Bensiinin valmistus Naantalin jalostamolla

Työn tarkoituksena oli kartoittaa ja dokumentoida nykyinen bensiininvalmistusprosessi Fortumin Naantalin erikoistuotejalostamolla. Tavoitteena oli löytää nykyisestä prosessista pullonkauloja logistiikkasimulaattorilla sekä hakea ratkaisuja, joilla niitä voitaisiin poistaa. Bensiiniä voidaan valmistaa joko panosprosessina tai linjasekoituksella. Panosprosessissa bensiinikomponentit siirtolinjataan yksitellen valmistussäiliöön, jossa ne sen jälkeen sekoitetaan valmiiksi tuotteeksi. Tällä tavoin valmistetaan bensiiniä Fortumin Naantalin jalostamolla. Linjasekoitusmenetelmässä bensiinikomponentit syötetään kaikki yhtäaikaa linjaan, jossa ne sekoittuvat. Sekoituksen apuna voidaan käyttää linjassa staattisia sekoittimia. Linjasekoitusmenetelmällä saadaan suoraan säiliöön valmista tuotetta. Tällaista menetelmää käytetään Fortumin Porvoon jalostamolla. Bensiinin valmistuksen kaksi tärkeintä muuttujaa ovat höyrynpaine ja oktaaniluku. Esimerkeissä on esitetty panosprosessi- ja linjasekoitusmalleja eri jalostamoilla eripuolilla maailmaa. Naantalin jalostamon bensiininvalmistuksen logistiikkaa kuvaava malli valmistettiin kokeellisessa osassa Tecnomatix Technologiesin kehittämällä eMPlant-simulointiohjelmistolla. Bensiininvalmistuksen logistisiin ongelmakohtiin keskityttiin simulointimallia laadittaessa. Naantalin jalostamoa kuvaavan simulointimallin lisäksi rakennettiin kaksi vaihtoehtoista mallia parantamaan jalostamon bensiinivalmistuksen logistiikkaa. Ensimmäisessä vaihtoehdossa suurennettiin kahta bensiininvalmistuslinjaa, ja toisessa otettiin käyttöön uusi säiliö BE98 valmistusta varten. Vaihtoehtoisten mallien rakentamisen tavoitteena oli saada tietoa mahdollisia investointipäätöksiä varten. Tulosten perusteella uuden valmistussäiliön käyttöönottoa voidaan pitää teknisesti kannattavana. Taloudellisesti hanke on kannattava, jos uuden säiliön rakentamisen sijaan on mahdollisuus vapauttaa jokin olemassa oleva säiliö tähän käyttöön. Yksi simulointimallin kehityskohde on sen käyttöliittymän muuntaminen käyttäjäystävällisempään muotoon. Tällöin tuotannonsuunnittelija voisi käyttää mallia tuotannonsuunnittelun apuna. Mallin tarkentaminen vastaamaan paremmin nykyistä valmistusprosessia on myös yksi kehityskohde.

A territorial approach to R&D subsidies: Empirical evidence for Catalonian firms

Using a database of 2,263 responses to R&D public calls in Catalonia, during the period 2007–2010, this paper proceeds to analyse the potential interaction of the territorial and policy dimensions with the propensity to apply for, and be awarded, a public R&D subsidy. Controlling for characteristics at the firm and project level, we estimate models using a twostep procedure. In the first step, our results suggest that large firms which export and which belong to high-tech manufactures are more likely to participate in a public R&D call. Furthermore, both urban location and past experience of such calls have a positive effect. Our territorial proxy of information spillovers shows a positive sign, but this is only significant at intra-industry level. Membership of one of the sectors prioritized by the Catalan government, perhaps surprisingly, does not have a significant impact. In the second step, our results show that cooperative projects, SMEs or old firms shows a positive effect on the probability of obtaining a public subsidy. Finally, the cluster policy does not show a clear relationship with the public R&D call, suggesting that cluster policies and R&D subsidies follow different goals. Our results are in line with previous results in the literature, but they highlight the unequal territorial distribution of the firms which apply and the fact that policymakers should interlink the decision criteria for their public call with other policies.

The effects of cocoa on the immune system

Cocoa is a food relatively rich in polyphenols, which makes it a potent antioxidant. Due to its activity as an antioxidant, as well as through other mechanisms, cocoa consumption has been reported to be beneficial for cardiovascular health, brain functions, and cancer prevention. Furthermore, cocoa influences the immune system, in particular the inflammatory innate response and the systemic and intestinal adaptive immune response. Preclinical studies have demonstrated that a cocoa-enriched diet modifies T-cell functions that conduce to a modulation of the synthesis of systemic and gut antibodies. In this regard, it seems that a cocoa diet in rats produces changes in the lymphocyte composition of secondary lymphoid tissues and the cytokines secreted by T cells. These results suggest that it is possible that cocoa could inhibit the function of Th2 cells, and in line with this, the preventive effect of cocoa on IgE synthesis in a rat allergy model has been reported, which opens up new perspectives when considering the beneficial effects of cocoa compounds. On the other hand, cocoa intake modifies the functionality of gut-associated lymphoid tissue by means of modulating IgA secretion and intestinal microbiota. The mechanisms involved in these influences are discussed here. Further research may elucidate the cocoa compounds involved in such an effect and also the possible medical approaches to these repercussions

Toimintolaskennan käyttöönotto on eräs mahdollisuus toiminnan ja mittariston jatkokehittämiseen sekä kustannustietojen ja hinnoittelun tarkkuuden parantamiseen.

Cardiovascular magnetic resonance imaging techniques for motion-suppressed multi-dimensional coronary artery imaging with high spatial and temporal resolution

L'imagerie par résonance magnétique (IRM) peut fournir aux cardiologues des informations diagnostiques importantes sur l'état de la maladie de l'artère coronarienne dans les patients. Le défi majeur pour l'IRM cardiaque est de gérer toutes les sources de mouvement qui peuvent affecter la qualité des images en réduisant l'information diagnostique. Cette thèse a donc comme but de développer des nouvelles techniques d'acquisitions des images IRM, en changeant les techniques de compensation du mouvement, pour en augmenter l'efficacité, la flexibilité, la robustesse et pour obtenir plus d'information sur le tissu et plus d'information temporelle. Les techniques proposées favorisent donc l'avancement de l'imagerie des coronaires dans une direction plus maniable et multi-usage qui peut facilement être transférée dans l'environnement clinique. La première partie de la thèse s'est concentrée sur l'étude du mouvement des artères coronariennes sur des patients en utilisant la techniques d'imagerie standard (rayons x), pour mesurer la précision avec laquelle les artères coronariennes retournent dans la même position battement après battement (repositionnement des coronaires). Nous avons découvert qu'il y a des intervalles dans le cycle cardiaque, tôt dans la systole et à moitié de la diastole, où le repositionnement des coronaires est au minimum. En réponse nous avons développé une nouvelle séquence d'acquisition (T2-post) capable d'acquérir les données aussi tôt dans la systole. Cette séquence a été testée sur des volontaires sains et on a pu constater que la qualité de visualisation des artère coronariennes est égale à celle obtenue avec les techniques standard. De plus, le rapport signal sur bruit fourni par la séquence d'acquisition proposée est supérieur à celui obtenu avec les techniques d'imagerie standard. La deuxième partie de la thèse a exploré un paradigme d'acquisition des images cardiaques complètement nouveau pour l'imagerie du coeur entier. La technique proposée dans ce travail acquiert les données sans arrêt (free-running) au lieu d'être synchronisée avec le mouvement cardiaque. De cette façon, l'efficacité de la séquence d'acquisition est augmentée de manière significative et les images produites représentent le coeur entier dans toutes les phases cardiaques (quatre dimensions, 4D). Par ailleurs, l'auto-navigation de la respiration permet d'effectuer cette acquisition en respiration libre. Cette technologie rend possible de visualiser et évaluer l'anatomie du coeur et de ses vaisseaux ainsi que la fonction cardiaque en quatre dimensions et avec une très haute résolution spatiale et temporelle, sans la nécessité d'injecter un moyen de contraste. Le pas essentiel qui a permis le développement de cette technique est l'utilisation d'une trajectoire d'acquisition radiale 3D basée sur l'angle d'or. Avec cette trajectoire, il est possible d'acquérir continûment les données d'espace k, puis de réordonner les données et choisir les paramètres temporel des images 4D a posteriori. L'acquisition 4D a été aussi couplée avec un algorithme de reconstructions itératif (compressed sensing) qui permet d'augmenter la résolution temporelle tout en augmentant la qualité des images. Grâce aux images 4D, il est possible maintenant de visualiser les artères coronariennes entières dans chaque phase du cycle cardiaque et, avec les mêmes données, de visualiser et mesurer la fonction cardiaque. La qualité des artères coronariennes dans les images 4D est la même que dans les images obtenues avec une acquisition 3D standard, acquise en diastole Par ailleurs, les valeurs de fonction cardiaque mesurées au moyen des images 4D concorde avec les valeurs obtenues avec les images 2D standard. Finalement, dans la dernière partie de la thèse une technique d'acquisition a temps d'écho ultra-court (UTE) a été développée pour la visualisation in vivo des calcifications des artères coronariennes. Des études récentes ont démontré que les acquisitions UTE permettent de visualiser les calcifications dans des plaques athérosclérotiques ex vivo. Cepandent le mouvement du coeur a entravé jusqu'à maintenant l'utilisation des techniques UTE in vivo. Pour résoudre ce problème nous avons développé une séquence d'acquisition UTE avec trajectoire radiale 3D et l'avons testée sur des volontaires. La technique proposée utilise une auto-navigation 3D pour corriger le mouvement respiratoire et est synchronisée avec l'ECG. Trois échos sont acquis pour extraire le signal de la calcification avec des composants au T2 très court tout en permettant de séparer le signal de la graisse depuis le signal de l'eau. Les résultats sont encore préliminaires mais on peut affirmer que la technique développé peut potentiellement montrer les calcifications des artères coronariennes in vivo. En conclusion, ce travail de thèse présente trois nouvelles techniques pour l'IRM du coeur entier capables d'améliorer la visualisation et la caractérisation de la maladie athérosclérotique des coronaires. Ces techniques fournissent des informations anatomiques et fonctionnelles en quatre dimensions et des informations sur la composition du tissu auparavant indisponibles. CORONARY artery magnetic resonance imaging (MRI) has the potential to provide the cardiologist with relevant diagnostic information relative to coronary artery disease of patients. The major challenge of cardiac MRI, though, is dealing with all sources of motions that can corrupt the images affecting the diagnostic information provided. The current thesis, thus, focused on the development of new MRI techniques that change the standard approach to cardiac motion compensation in order to increase the efficiency of cardioavscular MRI, to provide more flexibility and robustness, new temporal information and new tissue information. The proposed approaches help in advancing coronary magnetic resonance angiography (MRA) in the direction of an easy-to-use and multipurpose tool that can be translated to the clinical environment. The first part of the thesis focused on the study of coronary artery motion through gold standard imaging techniques (x-ray angiography) in patients, in order to measure the precision with which the coronary arteries assume the same position beat after beat (coronary artery repositioning). We learned that intervals with minimal coronary artery repositioning occur in peak systole and in mid diastole and we responded with a new pulse sequence (T2~post) that is able to provide peak-systolic imaging. Such a sequence was tested in healthy volunteers and, from the image quality comparison, we learned that the proposed approach provides coronary artery visualization and contrast-to-noise ratio (CNR) comparable with the standard acquisition approach, but with increased signal-to-noise ratio (SNR). The second part of the thesis explored a completely new paradigm for whole- heart cardiovascular MRI. The proposed techniques acquires the data continuously (free-running), instead of being triggered, thus increasing the efficiency of the acquisition and providing four dimensional images of the whole heart, while respiratory self navigation allows for the scan to be performed in free breathing. This enabling technology allows for anatomical and functional evaluation in four dimensions, with high spatial and temporal resolution and without the need for contrast agent injection. The enabling step is the use of a golden-angle based 3D radial trajectory, which allows for a continuous sampling of the k-space and a retrospective selection of the timing parameters of the reconstructed dataset. The free-running 4D acquisition was then combined with a compressed sensing reconstruction algorithm that further increases the temporal resolution of the 4D dataset, while at the same time increasing the overall image quality by removing undersampling artifacts. The obtained 4D images provide visualization of the whole coronary artery tree in each phases of the cardiac cycle and, at the same time, allow for the assessment of the cardiac function with a single free- breathing scan. The quality of the coronary arteries provided by the frames of the free-running 4D acquisition is in line with the one obtained with the standard ECG-triggered one, and the cardiac function evaluation matched the one measured with gold-standard stack of 2D cine approaches. Finally, the last part of the thesis focused on the development of ultrashort echo time (UTE) acquisition scheme for in vivo detection of calcification in the coronary arteries. Recent studies showed that UTE imaging allows for the coronary artery plaque calcification ex vivo, since it is able to detect the short T2 components of the calcification. The heart motion, though, prevented this technique from being applied in vivo. An ECG-triggered self-navigated 3D radial triple- echo UTE acquisition has then been developed and tested in healthy volunteers. The proposed sequence combines a 3D self-navigation approach with a 3D radial UTE acquisition enabling data collection during free breathing. Three echoes are simultaneously acquired to extract the short T2 components of the calcification while a water and fat separation technique allows for proper visualization of the coronary arteries. Even though the results are still preliminary, the proposed sequence showed great potential for the in vivo visualization of coronary artery calcification. In conclusion, the thesis presents three novel MRI approaches aimed at improved characterization and assessment of atherosclerotic coronary artery disease. These approaches provide new anatomical and functional information in four dimensions, and support tissue characterization for coronary artery plaques.

El resultado global: una aproximación de la información contable a la realidad de los mercados

Un elemento novedoso que incorporan las cuentas anuales es el resultado global, como nuevo concepto de resultado (que incorpora el tradicional resultado neto más o menos los ajustes en patrimonio neto) en sintonía con la realidad de los mercados. En nuestro trabajo analizamos si la información derivada del resultado global, en el período 2009-2011 para las empresas del IBEX 35, añade más poder informativo al análisis de los estados financieros y en especial a las rentabilidades como indicadores de la realidad de los mercados.

Projektin sisäinen viestintä. Työntekijäryhmien viestintäkäsitykset järjestelmäprojektin käyttöönottovaiheesta nykypäivään, tapaustutkimus Tieliikelaitoksessa

Tutkielman tavoitteena on selvittää, mitä piirteitä ja eroja on löydettävissä eri työntekijäryhmien käsityksissä sisäisen viestinnän toimivuudesta ja mitä ominaisuuksia nämä käsitykset heijastavat yhteisöstä. Tavoitteeseen pyritään laadullisella tapaustutkimuksella, jossa tutkimusmenetelmänä käytetään teemahaastattelua. Tutkimuksen perusteella voidaan todeta projektin sisäisen viestinnän piirteiden heijastavan hyvin viestinnän eri toimintaympäristöjä. Projektin sisällä toimintaympäristöt voidaan erottaa jopa työntekijäryhmittäin. Viestintäkäsitykset paljastavat myös sisäisen viestinnän jatkuvan muutostilan, joka voidaan havaita integroivan ja dissipatiivisen viestinnän vahvuuksien vaihtelulla. Tutkimus vahvisti käsitystä pelkän integroivan viestinnän riittämättömyydestä sisäisen viestinnän myönteisenä kokemiseen. Nykypäivänä myös mekanistisesti toimivissa ympäristöissä tulisi edistää horisontaalisia, vuorovaikutuksellisia ja avoimia kommunikaatiokäytäntöjä. Tutkimus vahvisti edelleen käsitystä johdon ja esimiesten näkyvyyden ja kuuluvuuden merkityksestä hallita mekanistisessa ympäristössä, mutta johdolta odotetaan myös yhä enemmän dialogiin perustuvien viestintävalmiuksien hallintaa. Ymmärtämällä kolmen erilaisen toimintaympäristön olemassaolo, voidaan sisäisen viestinnän resursseja kohdistaa tehokkaasti ympäristön ominaisuuksien ja tavoitteiden suuntaisesti.

Differential associations of personal and general just-world beliefs with the Five-Factor and HEXACO models of personality.

Recent literature evidences differential associations of personal and general just-world beliefs with constructs in the interpersonal domain. In line with this research, we examine the respective relationships of each just-world belief with the Five-Factor and the HEXACO models of personality in one representative sample of the working population of Switzerland and one sample of the general US population, respectively. One suppressor effect was observed in both samples: Neuroticism and emotionality was positively associated with general just-world belief, but only after controlling for personal just-world belief. In addition, agreeableness was positively and honesty-humility negatively associated with general just-world belief but unrelated to personal just-world belief. Conscientiousness was consistently unrelated to any of the just-world belief and extraversion and openness to experience revealed unstable coefficients across studies. We discuss these points in light of just-world theory and their implications for future research taking both dimensions into account.

Vancomycin-associated nephrotoxicity, a case control study

Background: Vancomycin is a cornerstone antibiotic for the management of severe Gram positive infections. However, high doses of vancomycin are associated with a risk of nephrotoxicity. This study aimed to evaluate the relationship between the evolution of vancomycin trough concentration and the occurrence of nephrotoxicity, and to identify risk factors for both vancomycin-associated nephrotoxicity and vancomycin overexposure. Methods: A total of 1240 patients records from our hospital therapeutic drug monitoring database between 2007 and 2011 were screened and grouped according to predefined criteria defining vancomycin overexposure (one or more occurrence of a trough level ≥ 20 mg/L) and treatment-related nephrotoxicity (rise of serum creatinine by ≥ 50% over baseline). A representative sample of 150 cases was selected for in depth analysis. Weighted logistic regression analyses were used to test associations between vancomycin overexposure, nephrotoxicity and other predictors of interest. Results: Patients with high trough concentrations were found to be more likely to develop nephrotoxicity (odds ratio: 4.12; p <0.001). Specific risk factors, notably concomitant nephrotoxic treatments and comorbid conditions (heart failure), were found to independently increase the risk of either nephrotoxicity or vancomycin exposure. Finally, the exploration of temporal relationships between variations of vancomycin trough concentrations and creatinine levels were in line with circular causality with some antecedence of vancomycin on creatinine changes. Conclusion: Our results confirm the important nephrotoxic potential of vancomycin and indicate that the utilisation of this drug deserves thorough individualization for conditions susceptible to increase its concentration exposure and reactive adjustment based on therapeutic drug monitoring.

Short-Term Heparin Kinetics during Catheter Ablation of Atrial Fibrillation.

BACKGROUND: Percutaneous catheter ablation of atrial fibrillation (CA-AF) is a treatment option for symptomatic drug-refractory atrial fibrillation (AF). CA-AF carries a risk for thromboembolic complications that has been minimized by the use of intraprocedural intravenous unfractionated heparin (UFH). The optimal administration of UFH as well as its kinetics are not well established and need to be precisely determined. METHODS AND RESULTS: A total 102 of consecutive patients suffering from symptomatic drug-refractory AF underwent CA-AF. The mean age was 61 ± 10 years old. After transseptal puncture of the fossa ovalis, weight-adjusted UFH bolus (100 U/kg) was infused. A significant increase in activated clotting time (ACT) was observed from an average value of 100 ± 27 seconds at baseline, to 355 ± 94 seconds at 10 min (T10), to 375 ± 90 seconds at 20 min (T20). Twenty-four patients failed to reach the targeted ACT value of ≥300 seconds at T10 and more than half of these remained with subtherapeutic ACT values at T20. This subset of patients showed similar clinical characteristics and amount of UFH but were more frequently prescribed preprocedural vitamin K1 than the rest of the study population. CONCLUSIONS: In a typical intervention setting, UFH displays unexpected slow anticoagulation kinetics in a significant proportion of procedures up to 20 minutes after infusion. These findings support the infusion of UFH before transseptal puncture or any left-sided catheterization with early ACT measurements to identify patients with delayed kinetics. They are in line with recent guidelines to perform CA-AF under therapeutic anticoagulation.

Etelä-Savon energiatase 2006

The aim of this thesis is to create the energy balance from county of South Savo and 20 municipalities comprising the year 2006. The energy balance is restricted to county and municipality borders. Purpose of energy balance is to clarify the present state of energy supply and present information for future decisions. The main objectives for the future are e.g. replacing oil with renewable energy sources and exploiting the forest reserves of South Savo more effectively. Today South Savo is known as being one of the forerunners in use of renewable energy. The growing demand for energy is in South Savo mostly covered with renewable energy sources such as forest chips. The initial data for this thesis is gathered from local energy companies and energy producers. This thesis also exploits formerly made energy balances, publications and statistic from different organisations. The literature study of thesis begins with the basic information about South Savo and energy sources used in the year 2006. Following the thesis includes the energy balance consisting of primary energy sources and consumption of energy. Rest of the thesis includes facts about carbon dioxide emissions, future energy sources and conclusions of results, reliability and expected use of this thesis. Results of this thesis define well the present state of South Savo and are in line with county goals. The results will be used as an aid for policy-making and for considering the condition of current energy supply in South Savo. The method of doing this energy balance can be adapted for other counties as well.

Elastic properties and secondary structure formation of single-stranded DNA at monovalent and divalent salt conditions

Single-stranded DNA (ssDNA) plays a major role in several biological processes. It is therefore of fundamental interest to understand how the elastic response and the formation of secondary structures are modulated by the interplay between base pairing and electrostatic interactions. Here we measure force-extension curves (FECs) of ssDNA molecules in optical tweezers set up over two orders of magnitude of monovalent and divalent salt conditions, and obtain its elastic parameters by fitting the FECs to semiflexible models of polymers. For both monovalent and divalent salts, we find that the electrostatic contribution to the persistence length is proportional to the Debye screening length, varying as the inverse of the square root of cation concentration. The intrinsic persistence length is equal to 0.7 nm for both types of salts, and the effectivity of divalent cations in screening electrostatic interactions appears to be 100-fold as compared with monovalent salt, in line with what has been recently reported for single-stranded RNA. Finally, we propose an analysis of the FECs using a model that accounts for the effective thickness of the filament at low salt condition and a simple phenomenological description that quantifies the formation of non-specific secondary structure at low forces.

Signs of a vector's adaptive choice: on the evasion of infectious hosts and parasite-induced mortality

Laboratory and field experiments have demonstrated in many cases that malaria vectors do not feed randomly, but show important preferences either for infected or non-infected hosts. These preferences are likely in part shaped by the costs imposed by the parasites on both their vertebrate and dipteran hosts. However, the effect of changes in vector behaviour on actual parasite transmission remains a debated issue. We used the natural associations between a malaria-like parasite Polychromophilus murinus, the bat fly Nycteribia kolenatii and a vertebrate host the Daubenton's bat Myotis daubentonii to test the vector's feeding preference based on the host's infection status using two different approaches: 1) controlled behavioural assays in the laboratory where bat flies could choose between a pair of hosts; 2) natural bat fly abundance data from wild-caught bats, serving as an approximation of realised feeding preference of the bat flies. Hosts with the fewest infectious stages of the parasite were most attractive to the bat flies that did switch in the behavioural assay. In line with the hypothesis of costs imposed by parasites on their vectors, bat flies carrying parasites had higher mortality. However, in wild populations, bat flies were found feeding more based on the bat's body condition, rather than its infection level. Though the absolute frequency of host switches performed by the bat flies during the assays was low, in the context of potential parasite transmission they were extremely high. The decreased survival of infected bat flies suggests that the preference for less infected hosts is an adaptive trait. Nonetheless, other ecological processes ultimately determine the vector's biting rate and thus transmission. Inherent vector preferences therefore play only a marginal role in parasite transmission in the field. The ecological processes rather than preferences per se need to be identified for successful epidemiological predictions.

Une justice plus commerciale qu'industrielle ? Comparaison des attentes d'une « bonne justice » en Suisse

Le but de cet article est triple. D'abord, nous identifions les qualités d'une bonne justice en Suisse, telles que défi nies par les différents acteurs qui forment le tribunal au sens large (juges, gestionnaires de tribunaux, avocats, journalistes, politiciens). Deuxièmement, nous vérifions si ces qualités peuvent coexister avec les valeurs véhiculées par le monde managérial (NGP). Enfin, nous évaluons la manière dont elles cohabitent (hybridation, dominance des unes sur les autres, etc.). Pour ce faire, nous avons analysé une série d'entretiens (56) semi-structurés menés dans des tribunaux de première et seconde instance dans des cours civiles, administratives et criminelles, dans les trois régions linguistiques du pays. Les résultats montrent que les groupes d'acteurs interviewés ont des attentes relativement similaires et qu'elles ne semblent pas être incompatibles avec celles de l'univers managérial. Cependant, lorsqu'ils décrivent la bonne justice, les participants font plus souvent appel à des notions liées au monde commercial qu'au monde industriel contrairement à d'autres études menées auprès d'employés du secteur public suisse, mais dans la lignée de ceux du Québec. L'article ouvre la voie à des recherches ultérieures dont l'objectif sera de tester ces conclusions. Abstract The purpose of this paper is threefold. First, we identify the qualities of good justice in Switzerland, as defi ned by the various actors who form the tribunal in a broad sense (judges, court managers, lawyers, journalists, politicians). Second, we verify if these qualities are compatible with the values conveyed by the managerial universe (NPM). Finally, we evaluate how they coexist (hybridization, dominance over each other, etc.). To do this, we analysed a series of semi-structured interviews (56) conducted in tribunals of fi rst and second instance in civil, administrative,and criminal courts in the three linguistic regions of the country. The results show that the groups of actors interviewed have relatively similar expectations that do not seem to be incompatible with those of the managerial world. However, when describing good justice, the participants refer more frequently to concepts related to the commercial than the industrial world, contrary to other Swiss public servants but in line with those of Quebec, as uncovered by former studies. The article opens up the path to further research whose objective will be to test those conclusions.

Electrostimulation mapping of comprehension of auditory and visual words.

In order to spare functional areas during the removal of brain tumours, electrical stimulation mapping was used in 90 patients (77 in the left hemisphere and 13 in the right; 2754 cortical sites tested). Language functions were studied with a special focus on comprehension of auditory and visual words and the semantic system. In addition to naming, patients were asked to perform pointing tasks from auditory and visual stimuli (using sets of 4 different images controlled for familiarity), and also auditory object (sound recognition) and Token test tasks. Ninety-two auditory comprehension interference sites were observed. We found that the process of auditory comprehension involved a few, fine-grained, sub-centimetre cortical territories. Early stages of speech comprehension seem to relate to two posterior regions in the left superior temporal gyrus. Downstream lexical-semantic speech processing and sound analysis involved 2 pathways, along the anterior part of the left superior temporal gyrus, and posteriorly around the supramarginal and middle temporal gyri. Electrostimulation experimentally dissociated perceptual consciousness attached to speech comprehension. The initial word discrimination process can be considered as an "automatic" stage, the attention feedback not being impaired by stimulation as would be the case at the lexical-semantic stage. Multimodal organization of the superior temporal gyrus was also detected since some neurones could be involved in comprehension of visual material and naming. These findings demonstrate a fine graded, sub-centimetre, cortical representation of speech comprehension processing mainly in the left superior temporal gyrus and are in line with those described in dual stream models of language comprehension processing.
