concept to elicit customer needs of Russian forestry actors and discovers how these needs are met. It studies forest inventory methods currently applied in Russia and proposes the model of method comparison, based on Multi-criteria decision making (MCDM) approach, mainly on Analytical Hierarchy Process (AHP). Required product attributes are classified in accordance with Kano model. The answer about suitability of LiDAR technology is ambiguous, since many details should be taken into account.

Optimization of quantum measurement processes has a pivotal role in carrying out better, more accurate or less disrupting, measurements and experiments on a quantum system. Especially, convex optimization, i.e., identifying the extreme points of the convex sets and subsets of quantum measuring devices plays an important part in quantum optimization since the typical figures of merit for measuring processes are affine functionals. In this thesis, we discuss results determining the extreme quantum devices and their relevance, e.g., in quantum-compatibility-related questions. Especially, we see that a compatible device pair where one device is extreme can be joined into a single apparatus essentially in a unique way. Moreover, we show that the question whether a pair of quantum observables can be measured jointly can often be formulated in a weaker form when some of the observables involved are extreme. Another major line of research treated in this thesis deals with convex analysis of special restricted quantum device sets, covariance structures or, in particular, generalized imprimitivity systems. Some results on the structure ofcovariant observables and instruments are listed as well as results identifying the extreme points of covariance structures in quantum theory. As a special case study, not published anywhere before, we study the structure of Euclidean-covariant localization observables for spin-0-particles. We also discuss the general form of Weyl-covariant phase-space instruments. Finally, certain optimality measures originating from convex geometry are introduced for quantum devices, namely, boundariness measuring how ‘close’ to the algebraic boundary of the device set a quantum apparatus is and the robustness of incompatibility quantifying the level of incompatibility for a quantum device pair by measuring the highest amount of noise the pair tolerates without becoming compatible. Boundariness is further associated to minimum-error discrimination of quantum devices, and robustness of incompatibility is shown to behave monotonically under certain compatibility-non-decreasing operations. Moreover, the value of robustness of incompatibility is given for a few special device pairs.

The aim of this Master’s Thesis was to examine the determinants of intention and behavior of playing sports betting games in order to explain the intention to play in a more precise way and to be able to understand the behavior of playing. The theory of planned behavior was applied in explaining the intention of young Finnish adults aged 18 to 34. A quantitative research method was applied and an online survey was sent to the students of Lappeenranta University of Technology and to the subscribers of Urheilulehti in order to reach a sample that present the young population of Finland. The theory of the study focused on the theory of planned behavior and its antecedents, attitude towards behavior, subjective norms, perceived behavioral control as well as motivation. By analyzing the data, causal relationships were found through which the explanation of intention was possible. The results showed that attitude towards playing, subjective norms, perceived behavioral control and motivation impact the formation of intention significantly. The results also indicated that intention impacts significantly to the playing frequency.

Diplomityön tavoitteena oli case-yrityksen erään tehtaan korkean käyttöpääoman pienentäminen hankintatoimen toimintatapojen ja työkalujen avulla. Tutkimus on tehty tapaustutkimuksena ja se on rajattu hankintatoimeen, joten tehtaan muiden toimintojen vaikutusta käyttöpääomaan ei ole huomioitu. Aineistoina on käytetty käyttöpääomaa ja hankintatoimea käsitteleviä tieteellisiä artikkeleita ja kirjoja sekä tehtaan hankintatoimessa toimivien henkilöiden haastatteluita. Lisäksi diplomityössä on hyödynnetty yrityksen toiminnanohjausjärjestelmästä saatua tietoa sekä yrityksen taloudellisia raportteja. Teoriaosuudessa tutustuttiin käyttöpääomaan merkitykseen yritystasolla ja toimitusketjussa, hankintatoimen merkittävyyteen yritysten toiminnassa sekä tutkittiin millaisilla työkaluilla ja toimintatavoilla hankintatoimi voi vaikuttaa yrityksen käyttöpääomaan. Empiirisessä osuudessa tutkittiin tiettyjen merkittävien nimikkeiden käyttöpääoman muodostumista ja simuloitiin kuinka paljon käyttöpääomaa olisi muodostunut, mikäli teoriaosuudessa tutkittuja työkaluja ja toimintatapoja olisi hyödynnetty. Diplomityössä tutkittiin myös miten toimittajayhteistyön ja toimittajien kehittämisen avulla voidaan pienentää käyttöpääomaa. Diplomityö osoitti, että hankintatoimi voi vaikuttaa merkittävästi käyttöpääoman muodostumiseen ja hankintatoimen toimintatapoja muuttamalla ja työkaluja hyödyntämällä voidaan käyttöpääomaa vapauttaa yrityksessä merkittävästi.

This master’s thesis considers wholesale company’s inventory value reduction and its effects to the operative working capital. The aim is to reduce inventory value by Enterprise Resource Planning System SAP in a controlled manner and without reducing the service level. This thesis contains a theory chapter of inventory management, operative working capital and benefits of ERP sys-tems in inventory management. These theory chapters are applied to practice, and the result is a lower inventory value in the case company. This releases more operative working capital to other more profitable subjects. With more accurate sales forecasts and by using SAP in the supply chain management average stock value can be reduced by 700 k€ which, in turn, reduces Cash Conversion Cycle by 7 days.

Since financial liberalization in the 1980s, non-profit maximizing, stakeholder-oriented banks have outperformed private banks in Europe. This article draws on empirical research, banking theory and theories of the firm to explain this apparent anomaly for neo-liberal policy and contemporary market-based banking theory. The realization of competitive advantages by alternative banks (savings banks, cooperative banks and development banks) has significant implications for conceptions of bank change, regulation and political economy.

Tämä kandidaatintutkielma tarkastelee, mitkä tekijät vaikuttavat teollisuusyrityksen varastonhallinnan ja materiaalinohjauksen kokonaiskustannuksiin. Kokonaistavoitteena on tunnistaa kohdeyritykselle sopivat varaston- ja materiaalinohjauksen menetelmät sekä tunnistaa kehityskohteita tulevaisuuden kehittämistä varten. Tutkielman teoriaosassa käsitellään varastoinnin motiiveja, kustannustekijöitä ja erilaisia täydennysmenetelmiä sekä esitetään materiaalitarvelaskennan perusteita. Tältä pohjalta tutkielman empiirisessä osiossa tutkitaan kolmen eri raaka-ainetoimittajan osalta tilattavien nimikkeiden vuosikustannusten komponentit erilaisilla vuositilauslukumäärillä ja tilauseräko’oilla. Tuloksena kustannuskomponenttien tarkastelusta saadaan suuntaa antavat vuosikustannukset eri tilausmäärillä tai tilausväleillä. Tulokset pohjautuvat kuitenkin hyvin yksinkertaistettuihin taustaoletuksiin, joten suoraan tulosten pohjalta ei tule toimintatapoja muodostaa. Tutkielman perusteella voidaan todeta, että varastonhallinnan tekijät ovat keskenään ristiriitaisia, mutta oikein valituilla menetelmillä voidaan saavuttaa taloudellisia säästöjä ja kehittää toimintaa sujuvammaksi. Erityisesti materiaalitarvelaskentaan siirtyminen materiaalinhallinnassa ja ajantasainen varastokirjanpito tunnistettiin tärkeiksi jatkokehityskohteiksi.

This paper analyses reasons of the instability of the world monetary system. The author considers this problem from historical and contemporary perspectives. According to presented point of view banknotes and electronic money which replaced gold and silver coins in popular circulation are the most important reason of the instability. There are also proven positive and negative consequences of money instability. Reforms of the world monetary system need agreement within the global collective hegemony of state-powers and transnational corporations.

Textbook theory ignores capital flows: trade determines exchange rates and specialisation. Approaches taking the effects of capital movements adequately into account are needed, and a new theory of economic policy including measures to protect the real economy from external volatility. Equilibrating textbook mechanisms cannot work unless trade-caused surpluses and deficits set exchange rates. To allow orthodox trade theory to work one must hinder capital flows from destroying its very basis, which the IMF and wrong regulatory decisions have done, penalising production and trade. A new, real economy based theory is proposed, a Neoclassical agenda of controlling capital flows and speculation.
