The objective of this project was to gather all the counters which are used on HSPA performance monitoring. The main purpose was to create a compact packet of HSPA performance counters and radio network monitoring which Ericsson's employees can then use in their daily work. The study includes a short introduction to the architecture of the 3G-radio access network. The HSPA technology and HSPA performance are presented including a functional description of performance counters and KPIs, which are used for performance management and monitoring. The theory part of the study also covers an overview of performance management in OSS-RC. The final part of the study covers an overview of the performance management tools, in-troducing how the counters are represented in these interfaces. MOShell and OSS-RC are tools used in this study. Tools were selected because the MOShell is Ericsson's inter-nal management tool and OSS-RC is a tool designed for customers.

Value chain collaboration has been a prevailing topic for research, and there is a constantly growing interest in developing collaborative models for improved efficiency in logistics. One area of collaboration is demand information management, which enables improved visibility and decrease of inventories in the value chain. Outsourcing of non-core competencies has changed the nature of collaboration from intra-enterprise to cross-enterprise activity, and this together with increasing competition in the globalizing markets have created a need for methods and tools for collaborative work. The retailer part in the value chain of consumer packaged goods (CPG) has been studied relatively widely, proven models have been defined, and there exist several best practice collaboration cases. The information and communications technology has developed rapidly, offering efficient solutions and applications to exchange information between value chain partners. However, the majority of CPG industry still works with traditional business models and practices. This concerns especially companies operating in the upstream of the CPG value chain. Demand information for consumer packaged goods originates at retailers' counters, based on consumers' buying decisions. As this information does not get transferred along the value chain towards the upstream parties, each player needs to optimize their part, causing safety margins for inventories and speculation in purchasing decisions. The safety margins increase with each player, resulting in a phenomenon known as the bullwhip effect. The further the company is from the original demand information source, the more distorted the information is. This thesis concentrates on the upstream parts of the value chain of consumer packaged goods, and more precisely the packaging value chain. Packaging is becoming a part of the product with informative and interactive features, and therefore is not just a cost item needed to protect the product. The upstream part of the CPG value chain is distinctive, as the product changes after each involved party, and therefore the original demand information from the retailers cannot be utilized as such – even if it were transferred seamlessly. The objective of this thesis is to examine the main drivers for collaboration, and barriers causing the moderate adaptation level of collaborative models. Another objective is to define a collaborative demand information management model and test it in a pilot business situation in order to see if the barriers can be eliminated. The empirical part of this thesis contains three parts, all related to the research objective, but involving different target groups, viewpoints and research approaches. The study shows evidence that the main barriers for collaboration are very similar to the barriers in the lower part of the same value chain; lack of trust, lack of business case and lack of senior management commitment. Eliminating one of them – the lack of business case – is not enough to eliminate the two other barriers, as the operational model in this thesis shows. The uncertainty of the future, fear of losing an independent position in purchasing decision making and lack of commitment remain strong enough barriers to prevent the implementation of the proposed collaborative business model. The study proposes a new way of defining the value chain processes: it divides the contracting and planning process into two processes, one managing the commercial parts and the other managing the quantity and specification related issues. This model can reduce the resistance to collaboration, as the commercial part of the contracting process would remain the same as in the traditional model. The quantity/specification-related issues would be managed by the parties with the best capabilities and resources, as well as access to the original demand information. The parties in between would be involved in the planning process as well, as their impact for the next party upstream is significant. The study also highlights the future challenges for companies operating in the CPG value chain. The markets are becoming global, with toughening competition. Also, the technology development will most likely continue with a speed exceeding the adaptation capabilities of the industry. Value chains are also becoming increasingly dynamic, which means shorter and more agile business relationships, and at the same time the predictability of consumer demand is getting more difficult due to shorter product life cycles and trends. These changes will certainly have an effect on companies' operational models, but it is very difficult to estimate when and how the proven methods will gain wide enough adaptation to become standards.

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.

Marketvisio on laatinut Pirkanmaan TE-keskuksen toimeksiannosta Pirkanmaan ICT-alan (informaatio- ja tietoliikenneteknologia) ennakointiselvityksen, jonka keskeisinä tavoitteina on tukea suunnitteilla olevan Pirkanmaan ICT-strategian rakentamista. Tässä ennakointiselvityksessä kuvataan alueellisen ICT-klusterin nykytilaa sekä keskeisiä muutostrendejä vaikutuksineen. Erityinen painoarvo on annettu trendeille, jotka vaikuttavat pirkanmaalaisten ICT-toimittajien suurimpiin asiakasyrityksiin. Erikseen selvityksessä arvioidaan erilaisten julkisten toimijoiden ja niiden rahoittamien verkostojen ja ohjelmien toimivuutta yritysten näkökulmasta. Lopussa luodaan katsaus ICT-alan työvoima- ja osaamistarpeisiin 10-20 vuoden horisontilla. Marketvision esittämät näkemykset perustuvat paitsi kirjallisiin lähteisiin ml. kansainvälisen tutkimusyhtiö Gartnerin tutkimustuloksiin myös syksyllä 2009 tehtyihin henkilökohtaisiin haastatteluihin sekä erikseen toteutettuihin verkkokyselyihin. Nokian toiminta ja vahva läsnäolo Tampereella on vaikuttanut voimakkaasti Pirkanmaan alueen ICT-klusteriin. Tulevaisuudessa telecom-klusterin suhteellinen merkitys alueella kuitenkin todennäköisesti laskee. Toinen suuri alaa koskeva muutos on kansainvälistyminen ja työnjaon globaalit muutokset. Pirkanmaalaisten ICT-yritysten asiakkaat siirtävät ohjelmistoalustoja, ohjelmistoalihankintaa sekä perustuotantoansa halvemman tuotantotason maihin - Suomen ja Pirkanmaan kustannustasolla ei kaikkea työtä enää voida täällä tehdä. Kustannustehokkuus tulee edelleen kasvattamaan rooliaan ja samalla myös osaamisvaatimukset muuttuvat. IT-yritysten roolin muuttuessa on löydettävä uusia toiminta-alueita sekä sopeuduttava uusiin tuotantotapoihin. ICT-yritysten tulevaisuuden toiminnan pääpainoalueina ovat asiakkuuden hoito ja palveluliiketoiminta. Lisäksi verkostoituminen muiden suomalaisten sekä kansainvälisten kumppanien kanssa on yhä tärkeämpää. Ennakointiselvityksessä identifioitiin keskeisiä yhteiskunnallisia ja teknologisia trendejä, jotka tulevat vaikuttamaan Pirkanmaan ICT-klusterin tulevaisuuteen. Vaikutukset toteutuvat lähinnä muutoksina eri asiakasalueiden vaatimuksissa ja tarpeissa sekä toisaalta muuttuneena kilpailutilanteena. Lisäksi ICT-palveluiden tuotantomahdollisuuksissa ja näihin liittyvissä teknologisissa vaihtoehdoissa tullaan kokemaan radikaaleja, nopeasti toteutuvia muutoksia. Eräänä keskeisenä johtopäätöksenä ennakointiselvityksessä on se, että ICT on mukana kaikessa mitä teemme lähitulevaisuudessa, mutta yhä harvemmin se on yksinään merkityksellistä. Tämän vuoksi puhtaasti ICT:n ympärille on Pirkanmaallakin vaarallista perustaa liiketoimintaa ja onnistuneet liikeideat syntyvät usein ICT:n yhdistämisestä muihin aloihin. Perusongelma monilla alkuvaiheen ICT-yrityksillä onkin kontaktien puute ICT-alan ulkopuolelle. Monet yritykset ovat edelleen hyvin teknologiakeskeisiä ja etäällä lopullisten asiakkaiden tarpeista. Teknologiaosaamisen rinnalle olisi ensiarvoisen tärkeää rakentaa vahva ymmärrys asiakkaista ja heitä houkuttelevista tuote- ja palvelukonsepteista. Tulevaisuudessa tuoteja palvelukonseptien ja ideoiden laatu on ainoa kestävä menestystekijä, kun erityisesti massatuotteiden tuottaminen voidaan tehdä halvemman työvoiman maissa. Erilaiset yhteistyömallit, partneroituminen ja kyky toimia ketterästi monimutkaisissa verkostoissa ja modulaaristen tuotteiden kanssa ovat tärkeitä ydinkyvykkyyksiä pirkanmaalaisille ICT-yrityksille, joiden täytyy yhdistää palvelunsa ja tuotteensa muihin komponentteihin osana suurempaa arvoketjua. Pienikin pirkanmaalainen yritys voi toimia tehokkaasti hyvin toimivassa arvoverkossa, mutta yksin on yhä vaikeampaa ja vaikeampaa tuottaa menestyviä tuotteita ja palveluita.

In recent times the packaging industry is finding means to maximize profit. Wood used to be the most advantageous and everyday material for packaging, worktables, counters, constructions, interiors, tools and as materials and utensils in the food companies in the world. The use of wood has declined vigorously, and other materials like plastic, ceramic, stainless steel, concrete, and aluminum have taken its place. One way that the industry could reduce its cost is by finding possibilities of using wood for primary packaging after which it can be safely recycled or burned as a carbon source for energy. Therefore, the main objective of this thesis is to investigate the possibility of press-forming a wood film into primary packaging. In order to achieve the stated objectives, discussion on major characteristics of wood in terms of structure, types and application were studied. Two different wood species, pine and birch were used for the experimental work. These were provided by a local carpentry workshop in Lappeenranta and a workshop in Ruokolahti supervised by Professor Timo Kärki. Laboratory tests were carried out at Lappeenranta University of Technology FMS workshop on Stenhøj EPS40 M hydraulic C-frame press coupled with National Instruments VI Logger and on the Adjustable packaging line machine at LUT Packaging laboratory. The tests succeeded better on the LUT packaging line than on the Stenhoj equipment due to the integrated heating system in the machine. However, there is much work to be done before the quality of a tray produced from the wood film is comparable to that of the wood plastic composite tray.
