Identifying Critical Business Success Factors of Paperboard Tray

Työn tavoitteena oli kartonkivuoan kriittisten menestystekijöiden ja kilpailuaseman selvittäminen jäähdytettyjen ruokatuotteiden markkinoilla Euroopassa. Kilpailija- ja tavoiteanalyysi suoritettiin kahden suomalaisen pakkaajan kesken. Pakkaajien haastattelut toteutettiin joko henkilökohtaisena tai sähköpostihaastatteluna. Muovi on yleisimmin käytetty jäähdytettyjen ruokatuotteiden pakkausmateriaali. Alumiinivuokien osuus on merkittävä erityisesti laatikkoruokien pakkauksena. Kartonkivuoille on kuitenkin havaittavissa selvää menestyspotentiaalia jäähdytettyjen ruokien pakkauksena. Kartonkivuokien hyvä imago ja edistyksellinen tuotekehitystyö mahdollistavat pakkaajien erityisvaatimuksien täyttämisen ja menestymisen markkinoilla. Kartonkivuoilla on useita ainutlaatuisia kilpailuetu- ja menestystekijöitä, kuten hyvä ulkonäkö ja painojälki. Suurin haaste on saada ruokatuotteiden pakkaajat tietoisiksi kartonkivuokien tuomista pakkausmahdollisuuksista.

Consumption of Fashion Luxury Brands

The main objective of this study is to find out why people buy luxury brands and which factors influence their decisions. The elements of luxury brands as well as motivation, culture and self-concept is researched as being the main factors behind luxury consumption. It was important to conduct this study because the luxury market is growing with a fast pace and it has hardly been research before. This study was conducted as a qualitative research. Theoretical part is based on the literature and on researches conducted before about the matter. Purposeful sampling method was used in empirical part by interviewing designers Jukka Rintala and Hanna Sarén as well as consumers of luxury brands, who work in the fashion industry. Two different viewpoints were chosen in order to research if designers’ and consumers’ thoughts differed. This study shows that the elements of luxury brands are deemed pretty much the same all around the world and also between the designers and consumers interviewed. Exclusivity referring to unique design and “hard to get” as well as good quality meaning superior materials, were mentioned as the most important elements of luxury brands. According to this study motivation behind luxury consumption is to a great extent dependent on the culture where the luxuries are consumed. However, self-concept has the biggest effect on luxury consumption. This study shows that people in individualistic cultures buy luxuries because they want to. People tend to spoil themselves and show off, thus making them feel good when buying luxuries. However, uniqueness is appreciated. On contrast, in collectivistic cultures people buy luxuries because they have to. Social pressure is much greater in Eastern than in Western culture that being the reason wealth is expected show. This study shows that in some cases designers' and consumers' thoughts about luxury consumption differ. Especially, a big gap was found when talking about materialism behind luxury consumption. The designers did not believe it to be the reason behind luxury consumption where consumers strongly did.

Palveluliiketoiminta teknologiateollisuudessa

Tutkimuksen tavoitteena on palveluliiketoimintaan liittyvien hypoteesien esittäminen ja niiden todentaminen case-yrityksen avulla. Differointistrategian merkitys ja sen tuomat mahdollisuudet teknologiateollisuuden palveluliiketoiminnassa ovat työn painopisteinä. Itse palveluliiketoimintaa todennettiin tutkimuksessa erinäisin kysymyksin. Tutkimuksen keskeiset aiheet ovat palveluliiketoiminta, differointistrategia, johon myös arvoketjuajattelu kuuluu vahvasti. Tutkimus on keskittynyt myös palveluliiketoiminnan tuottavuuteen ja kannattavuuteen. Jokaista asiaa on pyritty tarkastelemaan logistiikan näkökannalta, mistä on tehty tutkimuksen viitekehys. Tutkimus perustuu kirjallisuustutkimuksiin, havaintoihin ja haastatteluihin. Casetutkimuksen avulla pyritään todentamaan kirjallisuudesta esille tulleet asiat. Palveluliiketoiminta tarkoittaa lisäarvon tuottamista asiakkaalle. Differointistrategia on olennainen osa palveluliiketoimintaa. Differointistrategia perustuu erikoistumiseen ja ainutlaatuisuuteen. Logistiikan avulle voidaan tuottaa asiakkaalle räätälöityjä palveluja ja se mahdollistaa erikoistumisen, differoitumisen. Palveluliiketoiminnan edut ovat lisäarvon tuotto asiakkaalle joko lisäämällä asiakkaan myyntiä ja/tai luomalla kustannussäästöä. Palveluliiketoiminta vaatii toimittajalta strategian ja tavoitteiden muutosta, mutta ennen kaikkea asennemuutosta ja sitoutumista. Palvelun tuottavuus ja kannattavuus mittarit/näkökulmat tulee yrityksen yleensä muuttaa, sillä perinteiset mittaustavat eivät enää välttämättä sovi palveluliiketoiminnan toiminnan mittaamiseen.

Projektimarkkinoinnin haasteet ja suhteiden tunnistaminen

Tässä tutkimustyössä oli tavoitteena tutkia projektimarkkinointiin liittyviä haasteita, joita Andritz Oy Wood Processing on kohdannut yhdessä sellu- ja paperiteollisuuden projektissa ja kolmessa puupohjaisen biomassavoimalaitoksen projektissa. Työn tarkoitus oli nostaa esille millaisia yhteisiä haasteita näiden tutkittujen projektien välillä on olemassa ja mihin työn kohteena olevan yrityksen tulisi keskittyä projektimarkkinointiprosessissa. Teoriaosiossa käsitellään monipuolisesti projektiliiketoimintaan liittyviä teorioita. Ensimmäiseksi tarkastellaan projektimarkkinointi- ja projektimarkkinointiprosessimalleja. Näiden jälkeen tutkitaan D-U-C-mallia (epäjatkuvuus, ainutkertaisuus ja monimutkaisuus), joka esiintyy hyvin monen tutkijan tutkimuksissa, kun käsitellään projektiliiketoimintaa. Lopuksi teoriaosiossa tarkastellaan asiakassuhteita ja miljööanalyysia projektiliiketoiminnassa. Tutkimuksen empiirisessä ensimmäisessä osiossa käydään läpi projektimarkkinointiin liittyvät haasteet, jotka löytyivät tutkituista tapausesimerkeistä. Tämän jälkeen jokaisesta projektista on laadittu miljöökartoitus, jonka perusteella nähdään projektien miljöiden vaihtelevuus. Viimeisenä asiana empiirisessä osiossa käydään läpi perusteet, jotka vaikuttivat projektitoimittajan valintaan. Teoreettisen ja empiirisen aineiston pohjalta on laadittu yritykselle suosituksia, joiden uskotaan parantavan yrityksen kilpailukykyä projektiliiketoiminnassa. Esiin nousseet asiat projektimarkkinoinnissa ovat monille itsestään selvyyksiä, mutta niiden toteuttamisessa on vielä paljon kehitettävää.

Potential of the Osteoclast’s Proton Pump as a Drug Target in Osteoporosis

Decreasing bone mass during aging predisposes to fractures and it is estimated that every second woman and one in five men will suffer osteoporotic fractures during their lifetime. Bone is an adaptive tissue undergoing continuous remodeling in response to physical and metabolic stimuli. Bone mass decreases through a net negative balance in the bone remodeling process of bone, in which the new bone incompletely replaces the resorbed bone mass. Bone resorption is carried out by the osteoclasts; the bone mineral is solubilized by acidification and the organic matrix is subsequently degraded by proteases. Several classes of drugs are available for prevention of osteoporotic fractures. They act by different mechanisms to increase bone mass, and some of them act mainly as antiresorptives by inhibition of osteoclast formation or their function. Optimally, a drug should act selectively on a specific process, since other processes affected usually result in adverse effects. The purpose of this study was to evaluate whether the osteoclastic vacuolar adenosine trisphosphatases (V-ATPase), which drives the solubilization of bone mineral, can be selectively inhibited despite its ubiquitous cellular functions. The V-ATPase is a multimeric protein composed of 13 subunits of which six possesses two or more isoforms. Selectivity for the osteoclastic V-ATPase could be provided if it has some structural uniqueness, such as a unique isoform combination. The a3 isoform of the 116kDa subunit is inevitable for bone resorption; however, it is also present in, and mainly limited to, the lysosomes of other cells. No evidence of a structural uniqueness of the osteoclastic V-ATPase compared to the lysosomal V-ATPase was found, although this can not yet be excluded. Thus, an inhibitor selective for the a3 isoform would target the lysosomal V-ATPase as well. However, the results suggest that selectivity for bone resorption over lysosomal function can be obtained by two other mechanisms, suggesting that isoform a3 is a valid target. The first is differential compensation; bone resorption depends on the high level of a3 expression, and is not compensated for by other isoforms, while the lower level of a3 in lysosomes of other cells may be partly compensated for. The second mechanism is because the bone resorption process itself is fundamentally different from lysosomal acidification because of the chemistry of bone dissolution and the anatomy of the resorbing osteoclast. By this mechanism, full inhibition of bone resorption is obtained with more than tenfold lower inhibitor concentration than those needed to fully inhibit lysosomal acidification. The two mechanisms are additive. Based on the results, we suggest that bone resorption can be selectively inhibited if VATPase inhibitors that are sufficiently selective for the a3 isoform over the other isoforms are developed.

Animal Lovers, Bridge-Builders, and Supervising Watchdogs: Framing and Civil Society Construction by Japanese Pro-Animal Organizations in the Kansai and Tokyo Areas

Unlike their counterparts in Europe and America, the citizen organizations acting for the well-being of animals in Japan have not received scholarly attention. In this research, I explore the activities of twelve Japanese pro-animal organizations in Tokyo and Kansai area from the perspective of social movement and civil society studies. The concept of a ‘pro-animal organization’ is used to refer generally to the collectives promoting animal well-being. By using the collective action frame analysis and the three core framing tasks – diagnostic, prognostic, and motivational – as the primarily analytical tools, I explore the grievances, tactics, motivational means, constructions of agency and identity as well as framing of civil society articulated in the newsletters and the interviews of the twelve organizations I interviewed in Japan in 2010. As the frame construction is always done in relation to the social and political context, I study how the organizations construct their roles as civil society actors in relation to other actors, such as the state, and the idea of citizen activism. The deficiencies in the animal welfare law and lack of knowledge among the public are identified as the main grievances. The primary tactic to overcome these problems was to educate and inform the citizens and authorities, because most organizations lack the channels to influence politically. The audiences were mostly portrayed as either ignorant bystanders or potential adherents. In order to motivate people to join their cause and to enforce the motivation within the organization, the organizations emphasized their uniqueness, proved their efficiency, claimed credit and celebrated even small improvements. The organizations tended to create three different roles for citizen pro-organizations in civil society: reactive, apolitical and emphatic animal lovers concentrating on saving individual animals, proactive, educative bridge-builders seeking to establish equal collaborative relations with authorities, and corrective, supervising watchdogs demanding change in delinquencies offending animal rights. Based on the results of this research, I suggest that by studying how and why the different relations between civil society and the governing actors of the state are constructed, a more versatile approach to citizens’ activism in its context can be achieved.

On state and parameter estimation in chaotic systems

State-of-the-art predictions of atmospheric states rely on large-scale numerical models of chaotic systems. This dissertation studies numerical methods for state and parameter estimation in such systems. The motivation comes from weather and climate models and a methodological perspective is adopted. The dissertation comprises three sections: state estimation, parameter estimation and chemical data assimilation with real atmospheric satellite data. In the state estimation part of this dissertation, a new filtering technique based on a combination of ensemble and variational Kalman filtering approaches, is presented, experimented and discussed. This new filter is developed for large-scale Kalman filtering applications. In the parameter estimation part, three different techniques for parameter estimation in chaotic systems are considered. The methods are studied using the parameterized Lorenz 95 system, which is a benchmark model for data assimilation. In addition, a dilemma related to the uniqueness of weather and climate model closure parameters is discussed. In the data-oriented part of this dissertation, data from the Global Ozone Monitoring by Occultation of Stars (GOMOS) satellite instrument are considered and an alternative algorithm to retrieve atmospheric parameters from the measurements is presented. The validation study presents first global comparisons between two unique satellite-borne datasets of vertical profiles of nitrogen trioxide (NO3), retrieved using GOMOS and Stratospheric Aerosol and Gas Experiment III (SAGE III) satellite instruments. The GOMOS NO3 observations are also considered in a chemical state estimation study in order to retrieve stratospheric temperature profiles. The main result of this dissertation is the consideration of likelihood calculations via Kalman filtering outputs. The concept has previously been used together with stochastic differential equations and in time series analysis. In this work, the concept is applied to chaotic dynamical systems and used together with Markov chain Monte Carlo (MCMC) methods for statistical analysis. In particular, this methodology is advocated for use in numerical weather prediction (NWP) and climate model applications. In addition, the concept is shown to be useful in estimating the filter-specific parameters related, e.g., to model error covariance matrix parameters.

Accuracy improvement of a demand forecasting model

This research concerns different statistical methods that assist to increase the demand forecasting accuracy of company X’s forecasting model. Current forecasting process was analyzed in details. As a result, graphical scheme of logical algorithm was developed. Based on the analysis of the algorithm and forecasting errors, all the potential directions for model future improvements in context of its accuracy were gathered into the complete list. Three improvement directions were chosen for further practical research, on their basis, three test models were created and verified. Novelty of this work lies in the methodological approach of the original analysis of the model, which identified its critical points, as well as the uniqueness of the developed test models. Results of the study formed the basis of the grant of the Government of St. Petersburg.

The Determinants of Financial Leverage of Large Publicly Listed Companies - Evidence from Nordic Telecom Sector

This thesis examines the determinants of financial leverage ratio of large publicly listed companies within Nordic Telecom sector. The study is done as a case study and it covers 5 case companies headquartered in Nordic countries during period of 2002 - 2014 and by using restated values of quarterly observations from each case company’s interim reports. The chosen hypotheses are tested with multiple linear regressions firm by firm. The Findings of the study showed that uniqueness of Telecom sector and the region of our sample could not provide us unequivocal determinants of leverage ratio within the sector. However, e.g. Pecking order theory’s statement of Liquidity was widely confirmed by 3 out of 5 case companies which is worth to be taken into account in the big picture. The findings also showed that theories and earlier empirical evidence are confirmed by our case companies individually and non-systematically. Though Telecom sector is considered as quite unique industry and we did not discover absolute common relationships that would have held through all the Nordic case companies, we got unique and valuable evidence to conduct the research of this sector in future.
