Persistent organic pollutants in sediments and fish from Lake Victoria, Uganda

This thesis describes the occurrence and sources of selected persistent organic pollutants (POPs) such as polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and hexachlorocyclohexanes (HCHs) in the northern watershed of Lake Victoria. Sediments and fish were collected from three highly polluted embayments (i.e. Murchison Bay, Napoleon Gulf and Thurston Bay) of the lake. The analysis for PCDD/Fs, PCBs and PBDEs was done using a high resolution mass spectrometer coupled to a gas chromatograph (GC), and a GC equipped with an electron capture detector was used for HCHs. Total (Σ) PCDD/Fs, PCBs and PBDEs in sediments ranged from 3.19 to 478, 313 to 4325 and 60.8 to 179 pg g-1 dry weight (dw), respectively. The highest concentrations of pollutants were found at sites close to industrial areas and wastewater discharge points. The maximum concentrations of PCDD/Fs, PCBs, PBDEs and HCHs in fish muscle homogenates were 49, 779, 495 and 45,900 pg g-1 wet weight (ww), respectively. The concentrations of the pollutants in Nile perch (Lates niloticus) were significantly greater than those in Nile tilapia (Oreochromis niloticus), possibly due to differences in trophic level and dietary feeding habits among fish species. World Health Organization-toxic equivalency quotient (WHO2005-TEQ) values in the sediments were up to 4.24 pg g-1 dw for PCDD/Fs and 0.55 pg TEQ g-1 dw for the 12 dioxin-like PCBs (dl-PCBs). 23.1% of the samples from the Napoleon Gulf were above the interim sediment quality guideline value of 0.85 pg WHO-TEQ g-1 dw set by the Canadian Council for Ministers of the Environment. The WHO2005-TEQs in fish were 0.001-0.16 pg g-1 for PCDD/Fs and 0.001-0.31 pg g-1 ww for dl- PCBs. The TEQ values were within a permissible level of 3.5 pg g−1 ww recommended by the European Commission. Based on the Commission set TEQs and minimum risk level criteria formulated by the Agency for Toxic Substances and Disease Registry, the consumption of fish from Lake Victoria gives no indication of health risks associated to PCDD/Fs and PCBs. Principal component analysis (PCA) indicated that anthropogenic activities such as agricultural straw open burning, medical waste incinerators and municipal solid waste combustors were the major sources of PCDD/Fs in the watershed of Lake Victoria. The ratios of α-/γ-HCH varied from 0.89 to 1.68 suggesting that the highest HCH residues mainly came from earlier usage and fresh γ-HCH (lindane). In the present study, the concentration of POPs in fish were not significantly related to those in sediments, and the biota sediment accumulation factor (BSAF) concept was found to be a poor predictor of the bioavailability and bioaccumulation of environmental pollutants.

Distribution and role of macrophytes in coastal lagoons : implications of critical shifts

Crossroads, crucibles and refuges are three words that may describe natural coastal lagoon environments. The words refer to the complex mix of marine and terrestrial influences, prolonged dilution due to the semi-enclosed nature and the function of a habitat for highly diverse plant and animal communities, some of which are endangered. To attain a realistic picture of the present situation, high vulnerability to anthropogenic impact should be added to the description. As the sea floor in coastal lagoons is usually entirely photic, macrophyte primary production is accentuated compared with open sea environments. There is, however, a lack of proper knowledge on the importance of vegetation for the general functioning of coastal lagoon ecosystems. The aim of this thesis is to assess the role of macrophyte diversity, cover and species identity over temporal and spatial scales for lagoon functions, and to determine which steering factors primarily restrict the qualitative and quantitative composition of vegetation in coastal lagoons. The results are linked to patterns of related trophic levels and the indicative potential of vegetation for assessment of general conditions in coastal lagoons is evaluated. This thesis includes five field studies conducted in flads and glo-flads in the brackish water northern Baltic Sea. Flads and glo-flads are defined as a Baltic variety of coastal lagoons, which due to an inlet threshold and post-glacial landuplift slowly will be isolated from the open sea. This process shrinks inlet size, increases exposure and water retention, and is called habitat isolation. The studied coastal lagoons are situated in the archipelago areas of the eastern coast of Sweden, the Åland Islands and the south-west mainland of Finland, where land-uplift amounts to ca. 5 mm/ per year. Out of 400 evaluated sites, a total of 70 lagoons varying in inlet size, archipelago position and anthropogenic influence to cover for essential environmental variation were chosen for further inventory. Vegetation composition, cover and richness were measured together with several hydrographic and morphometric variables in the lagoons both seasonally and inter-annually to cover for general regional, local and temporal patterns influencing lagoon and vegetation development. On smaller species-level scale, the effects of macrophyte species identity and richness for the fish habitat function were studied by examining the influence of plant interaction on juvenile fish diversity. Thus, the active election of plant monoand polycultures by fish and the diversity of fish in the respective culture were examined and related to plant height and water depth. The lagoons and vegetation composition were found to experience a regime shift initiated by increased habitat isolation along with land-uplift. Vegetation composition altered, richness decreased and cover increased forming a less isolated and more isolated regime, named the vascular plant regime and charophyte regime, respectively according to the dominant vegetation. As total phosphorus in the water, turbidity and the impact of regional influences decreased in parallel, the dominance of charophytes and increasing cover seemed to buffer and stabilize conditions in the charophyte regime and indicated an increased functional role of vegetation for the lagoon ecosystem. The regime pattern was unaffected by geographical differences, while strong anthropogenic impact seemed to distort the pattern due to loss of especially Chara tomentosa L. in the charophyte regime. The regimes were further found unperturbed by short-time temporal fluctuations. In fact the seasonal and inter-annual dynamics reinforced the functional difference between the regimes by the increasing role of vegetation along habitat isolation and the resemblance to lake environments for the charophyte regime. For instance, greater total phosphorus and chlorophyll a concentrations in the water in the beginning of the season in the charophyte regime compared with the vascular plant regime presented a steeper reduction to even lower values than in the vascular plant regime along the season. Despite a regional importance and positive relationship of macrophyte diversity in relation to trophic diversity, species identity was underlined in the results of this thesis, especially with decreasing spatial scale. This result was supported partly by the increased role of charophytes in the functioning of the charophyte regime, but even more explicitly by the species-specific preference of juvenile fish for tall macrophyte monocultures. On a smaller species-level scale, tall plant species in monoculture seemed to be able to increase their length, indicating that negative selection forms preferred habitat structures, which increase fish diversity. This negative relationship between plant and fish diversity suggest a shift in diversity patterns among trohic levels on smaller scale. Thus, as diversity patterns seem complex and diverge among spatial scales, it might be ambiguous to extend the understanding of diversity relationships from one trophic level to the other. All together, the regime shift described here presents similarities to the regime development in marine lagoon environments and shallow lakes subjected to nutrient enrichment. However, due to nutrient buffering by vegetation with increased isolation and water retention as a consequence of the inlet threshold, the development seems opposite to the course along an eutrophication gradient described in marine lagoons lacking an inlet threshold, where the role of vegetation decreases. Thus, the results imply devastating consequences of inlet dredging (decreasing isolation) in terms of vegetation loss and nutrient release, and call for increased conservational supervision. Especially the red listed charophytes would suffer negatively from such interference and the consequences are likely to also deteriorate juvenile fish production. The fact that a new species to Finland, Chara connivens Salzm. Ex. Braun 1835 was discovered during this study further indicates a potential of the lagoons serving as refuges for rare species.

Exiles and Constituents: Baltic Refugees and American Cold War Politics, 1948- 1960

This dissertation explores the complicated relations between Estonian, Latvian, and Lithuanian postwar refugees and American foreign policymakers between 1948 and 1960. There were seemingly shared interests between the parties during the first decade of the Cold War. Generally, Eastern European refugees refused to recognize Soviet hegemony in their homelands, and American policy towards the Soviet bloc during the Truman and Eisenhower administrations sought to undermine the Kremlin’s standing in the region. More specifically, Baltic refugees and State Department officials sought to preserve the 1940 non-recognition policy towards the Soviet annexation of the Baltic States. I propose that despite the seemingly natural convergence of interests, the American experiment of constructing a State-Private network revolving around fostering relations with exile groups was fraught with difficulties. These difficulties ultimately undermined any ability that the United States might have had to liberate the Baltic States from the Soviet Union. As this dissertation demonstrates, Baltic exiles were primarily concerned with preserving a high level of political continuity to the interwar republics under the assumption that they would be able to regain their positions in liberated, democratic societies. American policymakers, however, were primarily concerned with maintaining the non-recognition policy, the framework in which all policy considerations were analyzed. I argue that these two motivating factors created unnecessary tensions in American policy towards the Baltic republics in the spheres of psychological warfare as well as exile unity in the United States and Europe. Despite these shortcomings, I argue that out of the exiles’ failings was born a generation of Baltic constituents that blurred the political legitimacy line between exiles who sought to return home and ethnic Americans who were loyal to the United States. These Baltic constituents played an important role in garnering the support of the United States Congress, starting in the 1950s, but became increasingly influential after the 1956 Hungarian Revolution, despite the seemingly less important role Eastern Europe played in the Cold War. The actions of the Baltic constituents not only prevented the Baltic question from being forever lost in the memory hole of history, but actually created enough political pressure on the State Department that it was impossible to alter the long-standing policy of not recognizing the Soviet annexation of the Baltic States.

From genotype to phenotype : diversity and population structure of Flavobacterium psychrophilum

Flavobacterium psychrophilum is the etiological agent of bacterial cold-water disease (BCWD) causing high fish mortalities and significant economic losses to the freshwater salmonid aquaculture industry around the world. Today BCWD outbreaks are mainly treated with environmentally hazardous antimicrobial agents and alternative preventative measures are urgently needed in order to ensure the well-being of animals and the sustainability of aquaculture. The diversity of pathogenic bacteria challenges the development of universal control strategies and in many cases the pathogen population structure, i.e. the total genetic diversity of the species must be taken into account. This work integrates the tools of modern molecular biology and conventional phenotypic microbiology to gain knowledge about the diversity and population structure of F. psychrophilum. The present work includes genetic characterization of a large collection of isolates collected from diverse origins and years, from aquaculture in a whole region including different countries, and provides the first international validation of a universal multilocus sequence typing (MLST) approach for unambiguous genetic typing of F. psychrophilum. Population structure analyses showed that the global F. psychrophilum population is subdivided into pathogenic species-specific clones, of which one particular genetic lineage, clonal complex CC-ST2, has been responsible for the majority of BCWD outbreaks in rainbow trout (Oncorhynchus mykiss) in European aquaculture facilities over several decades. Genotypic and phenotypic population heterogeneity affecting antimicrobial resistance in F. psychrophilum within BCWD outbreaks was discovered. Specific genotypes were associated with severe infections in farmed rainbow trout and Atlantic salmon (Salmo salar), and in addition to high adherence, antimicrobial resistance was strongly associated with outbreak strains. The study brought additional support for the hypothesis of an epidemic F. psychrophilum population structure, where recombination is an important force for the generation and maintenance of genetic diversity, and a significant contribution towards mapping the genetic diversity of this important fish pathogen. Evidence indicating dissemination of virulent strains with commercial movement of fish and fish products was strengthened.

How Lean Six Sigma and Agile principles optimize ITIL-based processes

Imagine the potential implications of an organization whose business and IT processes are well aligned and are capable of reactively and proactively responding to the external and internal changes. The Philips IT Infrastructure and Operations department (I&O) is undergoing a series of transformation activities to help Philips business keeping up with the changes. I&O would serve a critical function in any business sectors; given that the I&O’s strategy switched from “design, build and run” to “specify, acquire and performance manage”, that function is amplified. In 2013, I&O’s biggest transforming programme I&O Futures engaged multiple interdisciplinary departments and programs on decommissioning legacy processes and restructuring new processes with respect to the Information Technology Internet Library (ITIL), helping I&O to achieve a common infrastructure and operating platform (CI&OP). The author joined I&O Futures in the early 2014 and contributed to the CI&OP release 1, during which a designed model Bing Box and its evaluations were conducted through the lens of six sigma’s structured define-measure-analyze-improve-control (DMAIC) improvement approach. This Bing Box model was intended to firstly combine business and IT principles, namely Lean IT, Agile, ITIL best practices, and Aspect-oriented programming (AOP) into a framework. Secondly, the author implemented the modularized optimization cycles according to the defined framework into Philips’ ITIL-based processes and, subsequently, to enhance business process performance as well as to increase efficiency of the optimization cycles. The unique of this thesis is that the Bing Box model not only provided comprehensive optimization approaches and principles for business process performance, but also integrated and standardized optimization modules for the optimization process itself. The research followed a design research guideline that seek to extend the boundaries of human and organizational capabilities by creating new and innovative artifacts. The Chapter 2 firstly reviewed the current research on Lean Six Sigma, Agile, AOP and ITIL, aiming at identifying the broad conceptual bases for this study. In Chapter 3, we included the process of constructing the Bing Box model. The Chapter 4 described the adoption of Bing Box model: two-implementation case validated by stakeholders through observations and interviews. Chapter 5 contained the concluding remarks, the limitation of this research work and the future research areas. Chapter 6 provided the references used in this thesis.

Collagen binding integrins and cancer testis antigens in prostate cancer and melanoma

Camilla Pelo Collagen Binding Integrins and Cancer Testis Antigens in Prostate Cancer and Melanoma Department of Biochemistry, MediCity Research Laboratory, University of Turku, Finland Annales Universitatis Turkuensis, Painosalama Oy, Turku, Finland 2016 ABSTRACT Prostate cancer is the second most common cancer in men worldwide. The incidence of melanoma, in turn, is increasing faster than any other cancer incidences. In Finland, more than 5000 prostate cancer and 1200 new melanoma cases are diagnosed each year. One approach to further understand the cellular processes involved in prostate cancer and melanoma is to gain better knowledge about alterations in gene expression and their potential impact on the progression of the diseases. This thesis is focused on expression studies in two gene families; integrins and cancer testis antigens (CT antigens), in human prostate adenocarcinoma and advanced human melanoma. Integrins are heterodimeric transmembrane receptors which regulate many important cellular processes such as cell proliferation, migration and survival. CT antigens are frequently expressed in different types of cancers, but are only expressed in testis in healthy individuals. CT antigens are also highly immunogenic proteins. Due to the properties mentioned above, integrins and CT antigens can function as target molecules for the development of cancer diagnostics and drugs. One of the main purposes of this thesis was to study the expression of the four collagen binding integrins α1β1, α2β1, α10β1, α11β1 and the cancer testis antigen 16 (CT16) in cancer cell lines and human tissues of prostate cancer and metastatic melanoma. Additional aims included studies on the biological role of CT16 and the abundance of CT16 in sera of advanced melanoma patients. The prognostic and diagnostic significance of CT16 and the collagen binding integrins were also evaluated. Expression studies on collagen binding integrins and the CT antigen CT16 in melanoma and prostate cancer were limited and the biological role of CT16 was unknown. In this thesis, the expression levels of α2β1 and α11β1 were found to be significantly altered in prostate cancer tissues. Integrin α2β1 decreased gradually during disease progression while α11 was elevated in prostate carcinoma compared to healthy tissues. In advanced melanoma, enhanced levels of α2 were associated with a significant shorter overall survival in advanced melanoma. In this thesis, CT16 was identified as a frequently expressed melanoma CT antigen with an anti-apoptotic function. To conclude, this thesis presents α2β1 and CT16, as potential and promising biomarkers for advanced melanoma. This thesis reports also the first functional study of CT16. Keywords: Collagen binding integrins, α1β1, α2β1, α10β1, α11β1, Cancer Testis antigens, CT16, melanoma, prostate cancer, expression

Macroalgal Defenses Against Herbivory: Causes and Consequences of Intraspecific Variation

In marine benthic communities, herbivores consume a considerable proportion of primary producer biomass and, thus, generate selection for the evolution of resistance traits. According to the theory of plant defenses, resistance traits are costly to produce and, consequently, inducible resistance traits are adaptive in conditions of variable herbivory, while in conditions of constant/strong herbivory constitutive resistance traits are selected for. The evolution of resistance plasticity may be constrained by the costs of resistance or lack of genetic variation in resistance. Furthermore, resource allocation to induced resistance may be affected by higher trophic levels preying on herbivores. I studied the resistance to herbivory of a foundation species, the brown alga Fucus vesiculosus. By using factorial field experiments, I explored the effects of herbivores and fish predators on growth and resistance of the alga in two seasons. I explored genetic variation in and allocation costs of resistance traits as well as their chemical basis and their effects on herbivore performance. Using a field experiment I tested if induced resistance spreads via water-borne cues from one individual to another in relevant ecological conditions. I found that in the northern Baltic Sea F. vesiculosus communities, strength of three trophic interactions strongly vary among seasons. The highly synchronized summer reproduction of herbivores promoted their escape from the top-down control of fish predators in autumn. This resulted into large grazing losses in algal stands. In spring, herbivore densities were low and regulated by fish, which, thus,enhanced algal growth. The resistance of algae to herbivory increased with an increase in constitutive phlorotannin content. Furthermore, individuals adopted induced resistance when grazed and when exposed to water-borne cues originating from grazing of conspecific algae both in the laboratory and in field conditions. Induced resistance was adopted to a lesser extent in the presence of fish predators. The results in this thesis indicate that inducible resistance in F. vesiculosus is an adaptation to varying herbivory in the northern Baltic Sea. The costs of resistance and strong seasonality of herbivory have likely contributed to the evolution of this defense strategy. My findings also show that fish predators have positive cascading effects on F. vesiculosus which arise via reduced herbivory but possibly also through reduced resource allocation to resistance. I further found evidence that the spread of resistance via water-borne cues also occurs in ecologically realistic conditions in natural marine sublittoral. Thus, water-borne induction may enable macroalgae to cope with the strong grazing pressure characteristic of marine benthic communities. The results presented here show that seasonality can have pronounced effects on the biotic interactions in marine benthic communities and thereafter influence the evolution of resistance traits in primary producers.

Service Management for Service Desk

Palvelunhallinnan kehittäminen Service Desk ympäristöön johtaa parempaan työnkulun hallintaan. Service Deskin päätehtävänä on toimia ainoana yhteyspisteenä asiakkaalta tietohallinto-osastolle. Jokainen yhteydenottopitää kirjata ja se pitäisi olla jäljitettävissä. Tapahtumien eli insidenttien kirjaaminen tapahtuu pääasiassa Service Desk -funktiossa, joka omistaa niistä jokaisen. Tapahtumien hallintaprosessin tehtävänä on etsiä loppukäyttäjän tai IT-infrastruktuurin monitorointityökalun ilmoittamalle insidentille mahdollisimman nopea ratkaisu. Insidentit saattavat johtaa ongelmiin, jotka käsitellään erillisessä prosessissa. Ongelmien hallintaprosessi yrittää etsiä vikatilanteen pohjimmaisen syyn. Kun pohjimmaisin syy on löytynyt, prosessi lähettää muutospyynnön muutosten hallintaprosessille. Jotta päästään mahdollisimman hyvään tehokkuuteen, pitää määrittää asiakasrajapinta sekä mittarit. ITIL-malli tarjoaa prosessit IT-palvelunhallinnan kehittämiselle. Kansainvälisesti tunnettuna 'de factO' standardina sitä voidaan soveltaa globaaleissa yrityksissä. Tässä työssä keskitytään erään lääkkeiden jakelussa toimivan yrityksen tietohallinto-osaston Help Deskin nykytilan määrittämiseen. Työssä myös kuvataan tietohallinto-osaston tavoitetila, jossa keskitytään Service Deskin IT palvelunhallinnan kehittämiseen. Muut prosessit ja mittarit on kuvattu niiltä osin, jotka tulee huomioida Service Deskin seuraamisen ja ohjaamisen kannalta.

Tiedon jakaminen heterogeenisessa projektiverkostossa

Tutkielman tavoitteena on selvittää, mitkä tekijät vaikuttavat tiedon jakamiseen heterogeenisessa projektiverkostossa. Tutkielma sisältää sekä teoreettisen että empiirisen osan. Teoriaosassa käsitellään kahta pääaihetta: tiedon jakamisen verkostomaista kontekstia ja projektiverkostoon sekä sen toimijoihin liittyviä, tiedon jakamiseen vaikuttavia tekijöitä. Empiirinen osuus sisältää kvalitatiivisen haastattelututkimuksen, missä on kerätty case-projektin toimijoiden mielipiteitä niistä seikoista, jotka vaikuttavat tiedon jakamiseen projektiverkostossa. Tutkielman lopuksi kirjallisuuskatsauksen ja haastattelujen tuloksia on verrattu toisiinsa. Tutkielman tulosten perusteella voidaan todeta, että tiedon jakamiseen vaikuttavat projektiverkoston rakenne, projektikumppaneiden motivaatio, osaaminen ja resurssit, projektintarjoama tiedon jakamisen infrastruktuuri, projektin päämäärän selkeys, projektin toimintaa varten laaditut pelisäännöt, sekä projektikoordinaattorin kyky johtaa ja ohjata projektin toimintaa.

Simulaatiopeli menetelmänä siirtää ikääntyvien hiljaista tietoa. Case: Salon Seudun Osuuspankki

Tutkimuksen tavoitteena oli selvittää, miten simulaatiopeli soveltuu ikääntyvien työntekijöiden hiljaisen tiedon esille tuomiseen ja tiedon siirtämiseen. case - tapauksena tutkimuksessa käytettiin Salon Seudun Osuuspankissapelattua simulaatiopeliä ja tutkimustulokset perustuvat peliin osallistuneiden ko. pankin työntekijöiden näkemyksiin ja mielipiteisiin. Tutkimuksessa selvitettiin miten osallistujat kokevat simulaatiopelin tilanteena, mitkä ovat simulaatiopelin heikkoudet ja vahvuudet hiljaisen tiedon siirrossa sekä millä tavalla simulaatiopeliä tulisi käyttää siirrettäessä hiljaista tietoa. Lisäksi selvitettiin mitä hiljainen tieto pankkityössä on. Tutkimus toteutettiin teemahaastatteluin marraskuussa 2004. Tutkimuksen tuloksena selvisi, että simulaatiopeliä ei nähdä kovin käyttökelpoisena, itsenäisenä hiljaisen tiedon siirron menetelmänä. Merkittävimpinä syinä tähän on simulaatiopelin keinotekoisuus, epäaitous sekä tilanteen jännittävyys. Simulaatiopelin vahvuudeksi hiljaisen tiedon siirrossa koetaan sen erinomainen havainnollistava voima. Simulaatiopeliä voitaisiinkin kokeilla apuna hiljaisen tiedon siirrossa osana pidempää tiedon siirron prosessia.

Esitettyjen toimenpiteiden avulla yrityksen kykyä tarjota kokonaispalvelua ja teknisesti laadukkaita tuotteita käytettäisiin edelleen hyväksi yhteistyökumppaneiden sitouttamisessa ja motivoimisessa.

Sähköisten kuljetustietojen vaikutukset päivittäistavarakaupan pitkässä arvoketjussa

Tutkielman tavoitteena on esittää kustannustehokkaita tapoja lähetystoimintojen ja kuljetustietojen käsittelyyn päivittäistavarakaupan logistiikkakeskuksessa. Tutkielmassa kuvataan case-yrityksen lähettämö- ja kuljetustoimintojen sekä lähtevän tavaravirran seurannan ja rahtilaskutuksen nykytilanne. Tutkimusmenetelmänä on käytetty case-yrityksen avainhenkilöiden teemahaastatteluja sekä erillistä haastattelututkimusta kahdeksalle suurimmalle case-yrityksen käyttämälle kuljetusliikkeelle. Työssä esitellään keskeisimpien kuljetustietojen ja lähettämötoimintojen sähköistämisen edellytyksiä sekä niiden toteutusmahdollisuuksia. Koska lähtevän tavaravirran käsittely manuaalisesti aiheuttaa ylimääräisiä virheitä ja tehottomuutta pitkän arvoketjun eri vaiheissa työllistäen lähettämön, kuljetusliikkeiden, terminaalien ja myymälöiden työntekijöitä, on tutkielmassa esitelty keskeisimmät keinot tehostaa ja automatisoida lähtevien kuljetusyksiköiden käsittelyä. Ratkaisut pohjautuvat lähtevien kuljetusyksiköiden yksilöintiin ja seurantaan. Yksiköiden käsittelyä tehostetaan automatisoimalla yksiköiden tunnistamista ja tiedonsiirtoa. Käytettäviksi työkaluiksi on valittu viivakoodit ja tarvittavat lukijat yksiköiden tunnistamiseen. Sähköisellä rahtikirjalla pyritään paperittomaan lähettämötoimintaan ja sitä kautta automatisoimaan rahtilaskutusta ottamalla käyttöön laskuton maksu. Kuljetustietojen sähköistämisellä voidaan saavuttaa mittavat kustannussäästöt pitkässä arvoketjussa.

Yhteistoiminnan ja tiedon jakamisen kehittäminen

Tässä tutkimustyössä on tavoitteena tutkia UPM-Kymmene Wood Oy:n vaneriliiketoimintaorganisaation lähtölogistiikka- ja myyntiosaston tiedon jakamisen ja yhteistoiminnan nykytilaa ja kartoittaa osastojen tiedontarpeita yhteistoimintaan liittyen. Työn tavoitteena on tämän jälkeen antaa kohdeosastoille ehdotuksia toimenpiteistä ja teknologisista ratkaisuista toiminnan parantamiseen. Työssä esitetään aluksi tietoon ja sen jakamiseen liittyviä käsitteitä. Tämän jälkeen tekstissä luodaan katsaus liiketoimintatietoon ja sen hallintaan. Lisäksi tutkimuksessa tarkastellaan tutkimuksen kohteena olevaa organisaatiota ja kohdeosastoja. Haastatteluiden ja havainnoinnin avulla kerätyn tutkimusaineiston perusteella kohdeosastojen välillä vaihdetaan nykytilassa paljon erilaista asiakkaisiin ja markkinoihin liittyvää tietoa. Tiedon jakaminen ja vaihto perustuu kuitenkin nykytilassa hyvin vahvasti säännöllisen yhteistoiminnan sijaan erillisesti ilmaistuihin tietotarpeisiin. Haastatteluiden perusteella kohdeosastoissa on havaittavissa myös parannustarpeita nykyiseen tiedonkulkuun ja tiedon jakamiseen verrattuna. Annetut kehitysehdotukset koskevat yhteistoiminnan muuntamista säännölliseksi ja keskustelevaksi, olemassa olevien tietojen tehokkaammasta jakamisesta ja nykyisten tietohallintajärjestelmien hyödyntämisestä yhteistoiminnassa uusien järjestelmien luomisen sijaan.
