Cancer genes hypermethylated in human embryonic stem cells.

Developmental genes are silenced in embryonic stem cells by a bivalent histone-based chromatin mark. It has been proposed that this mark also confers a predisposition to aberrant DNA promoter hypermethylation of tumor suppressor genes (TSGs) in cancer. We report here that silencing of a significant proportion of these TSGs in human embryonic and adult stem cells is associated with promoter DNA hypermethylation. Our results indicate a role for DNA methylation in the control of gene expression in human stem cells and suggest that, for genes repressed by promoter hypermethylation in stem cells in vivo, the aberrant process in cancer could be understood as a defect in establishing an unmethylated promoter during differentiation, rather than as an anomalous process of de novo hypermethylation.

Although it has long been known that genetic factors play a major role in shaping the electroencephalogram (EEG), progress on identifying the underlying genes has, until recently, been limited. Using quantitative trait loci (QTL) analyses several genomic loci affecting the sleep EEG could be mapped in the mouse. For three of these QTLs the responsible genes were identified leading to the implication of novel signaling pathways affecting EEG traits. Moreover, the insight that in the mouse the sleep-wake dependent dynamics in the expression of EEG slow waves during sleep is under strong genetic control has paved the way for candidate gene studies in humans investigating the contribution of specific polymorphism to the trait-like inter-individual differences in the susceptibility to sleep loss. Candidate gene studies in the mouse were also instrumental in establishing an alternative, noncircadian function for clock genes in the homeostatic regulation of sleep and modulating rhythmic EEG activity of thalamocortical origin. Future efforts should combine system genetics approaches in the mouse and genome-wide association studies in humans to facilitate uncovering the molecular pathways that shape brain activity.

Identification and modelling of human breast cancer subtypes

Résumé Le cancer du sein est le cancer le plus commun chez les femmes et est responsable de presque 30% de tous les nouveaux cas de cancer en Europe. On estime le nombre de décès liés au cancer du sein en Europe est à plus de 130.000 par an. Ces chiffres expliquent l'impact social considérable de cette maladie. Les objectifs de cette thèse étaient: (1) d'identifier les prédispositions et les mécanismes biologiques responsables de l'établissement des sous-types spécifiques de cancer du sein; (2) les valider dans un modèle ín vivo "humain-dans-souris"; et (3) de développer des traitements spécifiques à chaque sous-type de cancer du sein identifiés. Le premier objectif a été atteint par l'intermédiaire de l'analyse des données d'expression de gènes des tumeurs, produite dans notre laboratoire. Les données obtenues par puces à ADN ont été produites à partir de 49 biopsies des tumeurs du sein provenant des patientes participant dans l'essai clinique EORTC 10994/BIG00-01. Les données étaient très riches en information et m'ont permis de valider des données précédentes des autres études d'expression des gènes dans des tumeurs du sein. De plus, cette analyse m'a permis d'identifier un nouveau sous-type biologique de cancer du sein. Dans la première partie de la thèse, je décris I identification des tumeurs apocrines du sein par l'analyse des puces à ADN et les implications potentielles de cette découverte pour les applications cliniques. Le deuxième objectif a été atteint par l'établissement d'un modèle de cancer du sein humain, basé sur des cellules épithéliales mammaires humaines primaires (HMECs) dérivées de réductions mammaires. J'ai choisi d'adapter un système de culture des cellules en suspension basé sur des mammosphères précédemment décrit et pat décidé d'exprimer des gènes en utilisant des lentivirus. Dans la deuxième partie de ma thèse je décris l'établissement d'un système de culture cellulaire qui permet la transformation quantitative des HMECs. Par la suite, j'ai établi un modèle de xénogreffe dans les souris immunodéficientes NOD/SCID, qui permet de modéliser la maladie humaine chez la souris. Dans la troisième partie de ma thèse je décris et je discute les résultats que j'ai obtenus en établissant un modèle estrogène-dépendant de cancer du sein par transformation quantitative des HMECs avec des gènes définis, identifiés par analyse de données d'expression des gènes dans le cancer du sein. Les cellules transformées dans notre modèle étaient estrogène-dépendantes pour la croissance, diploïdes et génétiquement normales même après la culture cellulaire in vitro prolongée. Les cellules formaient des tumeurs dans notre modèle de xénogreffe et constituaient des métastases péritonéales disséminées et du foie. Afin d'atteindre le troisième objectif de ma thèse, j'ai défini et examiné des stratégies de traitement qui permettent réduire les tumeurs et les métastases. J'ai produit un modèle de cancer du sein génétiquement défini et positif pour le récepteur de l'estrogène qui permet de modéliser le cancer du sein estrogène-dépendant humain chez la souris. Ce modèle permet l'étude des mécanismes impliqués dans la formation des tumeurs et des métastases. Abstract Breast cancer is the most common cancer in women and accounts for nearly 30% of all new cancer cases in Europe. The number of deaths from breast cancer in Europe is estimated to be over 130,000 each year, implying the social impact of the disease. The goals of this thesis were first, to identify biological features and mechanisms --responsible for the establishment of specific breast cancer subtypes, second to validate them in a human-in-mouse in vivo model and third to develop specific treatments for identified breast cancer subtypes. The first objective was achieved via the analysis of tumour gene expression data produced in our lab. The microarray data were generated from 49 breast tumour biopsies that were collected from patients enrolled in the clinical trial EORTC 10994/BIG00-01. The data set was very rich in information and allowed me to validate data of previous breast cancer gene expression studies and to identify biological features of a novel breast cancer subtype. In the first part of the thesis I focus on the identification of molecular apacrine breast tumours by microarray analysis and the potential imptìcation of this finding for the clinics. The second objective was attained by the production of a human breast cancer model system based on primary human mammary epithelial cells {HMECs) derived from reduction mammoplasties. I have chosen to adopt a previously described suspension culture system based on mammospheres and expressed selected target genes using lentiviral expression constructs. In the second part of my thesis I mainly focus on the establishment of a cell culture system allowing for quantitative transformation of HMECs. I then established a xenograft model in immunodeficient NOD/SCID mice, allowing to model human disease in a mouse. In the third part of my thesis I describe and discuss the results that I obtained while establishing an oestrogen-dependent model of breast cancer by quantitative transformation of HMECs with defined genes identified after breast cancer gene expression data analysis. The transformed cells in our model are oestrogen-dependent for growth; remain diploid and genetically normal even after prolonged cell culture in vitro. The cells farm tumours and form disseminated peritoneal and liver metastases in our xenograft model. Along the lines of the third objective of my thesis I defined and tested treatment schemes allowing reducing tumours and metastases. I have generated a genetically defined model of oestrogen receptor alpha positive human breast cancer that allows to model human oestrogen-dependent breast cancer in a mouse and enables the study of mechanisms involved in tumorigenesis and metastasis.

O ensino e a prática da contabilidade, orientado para o desenvolvimento de competências científicas, tecnológicas e relacionais

A dissertação que ora apresentamos visa a obtenção do grau de mestre no MBA - Gestão de Empresas, pelo ISCTE Business School, Departamento de Gestão. Intitulado o ensino e prática da Contabilidade, orientado para o desenvolvimento de competências científicas, tecnológicas e relacionais, este estudo foi desenvolvido para tentarmos perceber até que ponto o ensino da contabilidade, no instituto eleito para o efeito, corresponde às expectativas da profissão, atendendo às competências que o mercado, inserido num mundo global em constantes mutações, determina como fundamentais para o sucesso da carreira contabilística. Com novas necessidades em competências, na prática contabilística, resultantes da utilização das TICs, presentes em qualquer ramo da esfera humana, tentámos perceber se o currículo do Curso de Contabilidade, do instituto, está projectado para conferir, aos diplomados, competências do saber-saber, saber-fazer, e saber-ser, em conformidade com tais necessidades ou, pelo contrário, baseia-se numa perspectiva tradicional assente numa pedagogia por objectivos, encontrando-se desactualizado. Tratou-se de um estudo de caso, numa investigação qualitativa holística, que permitiu desenvolver compreensões a partir das evidências reunidas, das representações dos sujeitos sobre quem recaem os resultados da investigação, que estabelecem uma relação indirecta com os mesmos resultados. Dos resultados obtidos, percebemos que o currículo do Curso de Contabilidade não se adequa a um currículo baseado em competências, sendo inadequado à realidade contabilística actual, local e global. As conclusões chegadas permitem-nos defender uma revisão curricular do curso para adequá-lo às competências necessárias à garantia duma profissão de contabilista de sucesso. Como contributo, propomos um plano de estudos alternativo. The present dissertation aims at obtaining the master degree in MBA - Management, ISCTE Business School, Department of Management. Titled the teaching and practice of accounting, aimed at developing scientific, technology and relations competencies, this study was designed trying to realize the extent to which accounting education, at the institute elected for that, has met the expectations of the profession given the skills that the market, housed in a global world in constant change, establishes as fundamental to successful accounting career. With new skills needs in accounting practice, resulting from the use of ICT, present in any branch of the human sphere, we tried to see if the accounting course curriculum, of the institute, is designed to give graduates the skills of knowing how to know, knowing how to do and how to be or, conversely, is based on a traditional perspective based on a pedagogy by objectives, and is outdated. It was a case study, a holistic qualitative research, which allowed us to develop insights from the evidence gathered, the representations of the subjects on whom fall the results of research, establishing an indirect link with the same results. From our results, we find that the accounting course curriculum is not appropriate for a curriculum based on skills, and unsuited to current accounting practice, locally and globally. The conclusions reached allow us to defend a curriculum review of the course to suit the skills necessary to ensure a successful accountancy profession. As a contribution, we propose an alternative curriculum.

The use of textbooks in Capeverdean secondary schools: The Relationship between Use, Evaluation and Adaptation of Textbooks

This study examines the relationship between teacher’s use of English textbooks and the way teachers evaluate and adapt them, looking at a particular context, the Capeverdean secondary schools, specifically in Praia. The referred relationship was analyzed through teachers’ responses about how they use, evaluate and adapt their textbooks. The results of the study revealed that, on the one hand, the way teachers use their textbooks influences the way they evaluate the same textbooks; on the other hand, the use of textbooks doesn’t necessarily influence the way teachers adapt them. Moreover, the findings revealed that, in general, due to some particular constraints the Capeverdean English teachers are using their textbooks as resources, in which several textbooks are used in combination with one another. Additionally, although teachers assume that they are doing their best, they still need more confidence concerning the way they use, evaluate and adapt available textbooks. Teachers’ confidence in the way they are using their textbooks can be reinforced by establishing an intensive teacher training module on materials evaluation and adaptation, taking into account that a textbook is one of the most important tools in the process of teaching and learning. I hope that the elements presented may lead to further studies on this matter, specifically regarding textbook evaluation and adaptation.

Non-invasive quantification of brain glycogen absolute concentration.

The only currently available method to measure brain glycogen in vivo is 13C NMR spectroscopy. Incorporation of 13C-labeled glucose (Glc) is necessary to allow glycogen measurement, but might be affected by turnover changes. Our aim was to measure glycogen absolute concentration in the rat brain by eliminating label turnover as variable. The approach is based on establishing an increased, constant 13C isotopic enrichment (IE). 13C-Glc infusion is then performed at the IE of brain glycogen. As glycogen IE cannot be assessed in vivo, we validated that it can be inferred from that of N-acetyl-aspartate IE in vivo: After [1-13C]-Glc ingestion, glycogen IE was 2.2 +/- 0.1 fold that of N-acetyl-aspartate (n = 11, R(2) = 0.77). After subsequent Glc infusion, glycogen IE equaled brain Glc IE (n = 6, paired t-test, p = 0.37), implying isotopic steady-state achievement and complete turnover of the glycogen molecule. Glycogen concentration measured in vivo by 13C NMR (mean +/- SD: 5.8 +/- 0.7 micromol/g) was in excellent agreement with that in vitro (6.4 +/- 0.6 micromol/g, n = 5). When insulin was administered, the stability of glycogen concentration was analogous to previous biochemical measurements implying that glycogen turnover is activated by insulin. We conclude that the entire glycogen molecule is turned over and that insulin activates glycogen turnover.

Interactions between cells and functionalized nanoparticles

In this present thesis Superparamagnetic Iron Oxide Nanoparticles (SPIONs) with 9 nm in diameter were selected as nanocarriers in order to study their potential application as drug delivery systems. Therefore the aim of the study was to demonstrate the proof of concept by establishing an efficient system of drug delivery, which would be a valuable tool in biomedical applications, such as the treatement of cancer, by reducing the side effects due to administration of a high concentration of therapeutic agents. As demonstrated in a previous study, the uptake of SPIONs by tumoral human cells was enhanced by the presence of amino groups on their surface. The stabilization of SPIONs were then performed and optimized by the coating of poly(vinylalcohol) and poly(vinylalcohol/vinylamine). Such nanoparticles were known as aminoPVA-SPIONs. The toxicity and the inflammatory reaction of aminoPVA-SPIONs were evaluated in order to establish their potentiel use in the human body. The results demonstrated that the human cells were able to invaginate aminoPVA-SPIONS without revealing any toxicity and inflammatory reaction. The analysis by transmission electron microscopy (TEM), scanning electron microscopy (SEM), cryo-TEM, confocal microscopy and histological staining (i.e. Prussian Blue) showed that the iron oxide core of SPIONs were located in the cytoplasm of cells and concentrated in vesicles. The evaluation of the mechanism of uptake of aminoPVA-SPIONs revealed that their uptake by monolayer cell culture was performed via an active mechanism, which was achieved by a clathrin-mediated endocytosis. Consequently, it was suggested that aminoPVA-SPIONs were good candidates as nanocarriers in drug delivery systems, which were able to reach the cytoplasm of cells. Their incubation with three-dimensional models mimicing tissues, such as differentiated rat brain cell-derived aggregates and spheroids, revealed that aminoPVA-SPIONs were able to invade into deep cell layers according to the stage of growth of these models. In the view of these promising results, drug-SPIONs were prepared by the functionalization of aminoPVA-SPIONs via a biological labile chemical bond by one of these three antineoplastic agents, which are widely used in clinical practice: 5-fluorourdine (Fur) (an antimetabolite), or camptothecin (CPT) (a topoisomerase inhibitor) or doxorubicin (DOX) (an anthracycline which interfere with DNA). The results shown that drug-SPIONs were internalized by human melanoma cells, as it was expected due the previous results with aminoPVA-SPIONs, and in addition they were active as anticancer agents, suggesting the efficient release of the drug from the drug-SPIONs. The results with CPT-SPIONs were the most promising, whereas DOX- SPIONs did not demonstrate a prononced activity of DOX. In conclusion, the results demonstrated that functionalized iron oxide nanoparticles are a promising tool in order to deliver therapeutic agents. - Dans le cadre de ce travail de thèse, les nanoparticules superparamagnétiques d'oxyde de fer (SPIONs) ayant un diamètre de 9 nm ont été choisies, afin d'étudier leur éventuelle utilisation dans un système de délivrance d'agents thérapeutiques. Ainsi le but de la thèse est de démontrer la faisabilité de fabriquer un système efficace de délivrance d'agents thérapeutiques, qui serait un outil intéressant dans le cadre d'une utilisation biomédicale, par exemple lors du traitement du cancer, qui pourrait réduire les effets secondaires provoqués par le dosage trop élevé de médicaments. Comme il a été démontré dans une précédente étude, l'invagination des SPIONs par des cellules humaines cancéreuses est améliorée par la présence de groupes fonctionnels amino à leur surface. La stabilisation des SPIONs est ainsi effectuée et optimisée par l'enrobage de poly(vinylalcool) et de (poly(vinylalcool/vinylamine), qui sont connues sous le nom de aminoPVA-SPIONs. La toxicité et la réaction inflammatoire des aminoPVA-SPIONs ont été évaluées dans le but de déterminer leur potentielle utilisation dans le corps humain. Les résultats démontrèrent que les cellules humaines sont capables d'invaginer les aminoPVAS-SPIONs sans induire une réaction toxique ou inflammatoire. L'analyse par la microscopie électronique en transmission électronique (TEM), la microscopie électronique à balayage (SEM), le cryo-microscopie électronique (SEM), la microscopie confocale et la coloration histologique (par ex, le bleu de Prusse) a montré que l'oxyde de fer des SPIONs est localisé dans le cytoplasme des cellules et est concentré dans des vesicules. L'évaluation du méchanisme d'invagination des aminoPVA-SPIONs ont révélé que leur invagination par des monocultures de cellules est effectué par un méchanisme actif, contrôlé par une endocytose induite par les clathrins. Par conséquent, les aminoPVA-SPIONs sont de bons candidats en tant que transporteurs (nanocamers) dans un système de délivrance d'agents thérapeuthique, capable d'atteindre le cytoplasme des cellules. Leur incubation avec des modèles tridimenstionnels imitant les tissues, tels que les aggrégats de cellules de cerveau différenciées et les sphéroïdes, a montré que les aminoPVA-SPIONs sont capable de pénétrer dans les couches profondes des modèles, selon l'état d'avancement de leur croissance. En vue de ces résultats prometteurs, les drug-SPIONs ont été préparés en fonctionalisant les aminoPVA-SPIONs par le biai d'une liaison chimique labile par un des trois agents thérapeutiques, déjà utilisé en pratique : 5-fluorourdine (Fur) (un antimétabolite), or camptothecin (CPT) (un inhibiteur de la topoisomerase) or doxorubicin (DOX) (un anthracycline qui interfère avec le DNA). Les résultats ont montré que les drug-SPIONs sont capable d'être internalisés par les mélanomes, comme il a été attendu d'après les résultats obtenus précédemment avec les aminoPVA-SPIONs, et de plus, les drug-SPIONs sont actifs, ce qui suggère un relargage efficace de l'agent thérapeutique du drug-SPIONs. Les résultats obtenus avec les CPT-SPIONs sont les plus prometteurs, tandis que ceux avec les DOX-SPIONs, ce n'est pas le cas, dont l'activité thérapeutique de DOX n'a pas été aussi efficace. En conclusion, les résultats ont pu démontrer que les nanoparticules d'oxyde de fer fonctionnalisées sont un outil prometteur dans la délivrance d'agents thérapeutiques.

Brain injury program to ensure greater access to community-based services, July 11, 2006

More than 2,200 Iowans each year experience a traumatic brain injury that requires hospitalization. Of those, more than 750 will experience long-term disability as a result. According to a 2000 CDC report, there are an estimated 50,000 such individuals living in Iowa – a number similar to the population of Ames. As part of an enterprise-wide effort to ensure that all Iowans, including those with brain injuries, have access to quality healthcare, Governor Tom Vilsack signed the Brain Injury Services program bill on May 23. The bill will allow the Iowa Department of Public Health (IDPH) to implement a one-of-a-kind program to help those with brain injuries and their families in navigating and maximizing the Iowa community-based service system.

Towards a consensus view on understanding nanomaterials hazards and managing exposure

The aim of this article is to present an overview of salient issues of exposure, characterisation and hazard assessment of nanomaterials as they emerged from the consensus-building of experts undertaken within the four year European Commission coordination project NanoImpactNet. The approach adopted is to consolidate and condense the findings and problem-identification in such a way as to identify knowledge-gaps and generate a set of interim recommendations of use to industry, regulators, research bodies and funders. The categories of recommendation arising from the consensual view address: significant gaps in vital factual knowledge of exposure, characterisation and hazards; the development, dissemination and standardisation of appropriate laboratory protocols; address a wide range of technical issues in establishing an adequate risk assessment platform; the more efficient and coordinated gathering of basic data; greater inter-organisational cooperation; regulatory harmonization; the wider use of the life-cycle approaches; and the wider involvement of all stakeholders in the discussion and solution-finding efforts for nanosafety.

European Integration Without EU Membership : Models, Experiences, Perspectives

At the beginning of the 1990s, the concept of "European integration" could still be said to be fairly unambiguous. Nowadays, it has become plural and complex almost to the point of unintelligibility. This is due, of course, to the internal differentiation of EU membership, with several Member States pulling out of key integrative projects such as establishing an area without frontiers, the "Schengen" area, and a common currency. But this is also due to the differentiated extension of key integrative projects to European non-EU countries - Schengen is again a case in point. Such processes of "integration without membership", the focus of the present publication, are acquiring an ever-growing topicality both in the political arena and in academia. International relations between the EU and its neighbouring countries are crucial for both, and their development through new agreements features prominently on the continent's political agenda. Over and above this aspect, the dissemination of EU values and standards beyond the Union's borders raises a whole host of theoretical and methodological questions, unsettling in some cases traditional conceptions of the autonomy and separation of national legal orders. This publication brings together the papers presented at the Integration without EU Membership workshop held in May 2008 at the EUI (Max Weber Programme and Department of Law). It aims to compare different models and experiences of integration between the EU, on the one hand, and those European countries that do not currently have an accession perspective on the other hand. In delimiting the geographical scope of the inquiry, so as to scale it down to manageable proportions, the guiding principles have been to include both the "Eastern" and "Western" neighbours of the EU, and to examine both structured frameworks of cooperation, such as the European Neighbourhood Policy and the European Economic Area, and bilateral relations developing on a more ad hoc basis. These principles are reflected in the arrangement of the papers, which consider in turn the positions of Ukraine, Russia, Norway, and Switzerland in European integration - current standing, perspectives for evolution, consequences in terms of the EU-ization of their respective legal orders1. These subjects are examined from several perspectives. We had the privilege of receiving contributions from leading practitioners and scholars from the countries concerned, from EU highranking officials, from prominent specialists in EU external relations law, and from young and talented researchers. We wish to thank them all here for their invaluable insights. We are moreover deeply indebted to Marise Cremona (EUI, Law Department, EUI) for her inspiring advice and encouragement, as well as to Ramon Marimon, Karin Tilmans, Lotte Holm, Alyson Price and Susan Garvin (Max Weber Programme, EUI) for their unflinching support throughout this project. A word is perhaps needed on the propriety and usefulness of the research concept embodied in this publication. Does it make sense to compare the integration models and experiences of countries as different as Norway, Russia, Switzerland, and Ukraine? Needless to say, this list of four evokes a staggering diversity of political, social, cultural, and economic conditions, and at least as great a diversity of approaches to European integration. Still, we would argue that such diversity only makes comparisons more meaningful. Indeed, while the particularities and idiosyncratic elements of each "model" of integration are fully displayed in the present volume, common themes and preoccupations run through the pages of every contribution: the difficulty in conceptualizing the finalité and essence of integration, which is evident in the EU today but which is greatly amplified for non-EU countries; the asymmetries and tradeoffs between integration and autonomy that are inherent in any attempt to participate in European integration from outside; the alteration of deeply seated legal concepts, and concepts about the law, that are already observable in the most integrated of the non-EU countries concerned. These issues are not transient or coincidental: they are inextricably bound up with the integration of non-EU countries in the EU project. By publishing this collection, we make no claim to have dealt with them in an exhaustive, still less in a definitive manner. Our ambition is more modest: to highlight the relevance of these themes, to place them more firmly on the scientific agenda, and to provide a stimulating basis for future research and reflection.

YRITYKSEN VERKOSTOITUMISKYKY, Verkostoitumisen hyöty- ja haittatasapainon arviointi

Useilla toimialoilla kuten infra-alalla verkostoituminen on ollut vieras käsite. Hankintamallit, lainsäädäntö ja alalle ominaiset lyhytkestoiset projektit ovat olleet kumppanuuksien esteenä. Uudet hankintamallit ja toimijoille asetetut roolijakovaatimukset antavat infra-toimialan yrityksille mahdollisuuksia kumpanuuksien rakentamiseen. Tutkimuksen tavoitteena on löytää syitä ja motiiveja jotka johtavat verkostoitumiseen infra-alalla. Tutkimuksessa esitellään verkostoitumisen näkökulmasta käsin infra-alan keskeisen rakennuttaja-organisaation hankintastrategiaa, sekä siitä muodostettua alan arvoketjua. Verkostoituminen on prosessi, jonka aikana arvioidaan yrityksen kykyä toimia kumppanina. Vertikaalisen verkostoitumisen haasteena on yritysten välille syntyvä yhteinen näkemys toimintatavoista, joilla kahdenvälinen markkinaehtoinen liikesuhde voidaan muuttaa kumppanuudeksi. Tavoitteena on oikean tasapainon löytäminen hyötyjen ja haittojen välillä. Tutkimuksessa esitellään niitä hyötyjä ja haittoja, jotka liittyvät yritystenväliseen vertikaalisen verkostoitumiseen. Tutkimuksessa esitellään myös kaksi valmista verkostoitumistyökalua, jotka on tarkoitettu yritysten käyttöön verkostoitumisprosessin tueksi. Työkalut on valittu siten, että niiden käyttäminen on mahdollista ja hyödyllistä heti verkostoitumisprosessin alku- eli rakennusvaiheessa.

Virtaviivainen LEAN-liiketoiminta

Työn tarkoituksena oli löytää ratkaisu omasta kokemuksesta nousseeseen tarpeeseen, kuinka LEAN-toimintaa tulisi ylläpitää ja organisoida yrityksessä. Samalla halusin ymmärtää, kuinka paljon suomalaisissa yrityksissä LEAN-toiminnasta ja sen johtamisesta tiedetään. Ensiksi kävin lävitse LEAN-teoriaa ja hukkia. Menetelmiä olen käsitellyt lähinnä siitä näkökulmasta, mitä niistä Abloy Oy:ssä voisi parhaiten käyttää yrityksen virtaviivaistamiseen. Työn empiirisessä osassa selvitetään haastattelututkimuksella ongelmakenttään liittyviä kysymyksiä. Merkittäväksi havainnoksi nousi se, että haastateltavat eivät nähneet LEAN-toimintaa erityisen hyvin johdetuksi alueeksi suomalaisissa yrityksissä. Haastatellut olivat sen sijaan melko yksimielisiä siitä, kuinka LEAN-toiminta tulisi organisoida yrityksessä, ja että sen tulisi raportoida korkealle yrityksen hierarkiassa. Tämän työn tulokset auttavat yrityksen LEAN-johtamistyötä. Selkeästi käy ilmi, että LEAN-johtajakoulutusta pitäisi organisoida. Abloy Oy:n johto on tullut tietoiseksi LEAN-toiminnan mahdollisuuksista ja merkityksestä monin tavoin. Ei riitä, että LEAN-työskentelyvain aloitetaan, se täytyy myös organisoida. Yrityksen korkeimman johdon on sitouduttava virtaviivaistamistyöhön. Tässä työssä annetut suositukset organisaation peruspiirteistä voivat edesauttaa yritysjohtoa LEAN-työskentelyn aloittamisessa.
