Physical habitat characteristics such as stream width, depth, instream cover, and substrate composition are important environmental factors that shape Iowa’s stream fish species assemblages. The Iowa Department of Natural Resources (IDNR) stream biological assessment program collects physical habitat data to help interpret fish assemblage sampling results in order to assess stream health condition and the attainment status of designated aquatic life uses. The quantitative habitat indicators and interpretative guidelines developed in this study are designed for specific applications within the stream bioassessment program. These tools might also be useful to natural resource managers for purposes such as stream habitat improvement prioritization, goal-setting, and performance assessment.

Characterizing the risks posed by nanomaterials is extraordinarily complex because these materials can have a wide range of sizes, shapes, chemical compositions and surface modifications, all of which may affect toxicity. There is an urgent need for a testing strategy that can rapidly and efficiently provide a screening approach for evaluating the potential hazard of nanomaterials and inform the prioritization of additional toxicological testing where necessary. Predictive toxicity models could form an integral component of such an approach by predicting which nanomaterials, as a result of their physico-chemical characteristics, have potentially hazardous properties. Strategies for directing research towards predictive models and the ancillary benefits of such research are presented here.

In the era of fast product development and customized product requirements, the concept of product platform has proven its power in practice. The product platform approach has enabledcompanies to increase the speed of product introductions while simultaneously benefit from efficiency and effectiveness in the development and production activities. The product platforms are technological bases, which can be used to develop several derivative products, and hence, the differentiation can be pushed closer to the product introduction. The product platform development has some specific features, which differ somewhat from the product development of single products. The time horizon is longer, since the product platform¿slife cycle is longer than individual product's. The long time-horizon also proposes higher market risks and the use of new technologies increases the technological risks involved. The end-customer interface might be far away, but there is not a lack of needs aimed at the product platforms ¿ in fact, the product platform development is very much balancing between the varying needs set to it by thederivative products. This dissertation concentrated on product platform development from the internal product lines' perspective of a singlecase. Altogether six product platform development factors were identified: 'Strategic and business fit of product platform', 'Project communication and deliverables', 'Cooperation with product platform development', 'Innovativeness of product platform architecture and features', 'Reliability and quality of product platform', and 'Promised schedules and final product platform meeting the needs'. From the six factors, three were found to influence quite strongly the overall satisfaction, namely 'Strategic and business fit of product platform', 'Reliability and quality of product platform', and 'Promised schedules and final product platform meeting the needs'. Hence, these three factors might be the ones a new product platform development unit should concentrate first in order to satisfy their closest customers, the product lines. The 'Project communication and deliverables' and 'Innovativeness of product platform architecture and features' were weaker contributors to the overall satisfaction. Overall, the factors explained quite well the satisfaction of the product lines with product platform development. Along the research, several interesting aspects about the very basic nature of the product platform development were found. The long time horizon of the product platform development caused challenges in the area of strategic fIT - a conflict between the short-term requirements and long term needs. The fact that a product platform was used as basis of several derivative products resulted into varying needs, and hence the match with the needs and the strategies. The opinions, that the releases of the larger product lines were given higher priorities, give an interesting contribution to the strategy theory of powerand politics. The varying needs of the product lines, the strengths of them as well as large number of concurrent releases set requirements to prioritization. Hence, the research showed the complicated nature of the product platform development in the case unIT - the very basic nature of the product platform development might be its strength (gaining efficiency and effectiveness in product development and product launches) but also the biggest challenge (developing products to meet several needs). As a single case study, the results of this research are not directly generalizable to all the product platform development activities. Instead, the research serves best as a starting point for additional research as well as gives some insights about the factors and challengesof one product development unit.

BACKGROUND: Meticulous steps and procedures are proposed in planning guidelines for the development of comprehensive multiyear plans for national immunization programmes. However, we know very little about whether the real-life experience of those who adopt these guidelines involves following these procedures as expected. Are these steps and procedures followed in practice? We examined the adoption and usage of the guidelines in planning national immunization programmes and assessed whether the recommendations in these guidelines are applied as consistently as intended. METHODS: We gathered information from the national comprehensive multiyear plans developed by 77 low-income countries. For each of the 11 components, we examined how each country applied the four recommended steps of situation analysis, problem prioritization, selection of interventions, and selection of indicators. We then conducted an analysis to determine the patterns of alignment of the comprehensive multiyear plans with those four recommended planning steps. RESULTS: Within the first 3 years following publication of the guidelines, 66 (86%) countries used the tool to develop their comprehensive multiyear plans. The funding conditions attached to the use of these guidelines appeared to influence their rapid adoption and usage. Overall, only 33 (43%) countries fully applied all four recommended planning steps of the guidelines. CONCLUSIONS: Adoption and usage of the guidelines for the development of comprehensive multiyear plans for national immunization programmes were rapid. However, our findings show substantial variation between the proposed planning ideals set out in the guidelines and actual use in practice. A better understanding of factors that influence how recommendations in public health guidelines are applied in practice could contribute to improvements in guidelines design. It could also help adjust strategies used to introduce them into public health programmes, with the ultimate goal of a greater health impact.

Given the cost constraints of the European health-care systems, criteria are needed to decide which genetic services to fund from the public budgets, if not all can be covered. To ensure that high-priority services are available equitably within and across the European countries, a shared set of prioritization criteria would be desirable. A decision process following the accountability for reasonableness framework was undertaken, including a multidisciplinary EuroGentest/PPPC-ESHG workshop to develop shared prioritization criteria. Resources are currently too limited to fund all the beneficial genetic testing services available in the next decade. Ethically and economically reflected prioritization criteria are needed. Prioritization should be based on considerations of medical benefit, health need and costs. Medical benefit includes evidence of benefit in terms of clinical benefit, benefit of information for important life decisions, benefit for other people apart from the person tested and the patient-specific likelihood of being affected by the condition tested for. It may be subject to a finite time window. Health need includes the severity of the condition tested for and its progression at the time of testing. Further discussion and better evidence is needed before clearly defined recommendations can be made or a prioritization algorithm proposed. To our knowledge, this is the first time a clinical society has initiated a decision process about health-care prioritization on a European level, following the principles of accountability for reasonableness. We provide points to consider to stimulate this debate across the EU and to serve as a reference for improving patient management.

OBJECTIVE: Routinely collected health data, collected for administrative and clinical purposes, without specific a priori research questions, are increasingly used for observational, comparative effectiveness, health services research, and clinical trials. The rapid evolution and availability of routinely collected data for research has brought to light specific issues not addressed by existing reporting guidelines. The aim of the present project was to determine the priorities of stakeholders in order to guide the development of the REporting of studies Conducted using Observational Routinely-collected health Data (RECORD) statement. METHODS: Two modified electronic Delphi surveys were sent to stakeholders. The first determined themes deemed important to include in the RECORD statement, and was analyzed using qualitative methods. The second determined quantitative prioritization of the themes based on categorization of manuscript headings. The surveys were followed by a meeting of RECORD working committee, and re-engagement with stakeholders via an online commentary period. RESULTS: The qualitative survey (76 responses of 123 surveys sent) generated 10 overarching themes and 13 themes derived from existing STROBE categories. Highest-rated overall items for inclusion were: Disease/exposure identification algorithms; Characteristics of the population included in databases; and Characteristics of the data. In the quantitative survey (71 responses of 135 sent), the importance assigned to each of the compiled themes varied depending on the manuscript section to which they were assigned. Following the working committee meeting, online ranking by stakeholders provided feedback and resulted in revision of the final checklist. CONCLUSIONS: The RECORD statement incorporated the suggestions provided by a large, diverse group of stakeholders to create a reporting checklist specific to observational research using routinely collected health data. Our findings point to unique aspects of studies conducted with routinely collected health data and the perceived need for better reporting of methodological issues.

Mayflies (Ephemeroptera) are known to generally present a high degree of insular endemism: half of the 28 species known from Corsica and Sardinia are considered as endemic. We sequenced the DNA barcode (a fragment of the mitochondrial COI gene) of 349 specimens from 50 localities in Corsica, Sardinia, continental Europe and North Africa. We reconstructed gene trees of eight genera or species groups representing the main mayfly families. Alternative topologies were built to test if our reconstructions suggested a single or multiple Corsican/Sardinian colonization event(s) in each genus or species group. A molecular clock calibrated with different evolution rates was used to try to link speciation processes with geological events. Our results confirm the high degree of endemism of Corsican and Sardinian mayflies and the close relationship between these two faunas. Moreover, we have evidence that the mayfly diversity of the two islands is highly underestimated as at least six new putative species occur on the two islands. We demonstrated that the Corsican and Sardinian mayfly fauna reveals a complex history mainly related to geological events. The Messinian Salinity Crisis, which is thought to have reduced marine barriers, thus facilitating gene flow between insular and continental populations, was detected as the most important event in the speciation of most lineages. Vicariance processes related to the split and rotation of the Corso-Sardinian microplate had a minor impact as they involved only two genera with limited dispersal and ecological range. Colonization events posterior to the Messinian Salinity Crisis had only marginal effects as we had indication of recent gene flow only in two clades. With very limited recent gene flow and a high degree of endemism, mayflies from Corsica and Sardinia present all the criteria for conservation prioritization.

Tärkeä osa paperiteollisuuden myyntitapahtumaa on tarkistaa tilatun tuotteen saatavuus ja toimittamisen aikataulu. Käytännössä tämä tarkoittaa kuljetusten, tuotannon ja valmistetun materiaalin tarkistamista. Tässä työssä on tehty olemassa olevan vapaan materiaalin tarkistaminen. Materiaalin tarkastus ei ole uusi idea, mutta kapasiteettivarauksen uudelleen toteutus on tehty tulevan ylläpitotyön helpottamiseksi ja järjestelmän suorituskyvyn parantamiseksi. Lisäksi uutta varauslogiikkaa pystytään käyttämään muissakin tuotannonohjausjärjestelmän ohjelmistoissa. Kapasiteettivaraukseen on myös rakennettu uusi kustannuspohjainen priorisointijärjestelmä, ja mietitty kuinka tätä olisi tulevaisuudessa helppo jalostaa. Erityishuomiota on kiinnitetty toiminnan läpinäkyvyyteen eli siihen, että tarkistuslogiikka kertoo syyt eri materiaalin hylkäämiseen. Työn yhteydessä on analysoitu materiaalivarauksen aiheuttamaa kuormaa järjestelmässä ja mietitty eri tekniikoita suorituskyvyn parantamiseksi.

The aim of this Thesis is to study how to manage the front-end of the offering planning process. This includes actual process development and methods to gather and analyze information to achieve the best outcome in customer oriented product offering. Study is carried out in two parts: theoretical part and company related part. Theoretical framework is created introducing different types of approaches to manage product planning processes. Products are seen as platforms and they are broken down to subsystems to show different parts of the development. With the help of the matrix-based approaches product platform related information is gathered and analyzed. In this kind of analysis business/market drivers and cus-tomer/competitor information are connected with product subsystems. This gives possibilities to study product gaps/needs and possible future ideas/scenarios in different customer segments. Company related part consists of offering planning process development in real company environment. Process formation includes documents and tools that guide planning from the information gathering to the prioritization and decision making.

Genetic diversity is one of the levels of biodiversity that the World Conservation Union (IUCN) has recognized as being important to preserve. This is because genetic diversity is fundamental to the future evolution and to the adaptive flexibility of a species to respond to the inherently dynamic nature of the natural world. Therefore, the key to maintaining biodiversity and healthy ecosystems is to identify, monitor and maintain locally-adapted populations, along with their unique gene pools, upon which future adaptation depends. Thus, conservation genetics deals with the genetic factors that affect extinction risk and the genetic management regimes required to minimize the risk. The conservation of exploited species, such as salmonid fishes, is particularly challenging due to the conflicts between different interest groups. In this thesis, I conduct a series of conservation genetic studies on primarily Finnish populations of two salmonid fish species (European grayling, Thymallus thymallus, and lake-run brown trout, Salmo trutta) which are popular recreational game fishes in Finland. The general aim of these studies was to apply and develop population genetic approaches to assist conservation and sustainable harvest of these populations. The approaches applied included: i) the characterization of population genetic structure at national and local scales; ii) the identification of management units and the prioritization of populations for conservation based on evolutionary forces shaping indigenous gene pools; iii) the detection of population declines and the testing of the assumptions underlying these tests; and iv) the evaluation of the contribution of natural populations to a mixed stock fishery. Based on microsatellite analyses, clear genetic structuring of exploited Finnish grayling and brown trout populations was detected at both national and local scales. Finnish grayling were clustered into three genetically distinct groups, corresponding to northern, Baltic and south-eastern geographic areas of Finland. The genetic differentiation among and within population groups of grayling ranged from moderate to high levels. Such strong genetic structuring combined with low genetic diversity strongly indicates that genetic drift plays a major role in the evolution of grayling populations. Further analyses of European grayling covering the majority of the species’ distribution range indicated a strong global footprint of population decline. Using a coalescent approach the beginning of population reduction was dated back to 1 000-10 000 years ago (ca. 200-2 000 generations). Forward simulations demonstrated that the bottleneck footprints measured using the M ratio can persist within small populations much longer than previously anticipated in the face of low levels of gene flow. In contrast to the M ratio, two alternative methods for genetic bottleneck detection identified recent bottlenecks in six grayling populations that warrant future monitoring. Consistent with the predominant role of random genetic drift, the effective population size (Ne) estimates of all grayling populations were very low with the majority of Ne estimates below 50. Taken together, highly structured local populations, limited gene flow and the small Ne of grayling populations indicates that grayling populations are vulnerable to overexploitation and, hence, monitoring and careful management using the precautionary principles is required not only in Finland but throughout Europe. Population genetic analyses of lake-run brown trout populations in the Inari basin (northernmost Finland) revealed hierarchical population structure where individual populations were clustered into three population groups largely corresponding to different geographic regions of the basin. Similar to my earlier work with European grayling, the genetic differentiation among and within population groups of lake-run brown trout was relatively high. Such strong differentiation indicated that the power to determine the relative contribution of populations in mixed fisheries should be relatively high. Consistent with these expectations, high accuracy and precision in mixed stock analysis (MSA) simulations were observed. Application of MSA to indigenous fish caught in the Inari basin identified altogether twelve populations that contributed significantly to mixed stock fisheries with the Ivalojoki river system being the major contributor (70%) to the total catch. When the contribution of wild trout populations to the fisheries was evaluated regionally, geographically nearby populations were the main contributors to the local catches. MSA also revealed a clear separation between the lower and upper reaches of Ivalojoki river system – in contrast to lower reaches of the Ivalojoki river that contributed considerably to the catch, populations from the upper reaches of the Ivalojoki river system (>140 km from the river mouth) did not contribute significantly to the fishery. This could be related to the available habitat size but also associated with a resident type life history and increased cost of migration. The studies in my thesis highlight the importance of dense sampling and wide population coverage at the scale being studied and also demonstrate the importance of critical evaluation of the underlying assumptions of the population genetic models and methods used. These results have important implications for conservation and sustainable fisheries management of Finnish populations of European grayling and brown trout in the Inari basin.

Testaustapausten valitseminen on testauksessa tärkeää, koska kaikkia testaustapauksia ei voida testata aika- ja raharajoitteiden takia. Testaustapausten valintaan on paljon eri menetelmiä joista eniten esillä olevat ovat malleihin perustuva valinta, kombinaatiovalinta ja riskeihin perustuva valinta. Kaikkiin edellä mainittuihin menetelmiin testaustapaukset luodaan ohjelman spesifikaation perusteella. Malleihin perustuvassa menetelmässä käytetään hyväksi ohjelman toiminnasta olevia malleja, joista valitaan tärkeimmät testattavaksi. Kombinaatiotestauksessa testitapaukset on muodostettu ominaisuuspareina jolloin yhden parin testaamisesta päätellään kahden ominaisuuden toiminta. Kombinaatiotestaus on tehokas löytämään virheitä, jotka johtuvat yhdestä tai kahdesta tekijästä. Riskeihin perustuva testaus pyrkii arvioimaan ohjelman riskejä ja valitsemaan testitapaukset niiden perusteella. Kaikissa menetelmissä priorisointi on tärkeässä roolissa, jotta testauksesta saadaan riittävä luotettavuus ilman kustannusten nousua.

The objective of this thesis is to define supply management capability. The thesis study what factors consist of supply management capability, and which of those factors are critical to achieving competitive advantage. One objective is also to study how firms can measure their supply management capability. This study is a qualitative research. The thesis examines the literature regarding to supply management and the context of capability and there are used Delphi panel to examine the current and future insights of supply management professionals concerning of supply management skills and capability. The empirical data of the thesis was collected by interviews. The Delphi panel was used in data collection and analysis and for prioritization of the factors of supply management capability. The thesis includes lists of factors of supply management capability. Main findings of the study were that there is no one clear, generally suitable set of supply management skills which bring competitive advantage for all firms and the most important factors of supply management capability, according to the experts, are total cost analysis, customer focus, general business view, market knowledge and supplier relationships. In this study the supply management capability is defined as organization’s overall capacity and ability to achieve a holistic understanding of purchasing needs, manage its suppliers and collaborative partners, and conduct its internal tasks, routines and responsibilities in a way that achieves desired results. The results of this thesis show also that Finnish firms need more right kind of supply management knowledge.

CHARGE syndrome, Sotos syndrome and 3p deletion syndrome are examples of rare inherited syndromes that have been recognized for decades but for which the molecular diagnostics only have been made possible by recent advances in genomic research. Despite these advances, development of diagnostic tests for rare syndromes has been hindered by diagnostic laboratories having limited funds for test development, and their prioritization of tests for which a (relatively) high demand can be expected. In this study, the molecular diagnostic tests for CHARGE syndrome and Sotos syndrome were developed, resulting in their successful translation into routine diagnostic testing in the laboratory of Medical Genetics (UTUlab). In the CHARGE syndrome group, mutation was identified in 40.5% of the patients and in the Sotos syndrome group, in 34%, reflecting the use of the tests in routine diagnostics in differential diagnostics. In CHARGE syndrome, the low prevalence of structural aberrations was also confirmed. In 3p deletion syndrome, it was shown that small terminal deletions are not causative for the syndrome, and that testing with arraybased analysis provides a reliable estimate of the deletion size but benign copy number variants complicate result interpretation. During the development of the tests, it was discovered that finding an optimal molecular diagnostic strategy for a given syndrome is always a compromise between the sensitivity, specificity and feasibility of applying a new method. In addition, the clinical utility of the test should be considered prior to test development: sometimes a test performing well in a laboratory has limited utility for the patient, whereas a test performing poorly in the laboratory may have a great impact on the patient and their family. At present, the development of next generation sequencing methods is changing the concept of molecular diagnostics of rare diseases from single tests towards whole-genome analysis.

Työn tarkoituksena on tutkia, mitkä ovat tärkeimpiä tekijöitä, joita Balanced Scorecard johtamisjärjestelmää käyttävän organisaatioiden tulee huomioida innovaatioprosessinsa suunnittelussa ja toteutuksessa. Lisäksi työssä tutkitaan, millaisia kytkentöjä innovaatioprosessilla on BSC-johtamisjärjestelmän muihin osa-alueisiin sekä onko BSC ylipäätään sopiva johtamisjärjestelmä innovatiivisuutta tavoittelevalla organisaatiolle. Tutkimusstrategiana on kvalitatiivinen tutkimus ja tutkimusmetodina puolestaan puolistrukturoimaton haastattelu. Työn tärkein tutkimustulos on, että BSC-johtamisjärjestelmää käyttävän organisaation innovaatioprosessin onnistuminen ratkaistaan pitkälti aivan muualla kuin prosessin sisällä itsessään. Organisaation tulee ensinnäkin keskittyä edistämään innovaatioille suotuisaa kulttuuria, tässä organisaation arvot ovat yksi tärkein työväline. Toiseksi, organisaation tulee systemaattisesti kehittää yhteistyötä eri funktioiden ja niissä työskentelevien ihmisten välillä. Kolmanneksi, organisaation tulee mitata systemaattisesti niitä asioita, jotka indikoivat innovaatioiden edellytyksistä ja itse innovaatioprosessin toimivuudesta. Kaikki kolme mainittua tulosta liitetään työssä kirjoittajan toimesta yläkäsitteen johtaminen alle. Työssä tuodaan myös esille se, että organisaatioiden on syytä tarkastella edellä mainittuja kolmea teemaa kahdessa aikaulottuvuudessa – ajassa ennen innovaatioita ja varsinaisen innovaation jälkeen. Siten kunkin kolmen teeman olennaisin sisältö riippuukin aikaperspektiivistä. Yhtenä olennaisena johtopäätöksenä työn tekijä esittää, että BSC-johtamisjärjestelmää käyttävän organisaation ei tulisi investoida merkittävästi varsinaiseen innovaatioprosessiinsa ennen kuin se on kyennyt luomaan innovatiivisuutta tukevaa kulttuuria oppimisen ja kasvun näkökulmassa. Ilman innovaatioita tukevaa kulttuuria prosessissa itsessään tuskin on laadukasta sisältöä. Tämä johtopäätös on selkeä viesti organisaatioille toiminnan priorisoinnin kannalta.
