SC-paperirullien vanaisuuden syntymekanismien selvittäminen

Myllykoski Paper Oy:n PK6:n kapeiden asiakasrullien vanoittuminen on aiheuttanut tuotannonmenetyksiä. Tämän työn tavoitteena oli pyrkiä selvittämään SC-paperirullissa esiintyvän vanaisuuden syntymekanismeja ja sitä, kuinka pituusleikkurilla voitaisiin vähentää vanan muodostumista asiakasrulliin. Työn kirjallisuusosassa selvitettiin rullaustapahtumaa pituusleikkurilla, paperin rullautuvuuteen vaikuttavia tekijöitä ja SC-paperille soveltuvia pituusleikkurityyppejä. Tässäyhteydessä syvennyttiin vanan syntymekanismeihin ja vanan syntymisen mahdollisiin ehkäisymenetelmiin. Vanan muodostumiseen vaikuttavat rainassa olevat jyrkät muutokset mm. neliömassa- ja paksuuspoikkiprofiileissa sekä pituusleikkurin rullausasemien linjauksen virheellisyys. Työn kokeellinen osa jakautui kahteen osaan.Esikokeissa tilastoitiin vanarullien muodostuminen eri pituusleikkurin rullausasemien, rullausposition ja käytetyn superkalanterin mukaan. Vanarullien paperista tutkittiin poikkisuuntaisia profiileja vanan syntysyiden löytämiseksi. Vanarullat olivat pääasiassa rainan reunoista leikattuja ja esikokeiden aikana suurin osan vanarullista muodostui superkalanteri II:n tambuureista. Koeajossa tutkittiin pituusleikkurin ajoparametrien ja rullausposition vaikutusta vanan muodostumiseen kapeassa rainan reunaosasta leikattavassa rullassa. Paperissa olevan profiilivian aiheuttamaa vanaa ei pystytty poistamaan ajoparametrimuutoksilla poistamaan koeajossa. Pituusleikkurin rullausasemien ja telojen linjaus sekä liikkuvien osien välysten poistaminen vähensi vanan muodostumista. Paperin neliömassa- ja paksuusprofiileissa kapealla alueella tapahtuvat jyrkät muutokset lisäsivät merkittävästi vanan muodostumista. Paperin profiilien hallinnalla ja pituusleikkurin kuluvien osien ennakoivalla huollolla voidaan vähentää vanan muodostumista asiakasrulliin.

Forensic intelligence framework-Part I: induction of a transversal model by comparing illicit drugs and false identity documents monitoring

Forensic intelligence is a distinct dimension of forensic science. Forensic intelligence processes have mostly been developed to address either a specific type of trace or a specific problem. Even though these empirical developments have led to successes, they are trace-specific in nature and contribute to the generation of silos which hamper the establishment of a more general and transversal model. Forensic intelligence has shown some important perspectives but more general developments are required to address persistent challenges. This will ensure the progress of the discipline as well as its widespread implementation in the future. This paper demonstrates that the description of forensic intelligence processes, their architectures, and the methods for building them can, at a certain level, be abstracted from the type of traces considered. A comparative analysis is made between two forensic intelligence approaches developed independently in Australia and in Europe regarding the monitoring of apparently very different kind of problems: illicit drugs and false identity documents. An inductive effort is pursued to identify similarities and to outline a general model. Besides breaking barriers between apparently separate fields of study in forensic science and intelligence, this transversal model would assist in defining forensic intelligence, its role and place in policing, and in identifying its contributions and limitations. The model will facilitate the paradigm shift from the current case-by-case reactive attitude towards a proactive approach by serving as a guideline for the use of forensic case data in an intelligence-led perspective. A follow-up article will specifically address issues related to comparison processes, decision points and organisational issues regarding forensic intelligence (part II).

Yrittäjämäisen markkinoinnin käsitteelliset elementit

Tällä hetkellä markkinoinnin yksi tuoreimmista tutkimusalueista on yrittäjämäinen markkinointi. Yrittäjämäinen markkinointi on suomennos englanninkielisistä sanoista entrepreneurial marketing. Yrittäjämäinen markkinointi yhdistää markkinoinnin ja yrittäjyyden. Yrittäjämäisellä markkinoinnilla tarkoitetaan yksilön tai organisaation käyttäytymistä tavalla, joka haastaa markkinoiden tavanomaiset toimintamallit. Se on proaktiivinen, innovatiivinen ja riskejä ottava markkinointimalli, joka tunnistaa ja hyödyntää mahdollisuuksia markkinoilla houkutellakseen asiakkaita ja luodakseen kannattavia asiakassuhteita. Vaikka tai ehkä juuri siksi, että yrittäjämäinen markkinointi eroaa markkinoinnin oppikirjoissa esitetyistä perinteisistä teorioista, tutkimukset ovat osoittaneet, että yritykset ovat onnistuneet luomaan menestyvää liiketoimintaa toimimalla yrittäjämäisesti. Tämän pro gradu -tutkielman tarkoituksena on tarkastella yrittäjämäisen markkinoinnin käsitettä. Tutkielma on teoreettinen, käsiteanalyyttinen työ. Tutkielmassa lähdetään liikkeelle tarkastelemalla markkinoinnin ja yrittäjyyden käsitteitä sekä näiden käsitteiden muodostamaa rajapintaa. Markkinoinnin uudelleen käsitteellistäminen, jossa yrittäjämäisessä markkinoinnissakin on kysymys, vaatii kuitenkin myös markkinoinnin ymmärtämistä kolmella tasolla ¿ kulttuurina,strategiana ja taktiikkana. Yrittäjämäinen markkinointi tarjoaa viitekehyksen markkinoinnin uusille vaatimuksille tulevaisuudessa vastauksena perinteiseen markkinointiin kohdistuneeseen kritiikkiin.

Valoración experiencial del aprendizaje tras formación virtual.

[eng] An observable study on the behaviour in the laboratory of Pharmaceutical Technology II (pharmaceutical pilot plant), with two groups of students of 3rd course (proactive aptitude and valuation of the"knowledge to do acquired") is carried out. The variable between groups is that one has realised a training (by means of self-study of an interactive application multimedia, especially designed), without tutorship on behalf the teacher in front of the other group that carried out the same training with the same material but with the guide of the teacher in the computer lab. On the one hand it is valued if there is some effect differentiator between both types of training, by means of the accounting of the correct results obtained in a previous test to the entrance in the pilot plant and by another one the valuation that the professors made responsible for the groups of practices in situ. The results demonstrate the previous hypothesis that there must not be significant differences between the groups, beyond the inherent ones to personality of the students itself (interest and personal implication by the subject). On the other hand the test for the observation in the laboratory did not facilitate the distinction of objective differences. [spa] Se lleva a cabo un estudio observacional sobre el comportamiento de los estudiantes (aptitud pro-activa y valoración del “saber hacer adquirido”) en el laboratorio de Tecnología Farmacéutica II (planta piloto farmacéutica) de dos grupos de estudiantes de 3er curso. La variable entre los dos grupos es que uno ha realizado una formación no presencial (mediante el autoestudio de una aplicación interactiva multimedia, especialmente diseñada), sin tutoría por parte del profesor, frente al otro grupo que llevó a cabo la misma formación con el mismo material pero con la guía del profesor en el aula de informática. Por una parte se valora si hay algún efecto diferenciador entre ambos tipos de formación, mediante la contabilización de los resultados correctos obtenidos en un test previo a la entrada en la planta piloto y por otro la valoración que hicieron los profesores responsables de los grupos de prácticas in situ. Los resultados demuestran la hipótesis previa de que no debían existir diferencias significativas entre los grupos, más allá de las inherentes a la propia personalidad de los estudiantes (interés e implicación personal por el tema). Por otra parte el test para la observación en el laboratorio no facilitó la distinción de diferencias objetivas.

Competitive intelligence yksikön palvelustrategia

Tutkimuksen tavoitteena oli selvittää, kuinka yrityksen Compeitive Intelligence (CI) yksikön palvelustrategia pitäisi rakentaa ja mitä tekijöitä ottaa huomioon palvelustrategian rakentamisessa, jotta se parhaiten tukisi CI-yksikön integrointia muuhun organisaatioon. Tutkimus suoritettiin laadullisena case tutkimuksena. Tutkimuksen aineisto kerättiin kirjallisuudesta, artikkeleista sekä suorittamalla teemahaastatteluja. Tutkimuksen teoreettisena pohjana käytettiin näkemyksiä markkina-, kilpailu- ja liiketoimintatiedosta, palveluiden markkinoinnista sekä tietojohtamisesta. Tutkimuksen empiirinen aineisto kerättiin haastattelemalla kymmenen CI-yksikön asiakasta kohdeyrityksestä. Niin teorialähteiden kuin kohdeyrityksessä kerätyn materiaalin pohjalta voidaan sanoa, että palvelustrategiaa suunniteltaessa oleellisia elementtejä, joilla voidaan parantaa CI:n integrointia muuhun organisaatioon, ovat palvelu/tuote, jakelu sekä viestintä ja vuorovaikutus. Palvelustrategian rakentamisessa erityisessä ja keskeisessä asemassa on vuorovaikutus. Vuorovaikutuksen merkitys korostuu, koska sillä on vaikutusta palvelustrategian muihin elementteihin, kuten tiedon laatuun ja proaktiiviseen tiedon jakeluun.

Empiirisen osuuden muodostaa kvantitatiivinen tutkimus, joka suoritettiin kirjekyselynä. Tutkimuksen perusteella päädyttiin seuraaviin tuloksiin ja suosituksiin: Myyntityön tulisi olla aktiivisempaa. Markkinoinnissa on hyväkorostaa suhteelliseen hyötyyn lukeutuvia ominaisuuksia. Referenssien käyttöä tulisi tehostaa. Havaittiin myös, että nykyiset asiakkaat ovat olleet erittäin tyytyväisiä ohjelmistoon.

Onnistuneen uuden tuotteen kehittäminen ja hallinta - Tapaustutkimus: Tekstiilialan yritys

Tuotesuunnittelu on yrityksen selviämisen kannalta erittäin tärkeä toiminto. Menestynyt tuotesuunnittelu vaatii selkeän tuotestrategian, laadukkaasti suoritetun tuotesuunnitteluprosessin ja tarvittavienresurssien yhdistämistä sekä uuden tuotteen tuottojen hallintaa myynnin seurannalla. Kohdeyrityksessä uusien tuotteiden suunnittelun ja hallinnan tärkeys on huomattu ja niiden kehittämiseksi yritys on lisäämässä panostustaan. Tämä tutkimuspyrkii tuomaan kohdeyrityksen tietoon tuotesuunnitteluun ja uuden tuotteen hallintaan vaikuttavat menestystekijät sekä tuomaan esille näitä toimintoja tukevia kehittämismahdollisuuksia. Tutkimus on normatiivinen tapaustutkimus, jossa teoria on koottu tieteellisistä, lähinnä empiirisistä tutkimuksista koostuvista artikkeleista. Yrityksen tuotesuunnitteluun liittyvät prosessit ja toiminnot on selvitetty puolistrukturoiduilla haastatteluilla sekä havainnoimalla. Tutkimuksessa havaittiin selkeitä eroja uuden tuotteen hallinnan menestystekijöiden ja yrityksen toimintojen välillä. Tuotesuunnitteluprosessin uudelleen organisointi, toimitusketjun hallinta ja tuotekohtainen kustannuslaskenta ovat asioita, joita kehittämällä yritys voi mahdollisesti parantaa uusien tuotteiden elinkaaren aikaista hallintaa ja taloudellista onnistumista sekä lisätä yrityksen kannattavuutta.

Supporting knowledge creation and sharing in the early phases of the strategic innovation process

The driving forces of technology and globalization continuously transform the business landscape in a way which undermines the existing strategies and innovations of organizations. The challenge for organizations is to establish such conditions where they are able to create new knowledge for innovative business ideas in interaction between other organizations and individuals. Innovation processes continuously need new external stimulations and seek new ideas, new information and knowledge locating more and more outside traditional organizational boundaries. In several studies, the early phases of the innovation process have been considered as the most critical ones. During these phases, the innovation process can emerge or conclude. External knowledge acquirement and utilization are noticed to be important at this stage of the innovation process giving information about the development of future markets and needs for new innovative businessideas. To make it possible, new methods and approaches to manage proactive knowledge creation and sharing activities are needed. In this study, knowledge creation and sharing in the early phases of the innovation process has been studied, and the understanding of knowledge management in the innovation process in an open and collaborative context advanced. Furthermore, the innovation management methods in this study are combined in a novel way to establish an open innovation process and tested in real-life cases. For these purposes two complementary and sequentially applied group work methods - the heuristic scenario method and the idea generation process - are examined by focusing the research on the support of the open knowledge creation and sharing process. The research objective of this thesis concerns two doctrines: the innovation management including the knowledge management, and the futures research concerning the scenario paradigm. This thesis also applies the group decision support system (GDSS) in the idea generation process to utilize the converged knowledge during the scenario process.

Exploration of the social dimension of corporate responsibility in a welfare state

This study focuses on corporate social responsibility (or CSR)as the latest dimension to emerge in the corporate responsibility and sustainability agenda, which in the recent past has rapidly risen to the top of the list of concerns for civil societies worldwide. Despite the continuing debates and discussions about the scope, benefits, and impacts of CSR to business and community in various sectors, levels, and types of society, many companies have moved forward to confront the opportunities and challenges of CSR. Thus, this study is about those proactive companies with a focus on the importance of CSR and its management inside and outside the company. It is an exploration and learning from the experience of Finnish companies, as well as other actors interested or involved in shaping the course of CSR, locally and globally. It also looks closely at how national culture affects the views, thinking, and management of CSR in a welfare state. This dissertation primarily draws on the analyses of information collected from a series of qualitative interviews and the existing literature in the area. This is complemented by an analysis of written and published documents on CSR from various sources. The results of the study give insightful information and detailed descriptions of a roadmap useful in learning and understanding CSR in Finnish companies. Despite the varying conceptual connotations, essential roadmap indicators point to the importance of framing CSR within the corporate responsibility concept, Finnish development and the welfare state system, globalization, stakeholders, and the pursuit of sustainable development as the main drivers of CSR, the remarkable progress of CSR in companies, and identification of key management areas and practices relevant to CSR. Similarly,the study reveals the importance of culture as essential in understanding and learning CSR. Finnish culture has a positive influence on the views, thinking, and management practices of CSR issues. Such a positive influence of culture, therefore, makes it easy for business people to discuss and understand CSR, because those CSR issues are already considered common and taken-for-granted by Finns and are implicit in the welfare state provisions. The experience of Finnish companies in implementing CSR policies in the supply chain is a concrete proactive step in advancing the message of CSR, that is, to bring companies and suppliers together to work on improving and strengthening relationships towards socially responsible practices worldwide. Such a forward step to deal with CSR issues in the supply chain reflects the companies' commitments and belief that CSR can be managed with the suppliers and gain positive benefits. Despite the problems and complexities, particularly in the global supply chain, managing CSR for Finnish companies presents new opportunities and challenges that are expected to intensify in the near future. The focus on CSR policy implementation inthe supply chain points to the importance of companies taking initiatives and forging cooperation with suppliers with the aim of addressing and improving CSR questions in the supply chains. The proactive stance of Finnish companies toward CSR is complemented by the active supporting role of important societalactors such as the government and NGOs. These actors carry out various promotional efforts and campaigns, thus bringing CSR into the mainstream of Finnish companies and strengthening the synergistic learning about CSR within the Finnish business and civil circles. The efforts of the government and NGOs to promote CSR are indicative of the importance of multipartite involvement and the emergence of better civil regulations. Likewise, their drive to learn from each other, exchange experiences, and contribute in CSR debates facilitated the evolution of CSRnetworks in the country. The results of this study add to the mounting evidence that CSR, in general, has created a new dimension in managing corporate sustainability. This study provides compelling empirical evidence and some direct quotations about CSR in the Finnish context. This information can be used to learn and gain new useful insights, approaches, and concepts for managing CSR.

Dynamic Capabilities and Firm Performance

Firms operating in a changing environment have a need for structures and practices that provide flexibility and enable rapid response to changes. Given the challenges they face in attempts to keep up with market needs, they have to continuously improve their processes and products, and develop new products to match market requirements. Success in changing markets depends on the firm's ability to convert knowledge into innovations, and consequently their internal structures and capabilities have an important role in innovation activities. According 10 the dynamic capability view of the firm, firms thus need dynamic capabilities in (he form ofassets, processes and structures that enable strategic flexibility and support entrepreneurial opportunity sensing and exploitation. Dynamic capabilities are also needed in conditions of rapid change in the operating environment, and in activities such as new product development and expansion to new markets. Despite the growing interest in these issues and the theoretical developments in the field of strategy research, there are still only very few empirical studies, and large-scale empirical studies in particular, that provide evidence that firms'dynamic capabilities are reflected in performance differences. This thesis represents an attempt to advance the research by providing empirical evidence of thelinkages between the firm's dynamic capabilities and performance in intenationalization and innovation activities. The aim is thus to increase knowledge and enhance understanding of the organizational factors that explain interfirm performance differences. The study is in two parts. The first part is the introduction and the second part comprises five research publications covering the theoretical foundations of the dynamic capability view and subsequent empirical analyses. Quantitative research methodology is used throughout. The thesis contributes to the literature in several ways. While a lot of prior research on dynamic capabilities is conceptual in nature, or conducted through case studies, this thesis introduces empirical measures for assessing the different aspects, and uses large-scale sampling to investigate the relationships between them and performance indicators. The dynamic capability view is further developed by integrating theoretical frameworks and research traditions from several disciplines. The results of the study provide support for the basic tenets of the dynamic capability view. The empirical findings demonstrate that the firm's ability to renew its knowledge base and other intangible assets, its proactive, entrepreneurial behavior, and the structures and practices that support operational flexibility arepositively related to performance indicators.

Project Success through Effective Decisions: Case Studies on Project Goal Setting, Success Evaluation and Managerial Decision Making

The objective of the thesis is to structure and model the factors that contribute to and can be used in evaluating project success. The purpose of this thesis is to enhance the understanding of three research topics. The goal setting process, success evaluation and decision-making process are studied in the context of a project, business unitand its business environment. To achieve the objective three research questionsare posed. These are 1) how to set measurable project goals, 2) how to evaluateproject success and 3) how to affect project success with managerial decisions.The main theoretical contribution comes from deriving a synthesis of these research topics which have mostly been discussed apart from each other in prior research. The research strategy of the study has features from at least the constructive, nomothetical, and decision-oriented research approaches. This strategy guides the theoretical and empirical part of the study. Relevant concepts and a framework are composed on the basis of the prior research contributions within the problem area. A literature review is used to derive constructs of factors withinthe framework. They are related to project goal setting, success evaluation, and decision making. On the basis of this, the case study method is applied to complement the framework. The empirical data includes one product development program, three construction projects, as well as one organization development, hardware/software, and marketing project in their contexts. In two of the case studiesthe analytic hierarchy process is used to formulate a hierarchical model that returns a numerical evaluation of the degree of project success. It has its origin in the solution idea which in turn has its foundation in the notion of projectsuccess. The achieved results are condensed in the form of a process model thatintegrates project goal setting, success evaluation and decision making. The process of project goal setting is analysed as a part of an open system that includes a project, the business unit and its competitive environment. Four main constructs of factors are suggested. First, the project characteristics and requirements are clarified. The second and the third construct comprise the components of client/market segment attractiveness and sources of competitive advantage. Together they determine the competitive position of a business unit. Fourth, the relevant goals and the situation of a business unit are clarified to stress their contribution to the project goals. Empirical evidence is gained on the exploitation of increased knowledge and on the reaction to changes in the business environment during a project to ensure project success. The relevance of a successful project to a company or a business unit tends to increase the higher the reference level of project goals is set. However, normal performance or sometimes performance below this normal level is intentionally accepted. Success measures make project success quantifiable. There are result-oriented, process-oriented and resource-oriented success measures. The study also links result measurements to enablers that portray the key processes. The success measures can be classified into success domains determining the areas on which success is assessed. Empiricalevidence is gained on six success domains: strategy, project implementation, product, stakeholder relationships, learning situation and company functions. However, some project goals, like safety, can be assessed using success measures that belong to two success domains. For example a safety index is used for assessing occupational safety during a project, which is related to project implementation. Product safety requirements, in turn, are connected to the product characteristics and thus to the product-related success domain. Strategic success measures can be used to weave the project phases together. Empirical evidence on their static nature is gained. In order-oriented projects the project phases are oftencontractually divided into different suppliers or contractors. A project from the supplier's perspective can represent only a part of the ¿whole project¿ viewed from the client's perspective. Therefore static success measures are mostly used within the contractually agreed project scope and duration. Proof is also acquired on the dynamic use of operational success measures. They help to focus on the key issues during each project phase. Furthermore, it is shown that the original success domains and success measures, their weights and target values can change dynamically. New success measures can replace the old ones to correspond better with the emphasis of the particular project phase. This adjustment concentrates on the key decision milestones. As a conclusion, the study suggests a combination of static and dynamic success measures. Their linkage to an incentive system can make the project management proactive, enable fast feedback and enhancethe motivation of the personnel. It is argued that the sequence of effective decisions is closely linked to the dynamic control of project success. According to the used definition, effective decisions aim at adequate decision quality and decision implementation. The findings support that project managers construct and use a chain of key decision milestones to evaluate and affect success during aproject. These milestones can be seen as a part of the business processes. Different managers prioritise the key decision milestones to a varying degree. Divergent managerial perspectives, power, responsibilities and involvement during a project offer some explanation for this. Finally, the study introduces the use ofHard Gate and Soft Gate decision milestones. The managers may use the former milestones to provide decision support on result measurements and ad hoc critical conditions. In the latter milestones they may make intermediate success evaluation also on the basis of other types of success measures, like process and resource measures.

Personality and job stress: a comparison of direct effects on parenting

The impact of personality and job characteristics on parental rearing styles was compared in 353 employees. Hypotheses concerning the relationships between personality and job variables were formulated in accordance with findings in past research and the Belsky’s model (1984). Structural equation nested models showed that Aggression-hostility, Sociability and job Demand were predictive of Rejection and Emotional Warmth parenting styles, providing support for some of the hypothesized relationships. The findings suggest a well-balanced association of personality variables with both parenting styles: Aggression-Hostility was positively related to Rejection and negatively to Emotional Warmth, whereas Sociability was positively related to Emotional Warmth and negatively related to Rejection. Personality dimensions explained a higher amount of variance in observed parenting styles. However, a model that considered both, personality and job dimensions as antecedent variables of parenting was the best representation of observed data, as both systems play a role in the prediction of parenting behavior.

Des faux documents d'identité au renseignement forensique : développement d'une approche systématique et transversale du traitement de la donnée forensique à des fins de renseignement criminel

La fabrication, la distribution et l'usage de fausses pièces d'identité constituent une menace pour la sécurité autant publique que privée. Ces faux documents représentent en effet un catalyseur pour une multitude de formes de criminalité, des plus anodines aux formes les plus graves et organisées. La dimension, la complexité, la faible visibilité, ainsi que les caractères répétitif et évolutif de la fraude aux documents d'identité appellent des réponses nouvelles qui vont au-delà d'une approche traditionnelle au cas par cas ou de la stratégie du tout technologique dont la perspective historique révèle l'échec. Ces nouvelles réponses passent par un renforcement de la capacité de comprendre les problèmes criminels que posent la fraude aux documents d'identité et les phénomènes qui l'animent. Cette compréhension est tout bonnement nécessaire pour permettre d'imaginer, d'évaluer et de décider les solutions et mesures les plus appropriées. Elle requière de développer les capacités d'analyse et la fonction de renseignement criminel qui fondent en particulier les modèles d'action de sécurité les plus récents, tels que l'intelligence-led policing ou le problem-oriented policing par exemple. Dans ce contexte, le travail doctoral adopte une position originale en postulant que les fausses pièces d'identité se conçoivent utilement comme la trace matérielle ou le vestige résultant de l'activité de fabrication ou d'altération d'un document d'identité menée par les faussaires. Sur la base de ce postulat fondamental, il est avancé que l'exploitation scientifique, méthodique et systématique de ces traces au travers d'un processus de renseignement forensique permet de générer des connaissances phénoménologiques sur les formes de criminalité qui fabriquent, diffusent ou utilisent les fausses pièces d'identité, connaissances qui s'intègrent et se mettent avantageusement au service du renseignement criminel. A l'appui de l'épreuve de cette thèse de départ et de l'étude plus générale du renseignement forensique, le travail doctoral propose des définitions et des modèles. Il décrit des nouvelles méthodes de profilage et initie la constitution d'un catalogue de formes d'analyses. Il recourt également à des expérimentations et des études de cas. Les résultats obtenus démontrent que le traitement systématique de la donnée forensique apporte une contribution utile et pertinente pour le renseignement criminel stratégique, opérationnel et tactique, ou encore la criminologie. Combiné aux informations disponibles par ailleurs, le renseignement forensique produit est susceptible de soutenir l'action de sécurité dans ses dimensions répressive, proactive, préventive et de contrôle. En particulier, les méthodes de profilage des fausses pièces d'identité proposées permettent de révéler des tendances au travers de jeux de données étendus, d'analyser des modus operandi ou d'inférer une communauté ou différence de source. Ces méthodes appuient des moyens de détection et de suivi des séries, des problèmes et des phénomènes criminels qui s'intègrent dans le cadre de la veille opérationnelle. Ils permettent de regrouper par problèmes les cas isolés, de mettre en évidence les formes organisées de criminalité qui méritent le plus d'attention, ou de produire des connaissances robustes et inédites qui offrent une perception plus profonde de la criminalité. Le travail discute également les difficultés associées à la gestion de données et d'informations propres à différents niveaux de généralité, ou les difficultés relatives à l'implémentation du processus de renseignement forensique dans la pratique. Ce travail doctoral porte en premier lieu sur les fausses pièces d'identité et leur traitement par les protagonistes de l'action de sécurité. Au travers d'une démarche inductive, il procède également à une généralisation qui souligne que les observations ci-dessus ne valent pas uniquement pour le traitement systématique des fausses pièces d'identité, mais pour celui de tout type de trace dès lors qu'un profil en est extrait. Il ressort de ces travaux une définition et une compréhension plus transversales de la notion et de la fonction de renseignement forensique. The production, distribution and use of false identity documents constitute a threat to both public and private security. Fraudulent documents are a catalyser for a multitude of crimes, from the most trivial to the most serious and organised forms. The dimension, complexity, low visibility as well as the repetitive and evolving character of the production and use of false identity documents call for new solutions that go beyond the traditional case-by-case approach, or the technology-focused strategy whose failure is revealed by the historic perspective. These new solutions require to strengthen the ability to understand crime phenomena and crime problems posed by false identity documents. Such an understanding is pivotal in order to be able to imagine, evaluate and decide on the most appropriate measures and responses. Therefore, analysis capacities and crime intelligence functions, which found the most recent policing models such as intelligence-led policing or problem-oriented policing for instance, have to be developed. In this context, the doctoral research work adopts an original position by postulating that false identity documents can be usefully perceived as the material remnant resulting from the criminal activity undertook by forgers, namely the manufacture or the modification of identity documents. Based on this fundamental postulate, it is proposed that a scientific, methodical and systematic processing of these traces through a forensic intelligence approach can generate phenomenological knowledge on the forms of crime that produce, distribute and use false identity documents. Such knowledge should integrate and serve advantageously crime intelligence efforts. In support of this original thesis and of a more general study of forensic intelligence, the doctoral work proposes definitions and models. It describes new profiling methods and initiates the construction of a catalogue of analysis forms. It also leverages experimentations and case studies. Results demonstrate that the systematic processing of forensic data usefully and relevantly contributes to strategic, tactical and operational crime intelligence, and also to criminology. Combined with alternative information available, forensic intelligence may support policing in its repressive, proactive, preventive and control activities. In particular, the proposed profiling methods enable to reveal trends among extended datasets, to analyse modus operandi, or to infer that false identity documents have a common or different source. These methods support the detection and follow-up of crime series, crime problems and phenomena and therefore contribute to crime monitoring efforts. They enable to link and regroup by problems cases that were previously viewed as isolated, to highlight organised forms of crime which deserve greatest attention, and to elicit robust and novel knowledge offering a deeper perception of crime. The doctoral research work discusses also difficulties associated with the management of data and information relating to different levels of generality, or difficulties associated with the implementation in practice of the forensic intelligence process. The doctoral work focuses primarily on false identity documents and their treatment by policing stakeholders. However, through an inductive process, it makes a generalisation which underlines that observations do not only apply to false identity documents but to any kind of trace as soon as a profile is extracted. A more transversal definition and understanding of the concept and function of forensic intelligence therefore derives from the doctoral work.

Nosturivaihteiden kunnonvalvontajärjestelmän kehittäminen värähtelymittauksia käyttäen

Työssä selvitettiin värähtelymittauksien käyttömahdollisuuksia nosturivaihteiden ennakoivassa kunnonvalvonnassa. Työ on painottunut lähinnä värähtelymittausten mittaus- ja analyysiteknisten näkökohtien tarkasteluun ja toimii niiltä osin al-kuselvityksenä värähtelymittauspohjaisen kunnonvalvontajärjestelmän luomiselle. Kirjallisuuden mukaan yleisimpiä ja käyttökelpoisimpia värähtelyanalyysejä vaihteistojen kunnonvalvonnassa ovat spektri-, kepstri-, ja demodulointitekniik-kaan perustuvat analyysit, joita kokeiltiin vauriokokeilla. Työssä käsitellään myös iskusysäysmenetelmää ja aikatason tunnuslukuja. Vauriokokeilla saatiin tietoa hammasvaurioiden havaitsemisesta värähtelymittauksilla, mutta laakerivaurioista kaivataan sen sijaan vielä lisää tietoa. Hammasvaurioiden tarkastelussa spektri-analyysin ohella PeakVue -analyysi osoittautui tehokkaaksi, kun siinä käytettiin sopivaa suodatusaluetta. Lisäksi työhön on koottu kokemuksia nosturivaihteiden käytännön värähtelymittauksista ja annettu ohjeita niiden suorittamisesta. Työn tulokset osoittavat, että värähtelymittauspohjaisella kunnonvalvontajärjes-telmällä voidaan parantaa nostovaihteiden ennakoivaa kunnonvalvontaa. Nosto-vaihteiden värähtelymittauksia kannattaa siis ehdottomasti jatkaa ja kunnonval-vontajärjestelmää edelleen kehittää. Siirtovaihteiden valvonta värähtelymittauksilla on sen sijaan hankalaa niiden epävakaan kuormitustilan vuoksi.
