Organismos são capazes de diferenciar estímulos sensoriais gerados independentemente pelo ambiente dos estímulos causados por sua própria ação no mundo. Esse processo depende de mecanismos neurais e cognitivos que unam suas ações às percepções por elas geradas. Objetivo desse trabalho foi investigar a interação da ação com a percepção visual no domínio temporal. Em cinco experimentos psicofísicos, foi estudado o efeito modulatório da ação no efeito flash-lag e em tarefas envolvendo estimativas de intervalos temporais. Nossos resultados mostraram que o planejamento e/ou execução de atos motores voluntários são capazes de reduzir em algumas dezenas de milissegundos as latências com que estímulos visuais são percebidos e também de reduzir as estimativas de intervalos temporais. A redução dessas latências é maior quando a conseqüência sensorial da ação é apresentada na fóvea, assim como quando existe um atraso entre a ação e o estímulo por ela causado. / Organisms are able to distinguish between sensory stimuli from the environment and sensory stimuli they cause. This process depends on neural and cognitive mechanisms that link actions to perceptions generated by these actions. This work aimed to investigate the interaction of action and perception in the temporal domain. In five psychophysical experiments, we have assessed the modulation of action in the flash-lag effect and in tasks involving temporal interval estimations. Our results showed that the planning and execution of a voluntary motor action are capable of reducing both visual perceptual latencies and temporal interval estimations. This reduction increases when the sensory consequences of motor actions are presented on the fovea and when a delay is injected between the action and the stimuli caused by it.

Les batteries au lithium tout solide présentent un grand intérêt pour le développement de systèmes de stockage de grande densité (volumique) d'énergie et sûrs notamment en raison de leur excellente stabilité thermique par rapport aux technologies lithium-ions à électrolyte liquide. Cependant, avec l'épaisseur de la batterie, de fortes limitations cinétiques sont observées, en raison i/ de la relativement faible mobilité des ions dans les matériaux inorganiques et ii/ de la présence de joints de grains généralement bloquants aux interfaces solide/solide. De plus au cours de la charge/décharge de la batterie, les matériaux actifs (réservoir de l'énergie) changent de volume ce qui induit des contraintes mécaniques interfaciales qui provoquent la formation de micro-fractures très dommageables à la cyclabilité de ces systèmes. Cette thèse concerne la réalisation et la caractérisation de batteries inorganiques monolithiques (avec les électrodes composites) en utilisant une méthode de frittage: Spark Plasma Sintering (SPS). La formulation des électrodes composites est fondamentale car ce sont de multi-matériaux qui doivent présenter de nombreuses fonctionnalités: 1) une grande densité d'énergie 2) une bonne percolation électronique (resp. ionique) enfin 3) une bonne tenue mécanique avec des interfaces électrodes/electrolyte stables afin d'assurer la durée de vie des cellules.Le principal objectif est de trouver des relations, pour des matériaux donnés, entre la texture des poudres initiales, la microstructure des céramiques obtenues par frittage SPS et les propriétés électriques (électronique et ionique) ainsi que les performances électrochimiques. / All-solid batteries with inorganic solid electrolytes are attractive candidates in electrochemical energy storage since they offer high safety, reliability and energy density. Aiming to increase the surface capacity strong efforts have been made to increase the thickness of the electrode. However, the thicker electrode, the more stress is generated at the solid/solid interfaces because of the volume change of the active material during lithium insertion/desinsertion upon cycling, which leads to formation of micro-cracks between the components and finally a bad cycling life. The possible answer to this issue is to build in place of a dense phase pure electrode, a composite electrode which is a multifunctional material. This composite electrode should contain a lot of electrochemically active material, the reservoir of energy; together with electronic and ionic conductor additives, to ensure efficient and homogeneous transfer of electrons and ions in the electrode volume.The main scope of this thesis was to develop all-solid-state batteries prepared by SPS method for applications at elevated temperatures. These batteries consist of a two composite electrodes separated by the NASICON-type solid electrolyte Li1.5Al0.5Ge1.5(PO4)3. The main objective was to find relationships, for given materials, between the initial powder granulometry (grain size, size distribution, agglomeration), the microstructure of ceramics obtained by SPS sintering, and the electrochemical performances of the final batteries. By creating electrodes with novel materials and better composition, the trade-off of power density and energy density can be minimized.

Tidsperioden mellan räkenskapsårets slut och datumet för påskriven revisionsberättelse benämns audit report lag (ARL). Anledningarna till att ARL uppstår har studerats i stor utsträckning, men de konkreta effekterna som uppstår till följd av ARL är mindre studerade. En tidigare studie om ARL:s samband med ökad risk för aktieprisfall på den kinesiska aktiemarknaden visade på ett positivt samband. På grund av detta samband finns ett intresse att studera om ett liknande samband existerar på den svenska aktiemarknaden. Syftet med studien är att förklara ett eventuellt samband mellan lång ARL och ökad risk för aktieprisfall på den svenska aktiemarknaden. Studien använder sig av en deduktiv ansats och en longitudinell forskningsdesign bestående av kvantitativ data för att försöka förklara ett eventuellt samband mellan lång ARL och en ökad risk för aktieprisfall. Datamaterialet bestod av sekundärdata. Studien finner inget samband mellan lång ARL och ökad risk för aktieprisfall på den svenska aktiemarknaden. Däremot visas svaga indikationer på att kort ARL leder till ökad risk för aktieprisfall på den svenska aktiemarknaden. Studien bidrar med utökad kunskap om sambanden mellan ARL och ökad risk för aktieprisfall. Vidare bidrar studien med kunskap för revisorer, bolagsledningar och investerare om vilka konsekvenser ARL kan ha på börsnoterade bolags aktiekurs. / The time period between the fiscal year end and the audit report date is termed audit report lag (ARL). The determinants of ARL have been frequently studied, however the practical consequences of ARL have not been studied to the same extent. A previous study about ARLs association with stock price crash risk on the Chinese stock market showed a positive association. This association made it interesting to study if a similar association exists on the Swedish stock market. The purpose of this study is to explain a possible association between long ARL and an increased stock price crash risk on the Swedish stock market. This study uses a deductive approach and a longitudinal research design consisting of quantitative data to explain a possible association between long ARL and an increased stock price crash risk. The data set consisted of secondary data. The study finds no association between long ARL and an increased stock price crash risk on the Swedish stock market. However, the study does find weak indications that short ARL leads to an increased stock price crash risk on the Swedish stock market. The study contributes with increased knowledge regarding associations between ARL and an increased stock price crash risk. Furthermore, the study contributes with knowledge for auditors, company management and investors of the consequences ARL can have on listed companies’ stock price.

Housing is a fundamental human need and shapes our everyday lives. People take great care to choosea home that meets their needs through various amenities and attributes, striving to maximize theirutility given their budget. One amenity that is often overlooked is what the building looks like.Research indicates that people prefer classical homes, but very few are being built in classical stylesnowadays. This study utilizes a hedonic price model to explore whether neo-traditional architecturecarries a price premium in Stockholm municipality. It focuses on apartments in multi-family houses,analysing a total of 16,508 observations. A hedonic price model is utilized, with seven OLS modelsrun in RStudio, including a spatial lag model. The findings suggest a price premium of 10.5% with theregular model and 5.8% with the spatial lag model. The study concludes that neo-traditionalarchitecture has a significant effect on apartment prices in Stockholm municipality. / Boende är ett grundläggande mänskligt behov och formar våra vardagsliv. Människor lägger storomsorg på att välja ett hem som uppfyller deras behov genom olika bekvämligheter och egenskaper,och strävar efter att maximera sin nytta inom sin budget. En bekvämlighet som ofta förbises är hurbyggnaden ser ut. Forskning visar att människor föredrar klassiska hem, men väldigt få byggs iklassisk stil nuförtiden. Denna studie använder en hedonisk prismodell för att undersöka om ny-traditionell arkitektur har en prispremie i Stockholms Stad. Den fokuserar på lägenheter i flerfamiljshus och analyserar totalt 16 508 observationer. En hedonisk prismodell används, med sjuOLS-modeller körda i RStudio, inklusive en spatial-lag modell. Resultaten tyder på en prispremie på10,5% med den vanliga modellen och 5,8% med den spatiala fördröjningsmodellen. Studien drarslutsatsen att ny-traditionell arkitektur har en betydande effekt på lägenhetspriserna i Stockholmsstad.

Ce travail traite une investigation systématique des performances du procédé membranaire cyclique par séparation gazeuse. Premièrement, l'état de l'art du procédé membranaire cyclique, les problèmes techniques et la modélisation du transfert à travers la membrane ont été exposés. Deuxièmement, les études théoriques et expérimentales existantes sur le procédé cyclique sont passées en revue. Selon la durée de pression haute et sa fraction dans un cycle, ce genre d'opération est divisé en deux classes: classes courte et longue. D'après cette classification, une analyse systématique de l'intérêt potentiel de la classe courte par rapport aux performances d'une opération en régime permanent a été accomplie par des simulations et optimisations numériques. Par ailleurs, afin d'améliorer la performance, l'usage du MMM dans un tel procédé a été discuté. En parallèle à l'étude sur la classe courte, une nouvelle conception du procédé cyclique de classe longue a été proposée. Les avantages spectaculaires par rapport aux procédés membranaires classiques ont été mis en évidence à l'aide de nos simulations et optimisations. Finalement, une validation expérimentale a été effectuée afin de fournir un support solide à cette nouvelle conception / This study deals with a systematic investigation of the performance of cyclic membrane gas separation processes. First, a state of the art of membrane separation processes, including material challenges and mass transfer modeling issues is proposed. In a second step, a review of the different theoretical and experimental studies performed on cyclic processes is reported. With respect to the length of the high pressure stage and its fraction in one cycle, these operations are classified into short and long classes. Based on this classification, a systematic analysis of the potential interest of short class compared to steady-state operation performances has been achieved by means of numerical simulation and optimization. In order to improve the performance, the use of MMM in such a process has been further discussed. In parallel with the short class study, a design of novel long class has been proposed. Spectacular advantages with respect to classical membrane-based processes have been highlighted by means of our simulation and optimization studies. Finally, an experimental verification has been performed in order to provide a solid support to this novel process

Rapportens undersökning beskriver de skillnader och likheter mellan kedjeägda och privatägda klädbutiker i Lidköping. En öppen intervju genomfördes med fem butikschefer i kedja och fem butikschefer/ägare i privatägd butik för att beskriva rekryteringsprocessen och kunskapsnivån om anställningsformerna, 4-6 §§ Lag (1982:80) om anställningsskydd (LAS). Personalen i en butik är en resurs som tillsammans med butikschefen/ägaren arbetar för att uppnå lönsamhet. Rätt personal är då betydelsefullt för arbetsgivaren och en felrekrytering kan bli kostsamt för företaget. En effektiv och strukturerad rekryteringsprocess leder till rätt person på rätt plats[1]. Rekryteringsprocessens sista delar innefattar anställningsavtalet där anställningsformen ska beslutas för den nyanställda. Enligt 4-6 §§ LAS, finns sex korrekta anställningsformer. Uppsatsens fråga; Hur anställer butikschefer ny personal och kan de förklara anställningsformerna enligt 4-6 §§ LAS? Underfråga; vilka likheter och skillnader finns beroende på om butikschefen är verksam inom kedja eller privatägd butik? Rapportens slutsats beskriver att rekryteringsprocessen skiljer sig ytterst lite åt varandra i klädföretagen. Både kedjor och privatägda butiker utförde en kortsiktig process vid nyanställning. Kunskapsnivån av anställningsformerna skildes åt tydligare beroende på vart butikschefen arbetade. Butikschefer i kedjor besatt en högre kunskap medan butikschefer/ägare i privat butik saknade generellt kännedomen kring anställningsformernas rättigheter och skyldigheter. Inga av de intervjuade har upplevt konsekvenser av brist på kunskap inom 4-6 §§ LAS. Frågan är om det är nödvändigt för butikschefer att besitta denna kunskap? [1]Danilov & Hellgren, april 2010 / The report's survey describes the differences and similarities between a chain and privately-owned clothing stores in Lidköping. An open interview was conducted with five store managers in a chain store and five store managers / owners of the privately owned shop to describe the recruitment process and knowledge on forms of employment, § § 4-6 Lag (1982:80) om anställningsskydd (LAS). The staff in a store is a resource that together with store manager / owner is working to achieve profitability. Right staff is then important for the employer and a wrong recruitment can be costly for the company. An effective and structured recruitment process leads to the right person at the right place. The recruitment process last part includes the employment contract which the employment status is decided for the new recruits. According to § § 4-6 LAS, there are six regular forms of employment. Essay question: How do the store managers employ new staff and do they know the forms of employment according to § § 4-6 LAS?  Sub query: What similarities and differences exist depending on whether the store manager is active within the chain or privately owned shop? Conclusion of the report describing the recruitment process differs very little about each other clothing companies. Both chains and privately owned shops did a short-term process of hiring new staff. The level of knowledge of forms of employment were separated more clearly dependent on each store manager was working. Store managers in chains possessed a higher knowledge while store managers / owners of private store lacked general awareness about the employment status ‘rights and obligations. None of the interviewees have experienced the consequences of lack of knowledge in § § 4-6 LAS. The question is whether it is necessary for store managers to possess this knowledge?

The aim of this essay was to gain a deeper understanding about how school employees interpret and practice school law regarding cyber-bullying that occurs between pupils on the internet. To examine this we used a qualitative method. We completed eight interviews with five teachers, one headmaster, one school welfare officer and one special educationist. These eight school employees were from four different high schools. In our interviews we found that the school employees thought it was difficult to define different concepts within the school law such as in association with the occupation and offensive behaviour which prohibits them from interpreting the school law in the same way. These concepts were what seemed to make the law unclear when it came to situations involving cyber-bullying. We also found that they regarded the equal treatment plan as their most important tool when working with cyber-bullying even though they were uncertain about whether it was practiced when a situation emerged. This because of the school employees´ discretion that seemed to dominate more than what the school law states in most situations when it came to assessing how serious a cyber-bullying situation was and how it should be handled. We also understood that the school employees required more discussions and education regarding cyber-bullying in order to gain a deeper understanding of how to handle the problem. It seemed that cyber-bullying was not a prioritized matter due to that the employees had a lot of other things to attend too.

Fracture to the neck of femur is frequently stabilised with a hip screw system, however the host bone is often weak or osteoporotic. This causes premature failure of the system, commonly by cut-out of the lag screw through the head of the femur. While augmentation of the fixation with bone cement improves the holding power and decreases failure rate, current methods of administering the cement are messy and inaccurate. This project proposes a lag screw design which allows for direct injection of the cement, via the lag screw itself, after the screw has been inserted and correctly positioned in the femur. A method is also suggested to reduce the risk of cement leakage into the joint space when the guide wire has punctured the head of the femur. The design uses a system of holes in the threaded section of a cannulated screw to allow delivery of cement to the desired area; the modified screw was also tested with and without the tip of the screw closed. These design and implantation techniques were compared to the standard design lag screw both with and without bone cement augmentation by traditional methods. Initial testing in a synthetic bone analogue looked promising. The modified screw with closed end performed better in push out tests than the standard screw alone and comparably with the standard screw with cement augmentation. A second phase of testing with the synthetic material was then conducted to more closely represent physiological loading conditions. In this case again the closed ended modified screw with cement augmentation outperformed the original screw and was comparable with the augmented original screw. However, during this phase of testing problems were observed with the synthetic testing material and it was decided to conduct further testing in paired porcine cadaveric femurs. Several further problems occurred in this phase of testing, including the bending of the test screws. It was concluded that the modified screw showed potential in being a more accurate and consistent method of cement augmentation, however neither the synthetic bone analogue or the porcine material was an adequate model of an osteoporotic human femur. If a suitable testing material could be found, continued study of this prototype may prove beneficial.

Detta är en studie som undersökt om det går att kartlägga någon skillnad mellan erfarna och oerfarna tolkar när det gäller deras lag time (eftersläpning). Lag time är tidsspannet från det att tolken hör talarens yttrande till dess att tolken själv producerar motsvarande yttrande. Tidigare forskare (t ex Cokely, 1992  och McDermid, 2014) har sett att detta påverkar resultatet av tolkningen och därför är detta intressant att undersöka närmare utifrån ett erfarenhetsperspektiv. I studien spelades tre erfarna och tre oerfarna tolkar in när de tolkade ett delvis förskrivet rollspel. Efter inspelningen analyserades materialet genom att i olika segment kontrollera med tidtagarur hur långt efter talaren tolken producerade ett yttrande liknande originaltalets. Resultatet visade att det inte var någon genomgående större skillnad mellan erfarna och oerfarna tolkar i deras lag time. I denna grupp var det istället individuella variationer.  Däremot upptäcktes det att det är svårt att identifiera hur man definierar och mäter lag time. / This is a study which explored the possibility to map a difference between experienced and inexperienced interpreters in their use of lag time. Lag time is the time difference from when the interpreter hears an utterance until the interpreter him/herself starts producing an equivalent utterance. Earlier researchers (for example Cokely, 1992 and McDermid, 2014) have found that this affects the result of the interpretation and that is why this is interesting to explore from a perspective of interpreting experience. In this study three inexperienced interpreters and three experienced interpreters were recorded during a partly scripted role play. After the recording, the material was analyzed by using a stop watch to see how far behind the interpreter’s utterance was produced after the speaker’s utterance in different segments. The result showed that it was not a general difference between the experienced and inexperienced interpreters in their lag time, instead there were individual differences. What was also found is that it is difficult to identify how to define and measure lag time.
