Comment ne pas perdre la tête? À propos des effets d'intervention dans les interronégatives en comment et de leur suspension dans les questions rhétoriques

Les interrogatives partielles peuvent être marquées par un mot en QU en position initiale de la phrase. Cette position est analysée dans différents cadres génératifs comme mettant en jeu le mouvement du mot QU depuis une position intraprédicative. Ce mouvement serait démontré par le fait qu’il peut être interrompu par différents opérateurs, dont la négation. Cette interruption distinguerait le mouvement des arguments et des non-arguments: les QU sous-catégorisés pourraient passer par-dessus la négation parce que leur prédicat licencie leur trace. Cela prédit que comment, combien, où, pourquoi et quand ne peuvent pas introduire de questions négatives (?* Comment ne lui a-t-il pas parlé?), ce que pourraient qui, que, quoi (À qui n’a-t-il pas parlé?). C’est cette prédiction que teste ce travail qui considère le mot QU comment avec des propositions interrogatives niées. Il se fonde sur le recensement des attestations dans Frantext pour le 20ème siècle, parmi lesquelles prédominent les questions rhétoriques (Comment ne pas perdre la tête?). L’identification de ces dernières face aux interrogations réelles demande des critères que formule ce travail. La raison pour laquelle les questions rhétoriques rendent possible les séquences considérées est envisagée, et sont considérées une hypothèse syntaxique sur un prédicat sous-jacent et une hypothèse interprétative sur le rôle des présuppositions. L’intervention des présuppositions reflète la définition même de la question rhétorique, et suggère que la putative impossibilité des questions négatives avec un QU adverbial tiendrait à des facteurs d’informativité.

Impacts and relationships between three evolving disciplines

This paper is concerned with three evolving disciplines, namely, Management of Technology (MoT), Operations Management (OM) and Supply Chain Management (SCM). These three disciplines have emerged at different times, SCM being the most recent, although they also seem to be concerned, at least in some part, with the same managerial problem areas. Based on this underlying assumption, the paper lays the ground for this special issue of the International Journal of Technology Management, which is devised to provide a platform for discussion concerning the impacts, relationships and possible synergies between the three disciplines that very much seem to be driving the attention of a lot of recent management thinking.

Philosophy, theory, and practice of green operations management

This paper proposes a more profound discussion of the philosophical underpins of sustainability than currently exists in the MOT literature and considers their influence on the construction of the theories on green operations and technology management. Ultimately, it also debates the link between theory and practice on this subject area. The paper is derived from insights gained in three research projects completed during the past twelve years, primarily involving the first author. From 2000 to 2002, an investigation using scenario analysis, aimed at reducing atmospheric pollution in urban centres by substituting natural gas for petrol and diesel, provided the first set of insights about public policy, environmental impacts, investment analysis, and technological feasibility. The second research project, from 2003 to 2005, using a survey questionnaire, was aimed at improving environmental performance in livestock farming and explored the issues of green supply chain scope, environmental strategy and priorities. Finally, the third project, from 2006 to 2011, investigated environmental decisions in manufacturing organisations through case study research and examined the underlying sustainability drivers and decision-making processes. By integrating the findings and conclusions from these projects, the link between philosophy, theory, and practice of green operations and technology management is debated. The findings from all these studies show that the philosophical debate seems to have little influence on theory building so far. For instance, although ‘sustainable development’ emphasises ‘meeting the needs of current and future generation’, no theory links essentiality and environmental impacts. Likewise, there is a weak link between theory and the practical issues of green operations and technology management. For example, the well-known ‘life-cycle analysis’ has little application in many cases because the life cycle of products these days is dispersed within global production and consumption systems and there are different stakeholders for each life cycle stage. The results from this paper are relevant to public policy making and corporate environmental strategy and decision making. Most of the past and current studies in the subject of green operations and sustainability management deal with only a single sustainability dimension at any one time. Here the value and originality of this paper lies in its integration between philosophy, theory, and practice of green technology and operations management.

Nonlinear optical effects manifested by electromagnetic induced transparency in cold atoms

This dissertation reports experimental studies of nonlinear optical effects manifested by electromagnetically induced transparency (EIT) in cold Rb atoms. The cold Rb atoms are confined in a magneto-optic trap (MOT) obtained with the standard laser cooling and trapping technique. Because of the near zero Doppler shift and a high phase density, the cold Rb sample is well suited for studies of atomic coherence and interference and related applications, and the experiments can be compared quantitatively with theoretical calculations. It is shown that with EIT induced in the multi-level Rb system by laser fields, the linear absorption is suppressed and the nonlinear susceptibility is enhanced, which enables studies of nonlinear optics in the cold atoms with slow photons and at low light intensities. Three independent experiments are described and the experimental results are presented. First, an experimental method that can produce simultaneously co-propagating slow and fast light pulses is discussed and the experimental demonstration is reported. Second, it is shown that in a three-level Rb system coupled by multi-color laser fields, the multi-channel two-photon Raman transitions can be manipulated by the relative phase and frequency of a control laser field. Third, a scheme for all-optical switching near single photon levels is developed. The scheme is based on the phase-dependent multi-photon interference in a coherently coupled four-level system. The phase dependent multi-photon interference is observed and switching of a single light pulse by a control pulse containing ∼20 photons is demonstrated. These experimental studies reveal new phenomena manifested by quantum coherence and interference in cold atoms, contribute to the advancement of fundamental quantum optics and nonlinear optics at ultra-low light intensities, and may lead to the development of new techniques to control quantum states of atoms and photons, which will be useful for applications in quantum measurements and quantum photonic devices.

Expertise sportive et entraînement perceptivo-cognitif de l’athlète

Pour être performant au plus haut niveau, les athlètes doivent posséder une capacité perceptivo-cognitive supérieure à la moyenne. Cette faculté, reflétée sur le terrain par la vision et l’intelligence de jeu des sportifs, permet d’extraire l’information clé de la scène visuelle. La science du sport a depuis longtemps observé l’expertise perceptivo-cognitive au sein de l’environnement sportif propre aux athlètes. Récemment, des études ont rapporté que l’expertise pouvait également se refléter hors de ce contexte, lors d’activités du quotidien par exemple. De plus, les récentes théories entourant la capacité plastique du cerveau ont amené les chercheurs à développer des outils pour entraîner les capacités perceptivo-cognitives des athlètes afin de les rendre plus performants sur le terrain. Ces méthodes sont la plupart du temps contextuelles à la discipline visée. Cependant, un nouvel outil d’entraînement perceptivo-cognitif, nommé 3-Dimensional Multiple Object Tracking (3D-MOT) et dénué de contexte sportif, a récemment vu le jour et a fait l’objet de nos recherches. Un de nos objectifs visait à mettre en évidence l’expertise perceptivo-cognitive spécifique et non-spécifique chez des athlètes lors d’une même étude. Nous avons évalué la perception du mouvement biologique chez des joueurs de soccer et des non-athlètes dans une salle de réalité virtuelle. Les sportifs étaient systématiquement plus performants en termes d’efficacité et de temps de réaction que les novices pour discriminer la direction du mouvement biologique lors d’un exercice spécifique de soccer (tir) mais également lors d’une action issue du quotidien (marche). Ces résultats signifient que les athlètes possèdent une meilleure capacité à percevoir les mouvements biologiques humains effectués par les autres. La pratique du soccer semble donc conférer un avantage fondamental qui va au-delà des fonctions spécifiques à la pratique d’un sport. Ces découvertes sont à mettre en parallèle avec la performance exceptionnelle des athlètes dans le traitement de scènes visuelles dynamiques et également dénuées de contexte sportif. Des joueurs de soccer ont surpassé des novices dans le test de 3D-MOT qui consiste à suivre des cibles en mouvement et stimule les capacités perceptivo-cognitives. Leur vitesse de suivi visuel ainsi que leur faculté d’apprentissage étaient supérieures. Ces résultats confirmaient des données obtenues précédemment chez des sportifs. Le 3D-MOT est un test de poursuite attentionnelle qui stimule le traitement actif de l’information visuelle dynamique. En particulier, l’attention sélective, dynamique et soutenue ainsi que la mémoire de travail. Cet outil peut être utilisé pour entraîner les fonctions perceptivo-cognitives des athlètes. Des joueurs de soccer entraînés au 3D-MOT durant 30 sessions ont montré une amélioration de la prise de décision dans les passes de 15% sur le terrain comparés à des joueurs de groupes contrôles. Ces données démontrent pour la première fois un transfert perceptivo-cognitif du laboratoire au terrain suivant un entraînement perceptivo-cognitif non-contextuel au sport de l’athlète ciblé. Nos recherches aident à comprendre l’expertise des athlètes par l’approche spécifique et non-spécifique et présentent également les outils d’entraînements perceptivo-cognitifs, en particulier le 3D-MOT, pour améliorer la performance dans le sport de haut-niveau.

Nonlinear optics with cold Rb atoms using tapered optical nanofibres

Optical nanofibres (ONFs) are very thin optical waveguides with sub-wavelength diameters. ONFs have very high evanescent fields and the guided light is confined strongly in the transverse direction. These fibres can be used to achieve strong light-matter interactions. Atoms around the waist of an ONF can be probed by collecting the atomic fluorescence coupling or by measuring the transmission (or the polarisation) of the probe beam sent through it. This thesis presents experiments using ONFs for probing and manipulating laser-cooled 87Rb atoms. As an initial experiment, a single mode ONF was integrated into a magneto-optical trap (MOT) and used for measuring the characteristics of the MOT, such as the loading time and the average temperature of the atom cloud. The effect of a near-resonant probe beam on the local temperature of the cold atoms has been studied. Next, the ONF was used for manipulating the atoms in the evanescent fields region in order to generate nonlinear optical effects. Four-wave mixing, ac Stark effect (Autler-Townes splitting) and electromagnetically induced transparency have been observed at unprecedented ultralow power levels. In another experiment, a few-mode ONF, supporting only the fundamental mode and the first higher order mode group, has been used for studying cold atoms. A higher pumping rate of the atomic fluorescence into the higher order fibreguided modes and more interactions with the surrounding atoms for higher order mode evanescent light, when compared to signals for the fundamental mode, have been identified. The results obtained in the thesis are particularly for a fundamental understanding of light-atom interactions when atoms are near a dielectric surface and also for the development of fibre-based quantum information technologies. Atoms coupled to ONFs could be used for preparing intrinsically fibre-coupled quantum nodes for quantum computing and the studies presented here are significant for a detailed understanding of such a system.

I Can't Believe It's Not Bakhtin!: Literary Theory, Postmodern Advertising and the Gender Agenda

Taking the literary theories of Mikhail Bakhtin as a starting point, the authors offer three gendered readings of a postmodern advertisement for Moët & Chandon champagne. They commence with a discussion of the influence of gender on textual interpretation; continue with an outline of Bakhtin's key concepts, with particular reference to gender; present three contrasting readings of Moët's postmodern advertisement; and conclude with a discussion of their interpretations together with some reflexive reflections on the gender agenda. Though not claiming to offer a comprehensive introduction to Bakhtin, they do try to exemplify, in a quasi-carnivalesque mode of exposition, something of the character of that supremely gifted thinker and to demonstrate the insights his concepts provide in relation to gendered readings of advertising texts.

Este trabajo estudia la presencia e importancia de las diversiones y el placer en distintos momentos de la vida de la corte de los reyes de Aragón: las prostitutas, dirigidas por el rey Arlot, la música, el juego, el baile o los juglares, observando el aumento de su presencia a lo largo del siglo xiv, con el correlativo aumento de los gastos. También se observa el incremento en el lujo y la complejidad de estas actividades y la siempre mayor presencia de elementos espectaculares como bestias, carros, figuras alegóricas y otros entremeses en coronaciones, bodas o entradas reales, todos ellos aspectos de la progresiva glorificación de la monarquía.

Band manager - Ett Content Management System för musikbranchaktörer

Summit Music Management är ett managementföretag som arbetar med en rad svenska artister. I deras arbetsuppgifter ingår även hantering av artisternas webbplatser, ett arbete som visat sig vara säkerhetskänsligt och svårt att få klart. Målet med projektet har varit att utveckla ett Content Management System för aktörer inom musikbranschen, vars syfte det är att förenkla det dagliga arbetet av dessa webbplatser. Systemet ska innehålla funktionalitet som gör det möjligt att skapa webbplatser åt artisterna samtidigt som det ska gå att underhålla och uppdatera textmaterial såväl som bilder som finns på webbplatserna. Systemet har skapats med tekniker, språk och ramverk som finns tillgängliga under fria licensavtal. Systemets grund är skapat med PHP-ramverket Laravel tillsammans med HTML, CSS och Twitter Bootstrap. Denna del fungerar som gränssnitt för administratörer där användaren kan logga in och skapa webbplatser. De webb-platser som skapas av systemet är skrivna i AngularJS tillsammans med HTML, CSS och Twitter Bootstrap. Mellan dessa delar finns ett REST-api skrivet i Laravel som sköter kommunikationen mellan komponenterna. Systemet arbetar mot en MySQL-databas där all data lagras och hämtas ifrån. Summit Music Management har förutom att leverera text- och bildmaterial, även fungerat somtestpanel för att kunna mäta systemets användbarhet. Testerna visade att systemet kan möta de behov som finns hos Summit Music Management men att det kan komma att behöva vidareutvecklas för att bättre passa en större kundgrupp och för att strama åt säkerhetsaspekterna ytterligare.

Avvägning mellan arbetsmiljö och effektivitet med hjälp av multikriterieanalys : Hur komplettering av kundtjänst påverkar kundnöjdhet och effektivitet

A public organization has a section for customer service which is responsible of order entry from customers concerning errands within real estate and business equipment, cleaning, transport operations and handicap appliance. According to the co-ordinators in hospitals within the organisation the customers are requesting for staff to talk to physically, meaning a person to speak with face to face. The customers experiencing that it’s sometimes difficult to call customer service or use the web form, which is the only communication paths in the current situation. Proposed changes presented claim that a complement to customer service with local service centers in every hospital. The purpose of this study is to evaluate a change proposition by weigh between efficiency and working environment, this by using multi-criteria analysis. To achieve the goal a decision model is designed in the decision tool DecideIT. The aim of the study is to recommend decision makers to choose one of the options based on as rational grounds as possible. The result of the study showed that the preferred alternative is not to supplement customer service with local service centers. For the most part, the result depending on the survey (represented result from working environment criteria) which showed that the majority of customers do not request a person to speak with face to face at all.

Hur ett tvärfunktionellt samarbete kan motverka stuprörsstrukturer : Kommunikationens roll i det organisatoriska gränssnittet mellan olika avdelningar

Stovepipes, or also called silos, appear in many different organizations and sectors and contribute to problems when employees or managers tend to look more to their own, or the individual departments, objectives rather than to the organizations. The purpose of this study was to identify different communicative factors that promote stovepipes in order to further identify the most critical factor to disarm. A case study has been done at a selected company, with a stovepipe structure, in order to achieve the purpose of the study. The case study has included interviews and observations to identify different problem areas which then have been compared with three communicative factors identified in previous studies. The factor that had the most connections to the problem areas have been considered the most critical factor. The result of the study indicates that “A lack of understanding each other's work” is the most critical factor in stovepipe structures and that it can be prevented by following five recommendations: bring up positive collaboration continually, raise problems with each other instead of with others, identify different communication paths in and between the departments, implement a long-term model for preventing stovepipes and set up workshops between the involved departments. The conclusion of the study is that stovepipes create several undesirable effects in the organization but that the efforts to counter these problems do not have to be complicated. Following five small steps into a better collaboration and communication can be enough to be on your way to a better organizational structure.

BeSafe : Säkerhetsapplikation

Examensarbetet beskriver utvecklingen av säkerhetsapplikationen BeSafe vilken utvecklats för IT-konsulttjänsteverksamheten Sogeti. BeSafe kommer i framtiden integreras med två andra applikationer för att tillsammans bilda en större friluftsapplikation. Den färdiga applikationen besvarar de verifierbara målen och därmed även problemformuleringen. Applikationen erbjuder användaren möjlighet att stärka den egna säkerheten. Muntliga intervjuer genomfördes för att bestämma design, färger och logotyp för applikationen. Intervjuerna resulterade i en användarvänligare applikation där undersökningen riktade in arbetet mot det gränssnitt BeSafe nu har. BeSafe är utvecklad genom en iterativ process i utvecklingsmiljön Android Studios och riktar sig till enheter baserade på Androids OS. Vidareutveckling av applikationen skulle kunna ske i form av nya funktioner där användaren exempelvis kan tillåta anhöriga få live feedback på vart användaren befinner sig. Det har tagits hänsyn till etiska aspekter under arbetets gång för att värna om användarens integritet. Detta genom notifikationer, minimering av risk för spridning av data genom lagrings- och kommunikationssätt inom applikationen.

Värdering av kriterier vid stora investeringar : En jämförelse mellan olika intressenters uppskattningar av kriterier

In what way does different stakeholders assess a decision and its consequences, and how do these assessments differ? When a company stands before a big decision, they need to consider aspects that are economic, ecologic and social. To make a good decision they need to consider the society and its different stakeholder groups. This study examined how different groups values and weights different criteria. The study has been done with the project Sundsvall logistics park as a case, with criteria related to that project. The goal of the study was to find a way to value and weight different criteria and then compare how the company and the stakeholders assesses these criteria. This has been done through interviews with relevant people that has got extra knowledge about the project Sundsvall logistics park, and through a survey that has been sent out to residents of Sundsvall. The informants and respondents got to assess values and weights to the criteria relative to an indirect alternative where the logistics park isn’t built. The data was then compiled using multi attribute utility theory as a tool to present the comparison. The result of the study suggests that the differences between the valuations and weightings of the criteria is partly due to an uncertainty in how the logistics park would affect the criteria, but that the biggest reason probably depends on what perspective the person is viewing the logistics park from. If the person is viewing the logistics park from an industrial perspective, the criteria related to industrial development is getting more important and is going to take up more room in the analysis. If the person is viewing the logistics park from an individual and social perspective, the criteria related to that is more important and takes up more room in the analysis.
