O Trypanosoma (Herpetosoma) rangeli é um protozoário hemoflagelado de ciclo heteroxênico. Apesar de não ser patogênico para o hospedeiro mamífero, incluindo seres humanos, infecções por este parasito podem dificultar o diagnóstico da doença de Chagas. Vários aspectos relativos ao curso da infecção do T. rangeli no hospedeiro mamífero são controversos, incluindo o mecanismo de invasão e multiplicação celular neste hospedeiro. A enzima Oligopeptidase B (OpB) está fortemente relacionada com o processo de invasão celular e patogenicidade de vários tripanosomatídeos, sendo um alvo promissor para o desenvolvimento de quimioterápicos. A OpB de T. rangeli é codificada por uma ORF de 2.139 pb que é traduzida para um polipeptídeo de 713 aminoácidos com 80.2 kDa de massa molecular. A sequência aminoacídica da OpB de T. rangeli, que corresponde a família das prolil endopeptidases, apresenta similaridade de 89,9% com T. cruzi, 86% com T. brucei e 85,5% com T. evansi, estando o domínio catalítico característico da família bastante conservado entre estes organismos. A OpB é expressa nas formas epimastigotas e tripomastigotas de T. rangeli, sendo sua atividade mensurada através da emissão de fluorescência resultante da mobilização de Ca+2 da célula hospedeira em ensaios in vitro. Os extratos proteicos das formas tripomastigotas de T. rangeli apresentaram uma emissão de fluorescência estatisticamente significativa (p < 0,01) em relação aos controles. O tratamento dos extratos proteicos com o soro anti-OpB reduziu a emissão da fluorescência de todos os extratos, no entanto, apenas para os extratos das formas tripomastigotas de T. cruzi essa redução foi significativa. A OpBr teve uma emissão de fluorescência próxima do basal revelando ausência de atividade da proteína recombinante. A avaliação da expressão da OpB durante a interação parasitos/célula hospedeira mostrou um aumento significativo (p < 0,01) da expressão da OpB em T. rangeli após trinta minutos de interação em relação aos parasitos que não entraram em contato com as células. Estes resultados demonstram o envolvimento da OpB no processo de interação do T. rangeli com a célula do hospedeiro mamífero, constituindo um importante alvo de estudo para o esclarecimento do processo de interação parasito/célula.

Full textAbstract:
Due to the development towards more dense programmable devices (FPGAs) it is today possible to fit a complete embedded system including microprocessor, bus architecture, memory, and custom peripherals onto one single reprogrammable chip, it is called a System-on-Chip (SoC). The custom peripherals can be of literally any nature from I/O interfaces to Ethernet Media Access Controllers. The latter core, however, usually consumes a big part of a good sized FPGA. The purpose of this thesis is to explore the possibilities of interfacing an FPGA based Microblaze system to an off-chip Ethernet MAC/PHY. A solution which would consume a smaller part of the targeted FPGA, and thus giving room for other on-chip peripherals or enable the use of a smaller sized FPGA. To employ a smaller FPGA is desirable since it would reduce power consumption and device price. This work includes evaluation of different available Ethernet devices, decision of interface technology, implementation of the interface, testing and verification. Since the ISA interface still is a common interface to Ethernet MAC devices a bus bridge is implemented linking the internal On-Chip Peripheral Bus (OPB) with the ISA bus. Due to delivery delays of the selected Ethernet chip a small on-chip ISA peripheral was constructed to provide a tool for the testing and verification of the bus bridge. The main result of this work is an OPB to ISA bus bridge core. The bridge was determined to work according to specification, and with this report at hand the connection of the Ethernet chip to the system should be quite straightforward.

Full textAbstract:
Bakgrund: I dagsläget upplever verkstadschefen vid OPS att materialplaneringsprocessen skulle kunna effektiviseras. I dagsläget är det oklart hur processen utförs och vad logistikerna lägger ner tid på i varje aktivitet. Genom en kartläggning och jämförelse med en annan verkstad vid Xylem Inc. i Emmaboda finns möjligheten till att se på vilket sätt andra verkstäder arbetar med materialplaneringsprocessen. Syfte: Att identifiera nuläget genom att beskriva och kartlägga materialplaneringsprocessen vid de två verkstäderna OPS och OPX för att identifiera var det förekommer skillnader mellan de två verkstäderna och vad som orsakar onödig tidsåtgång. Syftet är också att utifrån jämförelsen ge förbättringsförslag för att tidseffektivisera materialplaneringsprocessen vid verkstaden OPS. Metod: Studien är en kvalitativ fallstudie på verkstäderna OPS och OPX på Xylem Inc. i Emmaboda där datainsamlingen skett genom semi-strukturerade intervjuer och direkta observationer. Först genomfördes processkartläggning av materialplaneringsprocessen vid de två verkstäderna tillsammans med tidtagning av delprocessernas tidsåtgång. Utifrån detta kunde sedan en jämförelse mellan de två verkstäderna utföras. Efterföljande kapitel i studien fokuserar på vad verkstaden OPS kan göra för att tidseffektivisera materialplaneringsprocessen. Slutsatser: Det förekommer skillnader mellan de två verkstädernas arbetssätt på endast en av delprocesserna men det är väsentlig skillnad i tidsåtgång på samtliga delprocesser. Tidsåtgången kan härledas från otillräcklig kapacitet i verkstaden OPS och genom olika förslag på frigörelse av kapacitet samt uppdaterade och anpassade system kan verkstaden OPS tidseffektivisera materialplaneringsprocessen.Background: In today´s situation the workshop manager feel that the material planning process at workshop OPS can be more efficient. The reason for this is that in the current situation, it is unclear how the process is carried out and what the logistics are put in time in every activity. Through a survey and comparison with another workshop at Xylem Inc. in Emmaboda it is possible to see how the workshops makes them different and what causes the time required for the material planning process. Purpose: To identify the current situation be describing and mapping materials planning process at the two workshops OPS and OPX to identify where there are differences between the two workshops and what causes unnecessary delays. It also aims based on the comparison suggest measures to streamline the time material planning at the workshop OPS. Method: The study is a qualitative case study of the workshops OPS and OPX at Xylem Inc. in Emmaboda where data collection occurred through semi-structured interviews and direct observations. First conducted process mapping of materials planning process at the two workshops together with the timing of the time spent on each sub-process. Based on this, a comparison could be made of the two workshops. The remaining chapter of the study focuses on what the workshop OPS can do to be more time-efficient on their material planning process. Conclusion: There are differences between the two workshops working on only one of the sub-processes but there is considerable difference in the time needed in every part of the process. The duration can be derived from insufficient capacity in the workshop OPS and through various suggestions for the emancipation of capacity as well as updated and adapted systems can workshop OPS time-efficiency materials planning process.

Full textAbstract:
Cette thèse porte sur la diffusion volontaire d informations lors d OPA/OPE. Elle est constituée de trois articles s intéressant à une étape différente du processus de diffusion d informations dans ce contexte. Le premier article vise à expliquer la décision de diffusion volontaire des entreprises cibles par une étude des facteurs incitatifs à la diffusion lors de telles opérations. Les résultats montrent que cette décision découle principalement de l influence de facteurs contextuels. Le deuxième article identifie, à partir d une analyse lexicale des communiqués de presse volontaires, les stratégies discursives adoptées par les entreprises acquéreuses et cibles ainsi que les motivations sous-jacentes. Enfin, dans le troisième article, une expérimentation est conduite afin d examiner l influence des stratégies de diffusion d informations et de gestion des impressions des entreprises cibles d offres hostiles sur les actionnaires. Il s avère que celles-ci modifient leur perception de l offre et in fine leur décision d accepter ou de rejeter l opérationThis thesis deals with voluntary disclosure of information during takeover bids. It consists of three articles that are concerned with a different step of the disclosure process in this context. The first article aims at explaining the voluntary disclosure decision of target companies by studying factors influencing disclosure during such transactions. The results highlight that this decision is mainly explained by the influence of contextual factors. The second article identifies, through a lexical analysis of voluntary press releases, the discourse strategies adopted by both bidding and target companies and the underlying motivations. Finally, in the third article, an experiment is conducted to investigate the influence of disclosure and impression management strategies of the targets of hostile bids on shareholders. It turns out that these strategies modify their perception of the bid and ultimately their decision to accept or reject the bid

Full textAbstract:
L'objectif de cette recherche est l'analyse des motivations des prises de contrôle ainsi que l'explication des rentabilités anormales observées autour de la date d'annonce. Il s'agit aussi de tester un modèle explicatif de la rentabilité. Le modèle est une fonction de la prime, du type d’opérations, de la participation préalable et de la dispersion du capital de la société initiatrice. L'étude a été menée sur un échantillon de cinquante-cinq opérations d'O. P. A. Et d' O. P. E. Réalisées sur le marché parisien entre 1977 et 1991. La procédure d'offre publique se distingue des autres opérations d'acquisition par sa discrétion et par le fait qu'elle s'adresse directement aux actionnaires de la société visée. Ensuite, l'étude théorique des motivations a été menée aussi bien dans le cadre de la théorie traditionnelle de la firme que celui de la prise en compte des divergences d'intérêt entre les actionnaires et les dirigeants. Les principales motivations de ces opérations sont : la synergie, les coûts d'agence et l'erreur d'évaluation de la part des dirigeants de l'entreprise initiatrice (surévaluation ou sous-évaluation). La méthodologie utilisée est celle de l’analyse d'évènements. Les résultats montrent que l'évolution de la rentabilité autour de la date d'annonce est différente entre l'échantillon d'entreprises acquéreuses et acquises. De même les rentabilités sont plus importantes pour les O. P. A. Que pour les O. P. E. Le test du modèle montre que, pour les O. P. A. , c'est la prime qui est la variable la plus déterminante pour expliquer les rentabilités. Concernant les O. P. E. , le modèle échoue quant à expliquer celles-ciIn this reserach we analyse the gains and motivations of takeover operations. We also build a model of the return around the announcement date of the operation. The variables are : the premium of the offer, the type of operation, the previous holding of target shares and the dissipation of the acquiring firm shares. The study was conducted from a sample of fifty five french cash and stock tender offers between 1977 and 1991. The takeover in France is different from the other acquisition rechniques because its discreet and applies only to the shareholders of the target firm. The theoritical study of the motivations was led according to the traditionnal theory of the firm and also in the case of difference of interest between the shareholders and managers. The main motivations o f the operations are : the ssynergy, the agency costs and the over or under evaluation of the target firm by the acquiri ng firms managers. The methodology used is an event study. The resuts show that the abnormal returns are different in the sample of acquiri ng and target firms, also they are higher for cahs tender offers than in stock ones. The test of the model shows that, for cash tender offers the premium is the main variable to explain the returns around the announcement date. For stock tender offers the model fail in explaining returns

Full textAbstract:
Negli ultimi anni, l’automazione dei processi produttivi sta causando un incremento esponenziale della quantità e delle tipologie di oggetti interconnessi e comunicanti negli impianti di produzione. Tutti questi sistemi devono essere in grado di comunicare tra di loro, nonché che con applicativi HMI (Human-Machine Interface) e gestionali, per scambiarsi tutte le informazioni utili al processo produttivo, e devono poterlo fare in maniera rapida e sicura.
La tesi in oggetto analizza nel dettaglio il protocollo OPC Unified Architecture, una soluzione per lo scambio di informazioni in ambito industriale.
Vengono studiati i servizi offerti da OPC UA che, essendo forniti in maniera astratta e con mapping su varie tecnologie, lo rendono indipendente dalla piattaforma e dal mezzo di comunicazione.
Viene poi analizzato nel dettaglio lo standard di Information Modelling di OPC UA, che permette di gestire virtualmente ogni genere di informazione e dà la possibilità ai venditori di modellare tipi di dato complessi specifici alle loro esigenze.
L’architettura di sicurezza di OPC UA è un altro punto di attenzione, in grado di garantire confidenzialità e non ripudiabilità dei dati.
Grazie al concetto dei profili e alle innumerevoli modalità di comunicazione offerte, viene spiegato come OPC UA costituisce come una valida soluzione per una gamma molto ampia di prodotti, da sistemi embedded per il rilevamento dati a software MES ed ERP.
Infine, vengono introdotti alcuni stack OPC UA open source, e per uno di essi è presentata una demo software.

OPS-SAT is an in-orbit laboratory mission designed to allow experimenters todeploy new on-board software and perform in-orbit demonstrations of new tech-nology and concepts related to mission operations. The NanoSat MO Frame-work facilitates the process of developing experimental on-board software for OPS-SAT by abstracting the complexities related to communication across the space toground link as well as the details of low-level device access. The objective of thisproject is to implement functional simulation models of OPS-SAT peripherals andorbit/attitude behavior, which integrated together with the NanoSat MO Frame-work provide a sufficiently realistic runtime environment for OPS-SAT on-boardsoftware experiment development. Essentially, the simulator exposes communi-cation interfaces for executing commands which affect the payload instrumentsand/or retrieve science data and telemetry. The commands can be run either fromthe MO Framework or manually, from an intuitive GUI which performs syntaxcheck. In this case, the output will be displayed for advanced debugging. The endresult of the thesis work is a virtual machine which has all the tools installed todevelop cutting edge technology space applications.

Full textAbstract:
The present study attempted to explore the role cultural values play on the relations between personality variables and organizational citizenship behavior (OCB). Specifically, Schwartz' cultural values of hierarchy and egalitarianism and the personality predictors of conscientiousness and agreeableness were examined. It was hypothesized that hierarchy and egalitarianism would moderate the relationship between conscientiousness, agreeableness and OCB. Specific hypotheses concerning the direction of the influence on particular dimensions of OCB were tested. Data were collected from multiple organizations resulting in a sample of 62 pairs of employee-supervisor dyads from the U.S. and 64 pairs from China. Results indicated that agreeableness correlated significantly with OCB toward individuals and that hierarchy moderated the relationship between conscientiousness and OCB toward the organization. The other hypotheses were not supported. Limitations of the study and implications for future research were also discussed.

Full textAbstract:
À la suite de l’endosymbiose, le génome chloroplastique a rétréci et dépend maintenant du génome nucléaire pour son expression. Chez Chlamydomonas reinhardtii, les protéines Octotricopeptide repeat (OPR), codées dans le noyau, contrôlent l’expression d’ARNm chloroplastiques spécifiques. La répétition OPR est un motif dégénéré de 38 acides aminés, qui forme un tandem d’hélices α antiparallèles qui lient l’ARN. Une répétition OPR est prédite pour interagir avec un nucléotide spécifique grâce à des résidus variables à des positions précises. La succession de répétitions permet aux protéines OPR de se lier à une séquence donnée. En partant d’un « code OPR » théorique, j’ai cherché à étudier cette spécificité de reconnaissance. J’ai mute in vivo les cibles chloroplastiques de facteurs OPR pour empêcher l’interaction OPR/ARN, puis j’ai tenté de la restaurer en mutant les résidus conférant la spécificité dans les répétitions correspondantes. Étonnamment, les interactions OPR/ARN sont très résilientes, ce qui a complétement changé notre vision de ces interactions in vivo. Des études fonctionnelles complémentaires que j’ai réalisées sur les facteurs OPR MDB1 and MTHI1 ont révélé que l’expression des gènes chloroplastiques dépend probablement de systèmes de facteurs nucléaires. En coopérant ces facteurs auraient une affinité combinée plus forte et seraient ainsi plus résilientsFollowing endosymbiosis, the chloroplast genome shrunk and became reliant on the host genome for its expression. In Chlamydomonas reinhardtii, Octotricopeptide repeat proteins (OPR), encoded in the nucleus, control the expression of a specific organellar mRNA. The OPR repeat is a degenerate motif of 38 amino-acids, folding into a tandem of antiparallel α-helices which can bind to RNA. An individual OPR repeat is predicted to interact with one given nucleotide thanks to specificity-conferring residues at defined positions within the repeat. OPR proteins contain tracks of successive OPR motifs, thus they can bind to a specific RNA “target” sequence and act on it. I aimed to study this specificity, called the “OPR code”, starting with a draft code based on known OPR protein/mRNA couples. I mutated in vivo the chloroplast targets of some OPR factors to disrupt the OPR/RNA interaction, and then tried to restore it by mutating the specificity-conferring residues in the corresponding repeats. Surprisingly, OPR/RNA interactions seem very resilient, challenging our view of how the specificity is established in vivo. Complementary functional studies that I performed on the OPR factors MDB1 and MTHI1 revealed that chloroplast gene expression might rely on complex networks of nuclear factors. By cooperating those putative systems would be both more specific and more resilient

Full textAbstract:
Syftet med det här examensarbetet är att utreda OPC-standarderna OPC Data Access och motsvarande del i OPC Unified Architecture, samt att implementera OPC-kommunikation i ett system. Behovet av en kommunikationsstandard föddes ur det interoperabilitetsproblem som fanns inom framförallt industriella produktionssystem. Med ett OPC-gränssnitt implementerat mellan en datakälla och applikation kan datautbytet ske på ett standardiserat sätt. OPC Foundation, som är en organisation som tillhandahåller olika OPC-standarder, har idag utvecklat två OPC-standarder, Classic OPC och OPC Unified Architecture. Classic OPC består av ett antal specifikationer som är baserade på COM- och DCOM-gränssnitten, vilket gör att dessa specifikationer är bundna till Windowsplattformen. OPC Unified Architecture erbjuder ett säkrare och mer mångsidigt kommunikationsgränssnitt än vad Classic OPC-standarden ger, tack vare dess kommunikationsstack. Den praktiska biten i projektet bestod av att implementera OPC-kommunikation i ett system. Två delmoment som ingick i implementeringen var att skapa en testmiljö samt att utveckla en applikation ovanpå klassbibliotek som behandlade kommunikation mot OPC DA- respektive OPC UA-servrar. OPC Unified Architecture-standarden definierar endast formatet på meddelandet innan det kommer fram till kommunikationsstacken. Det här öppnar upp för möjligheten att i framtiden erbjuda kommunikationsstackar som kommunicerar enligt andra protokoll och formateringar, vilket gör att OPC Unified Architecture kommer att kunna anpassas efter framtida behov och på så sätt kommer att vara ett alternativ för interoperabilitet i system under en lång tid framöver.The purpose of this thesis is to investigate the OPC standard OPC Data Access and the corresponding part in OPC Unified Architecture, and to implement OPC communication in a system. The need for a communication standard was born out of the interoperability problems that existed mainly in industrial production systems. With an OPC interface implemented between a data source and an application, the data exchange can be done in a standardized way. OPC Foundation, which is an organization that provides various OPC standards, has now developed two OPC standards, Classic OPC and OPC Unified Architecture. Classic OPC is a set of specifications that are based on COM and DCOM interfaces, which means that these specifications are tied to the Windows platform. OPC Unified Architecture provides a safer and more versatile communications interfaces than the Classic OPC standard provides, thanks to the communication stack. The practical bit of the project consisted of implementing OPC communication in a system. Two parts that were included in the implementation was to create a test environment and to develop an application on top of the class library that dealt with communication with OPC DA and OPC UA servers. The OPC Unified Architecture standard defines only the format of the message before it reaches the communication stack. This makes it possible to provide communication stacks that communicate according to other protocols and formats in the future, which allowing OPC Unified Architecture to be adaptable to future needs and thus will be an option for an interoperable system for a long time to come.

Full textAbstract:
Background: Ballad Health participates in the Centers for Medicare and Medicaid Services’ (CMS) Accountable Health Communities (AHC) model. The AHC model is evaluating if universal screening, referral, and navigation services for health-related social needs (HRSN) can improve outcomes and reduce unnecessary utilization and costs of health care services. To ensure the evaluation of the model has sufficient statistical power, navigation services are expected to be provided to a minimum number of individuals. The purpose of this study is to analyze the characteristics of Ballad Health’s AHC navigation services that could be modified to improve opt-in rates.
Methods: The primary outcome measure was identified as whether a beneficiary contacted via telephone opted-in or –out of the navigation program. Andersen’s Behavioral Model for Health Service Use was used as the conceptual framework for selecting covariates of interest. Enabling factors were of primary interest because alternate interventions may be designed around them. Data was pulled for the time period of November 17, 2018 through February 14, 2019. Where possible, covariates were associated with data from CMS’ AHC Data Template v3.1 to accommodate replication for all AHC bridge organizations, though additional internally-collected data, which may not be available for all bridge organizations, were needed for some variables. Chi-squared tests were performed for each covariate.
Results: No statistical differences were found for the primary covariates of interest. Opt-in rates by Navigator were lowest for Navigator 5 and highest for Navigator 4 (67.53% and 88.24%). Opt-in rates by weekday of decision were lowest on Thursdays and highest on Wednesdays (64.91% and 77.42%). Opt-in rates based on time of day were lowest between 8:00am and 9:59am, and highest between 12:00pm and 1:59pm (62.50% and 100%). Opt-in rates were lowest when the decision was made six days after the screening and highest when made the same day (53.57% and 83.33%). Opt-in rates were lowest when there were five weekdays between screening and navigation decision, and highest when there were three weekdays between the screening and decision (60% and 90%). Other non-process covariates of interest that were statistically significant for opt-in rates were the presence of either food, safety, or utility needs.
Conclusions: Several groups had higher opt-in rates that were not statistically significant; small sample sizes may have impacted the significance of these differences. For example, opt-in rates were higher when made the same day as the screening than when made one day after (83.33% and 74.79%). However, only 18 beneficiary decisions were made on the same day, while 119 were made one day after. Increasing the number of same-day phone call attempts may be a method to improve opt-in rates. Importantly, date and time data for contact attempts before a beneficiary decides to opt-in or opt-out were unavailable as of the time of the analysis. These data are captured and will be added to the analysis when available, which could provide more insight into whether a beneficiary is more likely to opt-in or opt-out.

Även fast de flesta kanske skulle tänka på en industri när de hör talas om ett övervakande system, är det något som ökar inom fastighetsautomation idag. I och med att dagens byggnader blir mer intelligenta ökar behovet av att ha full koll på alla delar i ett fastighetssystem. Genom att implementera ett överordnat system, också kallat för SCADA system, kan en fastighet övervakas från ett och samma ställe vilket ger användaren full koll på vad som händer i en byggnad. Målet med detta arbete är att beskriva kommunikationen mellan ett överordnat och ett underliggande system samt att realisera ett SCADA system. Först beskrivs hur ett överordnat system fungerar och det följs upp med en utredning kring kommunikationsstandarden som ligger till grund för hur ett fungerande SCADA sedan kan implementeras. Med tanke på dagens användning av internet väcks genast frågan kring hur säkert ett liknande system kan implementeras i ett hus utan att det kan hackas av utomstående, vilket besvaras utifrån teorin. Slutsatsen är den att ett överordnat system har väldigt stor potential med tanke på att nästintill varje hushåll idag har internet och en dator eller mobil enhet. Kan man bortse från säkerhetsriskerna och hur stor kostnaden kan tänkas bli för att köpa sig ett liknande system är detta framtiden i våra hushåll.Even though you probably first of all would think about industries when you hear about a monitoring system its something that is increasing in building automation today. As today's buildings become more intelligent, the need to gain full control of all parts of the system increases. By implementing a superiorvisory system, also known as a SCADA system, a property can be monitored from one location, giving the user a full overview of what's happening in the building. The aim of this work is to describe the communication between a supervisory and underlying system and to put togheter a small SCADA system. First of all is a description of how a superior system works and is followed up with an investigation about the chosen communication standard. A standard that underlies how a functional SCADA then can be implemented. Keep in mind of today's use of the Internet, it is at instance a question of how safe a similar system can be implemented in a house without being worried about third parties hacking your system. The conclusion is that this sort of system have a big potential when almost everyone has a computer and Internet at home. If you can neglect the security risks and how much the cost may be to buy a similar system is that this is the future in our houses.

Dissertação para obtenção do Grau de Mestre em
Engenharia InformáticaDomain Specific Modeling (DSM) is a methodology to provide programs or system’s specification at higher level of abstraction, making use of domain concepts instead of low level programming details. To support this approach, we need to have enough expressive power in terms of those domain concepts, which means that we need to develop new languages , usually termed Domain Specific Languages (DSLs). An approach to execute specifications developed using DSLs goes by applying a model transformation technique to produce a specification in another language. These transformation techniques are applied sucessively until the specification reaches a language with an implemented run-time. The language named Concurrent Object-Oriented Petri Nets (CO-OPN) is being used successfully as a target language for such model transformation techniques. CO-OPN is an object-oriented formal language for specifying concurrent systems, that separates coordination from computational tasks. CO-OPN offers mechanisms to define the system structure and behavior, and like DSLs, relieves the developer from stipulate how that structure and behavior are attained by the underlying system. The currently available code generator for CO-OPN only produces sequential code, despite of this language potential of expressing specifications rich in concurrent behavior. The generated sequential code can be executed either in a Sequential Run-Time or in the step simulator, which is part of CO-OPN Builder IDE. The generation of sequential code turns out to be an adversity to CO-OPN application since concurrent specifications cannot be executed in parallel and therefore this languages potential is not fully exploited. This dissertation aims at filling this CO-OPN’s execution gap, through the development of a Parallel Run-Time. The new Run-Time is achieved through the adaptation of the sequential code generator and actual execution support mechanisms. In this manner, all concurrent specifications that target CO-OPN benefit from thread safe code, ready for execution in parallel and distributed environments, relieving the developer from delving into parallel programming details.By guaranteeing a safe execution environment, CO-OPN becomes an alternative to the way parallel software is nowadays developed.

Full textAbstract:
The disposal of nuclear waste is highly regulated and the disposal option will be dependent on the radionuclide content of the waste. The encapsulation of nuclear waste to prevent migration of radionuclides into the environment and as a safe means of long term storage and disposal can be achieved using ordinary Portland cement (OPC) and various additives such as blast furnace slag (BFS) or pulverised fly ash (PFA). Treated radioactive wastes in this manner are characterised by good thermal, chemical, physical stability and compressive strength. In addition the alkaline chemistry of concrete renders most radionuclides highly insoluble. The ultimate destination of some of these encapsulated wastes is in a Deep Geological Facility (GDF), where for many years the wastes will remain inert to their environment. In the longer-term the environmental conditions will change and the inertness of these waste forms could be affected from the seepage of water into the facility along with microbial activity. The diffusivity or leaching behaviour of cement encapsulated radioactive waste is crucial to ensure the overall safety of a storage/disposal system. The research presented in this thesis evaluates the diffusivity of strontium, caesium and cobalt when added as inactive forms to BFS:OPC and PFA:OPC formulation as their chlorides and for strontium when added as chloride and carbonate. The cylindrical cement paste samples (CPS) having diameter of 3.2 cm and height 5.3 cm were immersed in re-circulating test solutions consisting of de-ionised water, concentrated Sellafield pore water (CSPW), diluted Sellafield pore water (DSPW) and bacterial inoculated water, John Innes Soil Solution (JISS). Strontium carbonate was selected to determine the influence of a water insoluble compound on diffusivity of the cation. Freshly cured and aged BFS:OPC samples were also studied to evaluate the impact of carbonation on cation diffusivity. Chloride salts were used, as these would be benign to microorganisms, i.e. would not stimulate or support growth unlike nitrate or sulphate anions. The outcome of this study indicate that the make-up water composition affected the segregation of inherent and added cations in the cement paste samples and also both the bleed water volume and physical characteristics of the cement paste samples. Strontium when added as a soluble salt to the make-up water influenced the rate of diffusivity. Depending on the type of formulation (BFS:OPC, PFA:OPC), a direct correlation was observed between diffusivity of Sr2+ and total amount of Ca2+ present in the CPS. The rate of diffusivity and the depth of cation diffusion was significantly higher in 3% SrCl2 PFA:OPC having lower concentration of Ca2+ compared to its BFS counterpart. The concentration of the added salt to the make-up water also affected the diffusivity. The difference in the diffusivity was observed between closed and open diffusivity system. The solubility limits were not a factor in open circuit which was comparable with the pH values; contrary to the closed circuits. The concentration of cations and anions in the test solution influenced strontium and caesium diffusivity. The diffusivity of sulphate was influenced by the nature of the cation added to the make-up water. Strontium had the greatest effect on lowering the diffusion primarily due to the formation of sparingly soluble strontium sulphate. The pH values of the circulating JISS test solutions from all the contaminated cement samples were lower in comparison with control, which was comparable with viable population in the circulating system. There was no significant viable population measured in the JISS from control CPS. The JISS test solution composition retard strontium diffusivity but accelerated caesium diffusion in comparison with distilled water values, this retardation could be due to the inherent sulphate content (≈8600 ppb) of the JISS test solution. This work provides fundamental understanding of the physic-chemical factors influencing the diffusivity of cations from BFS:OPC and PFA:OPC formulations. The scheme i.e. closed circuit recirculation adopted in this research would be more fitting of the real situation i.e. stagnation followed by percolation and therefore diffusivity of ions will be greatly influenced by the test solution chemistry and composition.

Quality of Service (QoS) differentiation is the differentiated traffic-handling toachieve multiple service classes of varying quality. In addition to providing serviceguarantees necessary for delay-sensitive, real-time applications, service differentiation can provide increased income for network providers due to price differentiation opportunities. Moreover, with advances in technology, previous QoS schemes based on buffered networks cannot be used in newer, bufferless, optical networks.Current and future technologies were studied to facilitate economic analysis ofQoS differentiation in Optical Packet Switched networks. Empirical data fromrelated studies have been adopted to quantify a relationship between objectivemeasurements of network quality and a user’s willingness to pay for that quality.Models that represent network scenarios with and without service differentiationwere discussed to address the viability of implementation. The model developedsuggests pricing for customer classes based on network parameters before and after implementation, cost of deployment, customer willingness to pay, and businessrequirements such as Return on Investment. It was determined that under certaincircumstances, a network provider may improve revenue via service differentiation.

Detta examensarbete jämför två övervakningsverktyg för servrar i ett nätverk, Zabbix och op5 Monitor. Båda är open source och används aktivt av organisationer för att övervaka organisationsservrarnas processorlast, I/O-kö på hårddiskarna, status på tjänster och mycket mer. Dessa två övervakningsverktyg testas och jämförs med varandra ur perspektiven användarvänlighet, funktionalitet och prestanda. Resultaten visar att i de flesta fallen är Zabbix mer användarvänligt medan op5 Monitor i de flesta fallen har bättre funktionalitet. Det visar sig också att op5 Monitor har något högre prestanda än inte bara Zabbix utan även de övervakningssystem som testades av Robin Rudeklint år 2010.

Full textAbstract:
I en hårdnande marknad för tillverkande industrier krävs det att förbättringar och effektiviseringar av produktionen hela tiden prioriteras, det gäller även Scanias växellådstillverkning. I takt med att antalet växellådsvarianter ökar, ökar utmaningarna kopplat till styrning och planering av produktion. Denna studie syftar till att ta fram ett förslag på det bästa sättet att styra produktionsflödet genom testningen av växellådor i de testriggar som finns samt att ge ett förslag på hur uppföljningen av produktionen ska gå till. Syftet mynnade ut i en teoretisk och en praktisk frågeställning. Den teoretiska frågeställningen behandlar sekvenseringen, vilka mätetal som ska användas i produktionen och hur de ska presenteras samt om takttid eller cykeltid ska användas som styrningsmetod vid testriggarna. Den praktiska formuleringen behandlade de praktiska hinder som uppstår vid de existerande systemen på grund av de nya förslagen. Studien avgränsade sig från implementering av förslagen. För att uppfylla syftet och besvara frågeställningarna skapades två simuleringsprogram i Python som undersökte sekvenseringen och jämförde takttid och cykeltid som styrningsmetod för testriggarna. Verklig data från produktionen användes för att kunna simulera skillnaderna mellan styrningsförslagen på ett tillförlitligt sätt. I testriggarna utförs arbetet av maskin och operatör parallellt med varandra. Simuleringsprogrammen fokuserade främst på maskinarbetet, därför utfördes kompletterande tidsstudier över operatörsarbetet vid testriggarna. För att få ytterligare perspektiv gjordes dessutom två benchmark i form av besök vid motortillverkningen och bearbetningen av pinjonger och kronhjul på Scania i Södertälje. Studien visade att cykeltidsstyrning är att föredra framför takttidsstyrning vid testriggarna. Vid en övergång från takttidsstyrning till cykeltidsstyrning kommer kapaciteten att förbättras och stopptidsmätningarna bli mer tillförlitliga. De fördelar som annars finns vid en takttidsstyrning fungerar inte vid testriggarna på grund av hur de är utformade. Den stora variationen i cykeltider vid testriggarna medför stora problem vid en takttidsstyrning. Från operatörstidmätningen framgick att det går att förbättra arbetet med standardiserat arbetssätt. Simuleringsprogrammet för sekvenseringen visade att en förbättrad sekvens inte ger något i nuläget, men att det kan komma att förändras framöver. Nya mätetal definierades, både i den dagliga produktionen och för vidare analys i ett IT-system. Framförallt utvecklades mätetal för stopptid som även visar vad för typ av stopptid som uppkommer.

Full textAbstract:
Abstract
The current study investigated the relationship between demands for organizational citizenship behaviors and future displays of organizational citizenship and counterproductive work behaviors. Such demands are conceptualized as workplace conditions that make it difficult for employees to complete their job (i.e., organizational constraints), performance failures of coworkers such as incomplete or incorrectly done tasks (i.e., coworker failure) and direct or indirect request from the supervisors to commit more organizational citizenship behaviors (i.e., supervisor pressure). Additionally, the effect of negative affectivity, hostile attribution bias, attributions of blame, and target specific scales of workplace behaviors were investigated. The design of the current study is prospective with a one week time lag between two self-report surveys. 464 employed U.S. residents were recruited through Amazon's M-Turk service. Of the initial 464 participants, 183 also completed the second survey a week later. New scales were created to assess coworker failure, supervisor pressure, attributions of blame, and target specific behaviors. The evidence from this study suggests that coworker failure and supervisor pressure are both antecedents to future displays of organizational citizenship behaviors and counterproductive work behaviors. Similarly, organizational citizenship behaviors preceded demands for organizational citizenship behaviors reported a week later. The results differed slightly when using target-specific scales of behavior. The hypotheses regarding individual differences and attributions of blame were not supported.

Data integration is at the heart of a significant portion of current information system implementations. As companies continue to move towards a diverse, growing set of Commercial Off the Shelf (COTS) applications to fulfill their information technology needs, the need to integrate data between them continues to increase. In addition, these diverse application portfolios are becoming more geographically dispersed as more software is provided using the Software as a Service (SaaS) model, and companies continue the pattern of moving their internal data centers to cloud-based computing. As the growth of data integration activities continues, several prominent data integration patterns have emerged, and commercial software packages have been created that covers each of the patterns below: 1. Bulk and/or batch data extraction and delivery (ETL, ELT, etc.); 2. Messaging / Message-oriented data movement; 3. Granular, low-latency data capture and propagation (data synchronization). As the data integration landscape within an organization, and between organizations, becomes larger and more complex, opportunities exist to streamline aspects of the data integrating process not covered by current toolsets including: 1. Extensibility by third parties. Many COTS integration toolsets today are difficult if not impossible to extend by third parties; 2. Capabilities to handle different types of structured data from relational to hierarchical to graph models; 3. Enhanced modeling capabilities through use of data visualization and modeling techniques and tools; 4. Capabilities for automated unit testing of integrations; 5. A unified toolset that covers all three patterns, allowing an enterprise to implement the pattern that best suites business needs for the specific scenario; 6. A Web-based toolset that allows configuration, management and deployment via Web-based technologies allowing geographical indifference for application deployment and integration. While discussing these challenges with a large Fortune 500 client, they expressed the need for an enhanced data integration toolset that would allow them to accomplish such tasks. Given this request, the Object Process Methodology (OPM) and the Opcat toolset were used to begin design of a data integration toolset that could fulfill these needs. As part of this design process, lessons learned covering both the use of OPM in software design projects as well as enhancement requests for the Opcat toolset were documented.

Full textAbstract:
Opérations particulièrement complexes, les offres publiques d'acquisition ne cessent de faire parler d'elles, plus particulièrement lorsqu'elles présentent un caractère hostile pour la société visée. De nombreux efforts législatifs ont été mis en œuvre en vue d'encadrer les OPA et de lutter contre les prises de contrôle rampantes. L'analyse du droit positif permet de mettre en lumière ces différents efforts ainsi que leur mise en œuvre à travers diverses techniques par les sociétés visées. Ces dernières ont par ailleurs développé un certain nombre de mécanismes de défense anti-OPA particulièrement efficaces, mais se révélant le plus souvent insuffisants face à l'ingéniosité dont peut faire preuve l'initiateur. Le droit positif montre ainsi ses limites face à des pratiques qui ne cessent d'évoluer. L'analyse prospective du droit anti-OPA permet d'observer les nouvelles mutations que subit le droit positif au regard des nouveaux enjeux économiques. Elle permet également d'envisager de nouveaux modes d'appréhension des OPA hostiles. Il est ainsi possible d'observer que le gouvernement d'entreprise prend une place considérable dans la vie des sociétés cotées. De même, la montée en puissance de la régulation et l'interventionnisme de l’État sont de plus en plus marqués ; et les salariés s'impliquent de plus en plus dans la gestion de l'entreprise. L'ensemble de ces paramètres marquent un glissement progressif vers une réorganisation du mode de fonctionnement des sociétés, ce qui a amené au développement du soft law, un droit à la frontière du droit positif et des pratiques des sociétés. Le soft law constitue à ce titre une approche inédite des OPA hostiles, dont l'analyse permet de cerner les apports liés à la mutation du droit positif et d'envisager l'émergence de nouveaux moyens de défense. Celui-ci doit toutefois demeurer complémentaire au cadre législatif et réglementaire existantNo abstract

The purposes of this dissertation were to determine the constitutional rights of parents to shield their children from exposure to parts of the public school curriculum that the parents find objectionable on religious, moral, or other grounds and to determine the statutory rights of parents to remove, or opt-out, their children from objectionable parts or all of the public school curriculum as set forth in the statutes of the 50 states and the District of Columbia. Many pivotal federal court cases dealing with parent rights and curricular issues, including Mozert v. Hawkins County Board of Education (1987), Vandiver v. Hardin County Board of Education (1987), Brown v. Hot, Sexy, & Safer Productions, Inc. (1995), Leebaert v. Harrington (2003), and Parker v. Hurley (2008) were surveyed using legal research methods. Specific types of curriculum opt-outs (e.g., sex education, comprehensive health programs, HIV/AIDS instruction) granted by each state were ascertained. States' statutes and regulations were categorized as non-existent, restrictive, or permissive based on the scope and breadth of each state's curriculum opt-out statute or regulation. A long list of federal court rulings have provided public schools the right to teach what school boards and administrators determine is appropriate. Parents did not have any constitutional right to opt their children out of public school curriculum. Many states' legislatures have granted parents a statutory right to opt their children out of certain parts of school curricula. In this study, 7 states had non-existent statutes or regulations, 18 states had restrictive statutes or regulations, and 26 states had permissive statutes or regulations.

Det som ansågs intressant att testa var hur dessa verktyg hanterade de rapporter som skapades och samlades in, om det slutgiltiga resultatet från detta skulle skilja sig åt eller inte. För att testa detta sattes en virtuell testmiljö upp, där Sensu och op5 Monitor rullade parallellt med varandra och övervakade samma system och använde sig utav samma plugin för övervakningen. Experimenten utfördes på två stycken tjänster, BIND9 samt Apache2, i och med att de två pluginen som användes var uppbyggda på olika sätt konstruerades även olika experiment. Under dessa experiment samlades information in om hur de två övervakningsverktygen hanterade de rapporter de fick in, vilket sedan sammanställdes och analyserades. Slutsatsen av det hela var att Sensu och op5 Monitor hanterar sina insamlade rapporter på ett likvärdigt sätt, de rapporterade resultaten blev i samtliga fall detsamma, således fungerade de två övervakningsverktygen på ett jämgott vis.The report describes the work and results of a comparison between Sensu and op5 Monitor, which are both tools used to monitor devices in a network, more commonly known as network monitoring systems. The subject was chosen due to the fact that there is such a wide range of network monitoring systems, and it is constantly expanding. It was considered valuable to compare a newcomer with an older tool that is built with a different mindset. It was considered interesting to test how these tools handled the reports created and collected by them, to see if the final results from this would differ or not. To test this a virtual testing environment was built, where Sensu and op5 Monitor were run in parallel to each other and monitored the same systems and used the same set of plugins. The experiments were conducted on two services, BIND9 and Apache2, since the plugins were constructed in different ways, so were the various experiments. In these experiments information was gathered about how the two monitoring tools handled the reports they received, which was then compiled and analysed. The conclusion of it all was that Sensu and op5 Monitor handles the collected information in a similar manner. The reported results were in all cases the same, thus the two monitoring tools behave in the same fashion.

La première partie de ce travail concerne la théorie des Oscillateurs Paramétriques Optiques (OPO) en régime nanoseconde. On présente tout d'abord des rappels sur les milieux non-linéaires et anisotropes, permettant de caractériser le couplage non-linéaire. Ensuite, les équations paramétriques obtenues par prise en compte ou non de la dispersion des indices et de la divergence du champ électrique sont démontrées. Un état de l'art sur les modèles et sur les techniques d'affinement spectral clôt cette partie. La deuxième partie présente deux schémas numériques d'intégration des équations paramétriques. Le premier, basé sur le principe du " split-step ", consiste à intégrer successivement les équations liées aux effets non-linéaires et à la propagation. Il est possible de tenir compte de la fluorescence paramétrique afin de simuler le démarrage de l'OPO. Le second est basé sur une transformation des équations, permettant ainsi d'intégrer les équations de Schrödinger non-linéaires dérivées par la méthode du point fixe, pour des schémas aux différences finies, avec une discrétisation de type Crank-Nicolson. La troisième partie présente des comparaisons entre les simulations numériques et les réalisations expérimentales d'OPO vérifiant ou non les hypothèses des modèles. Puis, elle introduit le principe (nouveau) d'affinement spectral de sources cohérentes par insertion d'un cristal photoréfractif. Ce principe est appliqué à deux lasers continus, puis deux lasers et un OPO en régime nanoseconde. En régime continu, on observe un affinement du spectre d'émission qui devient monomode, accompagné d'une réduction de la largeur spectrale de la raie d'émission. Concernant le laser impulsionnel, on montre une stabilisation en fréquence d'émission et un affinement de la raie d'émission. Quant aux OPO en régime nanoseconde, on montre un affinement du spectre et un bon accord entre les simulations et les résultats expérimentaux.

HMS Industrial networks is a company that offers communication solutions for automation systems. There exists an abundance of different industrial network technologies and HMS manufactures gateways that translate and allow communication between the different networks.The multiplicity of network technologies introduces problems when it comes to monitoring the processes in an automation system. It is desirable to be able to access the process data through a single network technology and this is what OPC UA is used for. Briefly, OPC UA can be described as an interface for exchange ofprocess data in automation systems. HMS has noticed a rising trend in the interest for OPC UA and therefore wants to investigate the possibility to use OPC UA on their platform, the Anybus X-Gateway. The goal of this thesis has been to port an OPC UA stack, provided by the OPCfoundation, to the HMS operating system running on an Anybus X-Gateway. The port has been successful and has been verified by unit tests and a test application. Thus, a first step towards a complete OPC UA product has been taken. Further, the thesis presents a theoretical summary about real-time operating systems to explain their function and usage.

Full textAbstract:
Denna uppsats är en jämförelse mellan den verksamhet som Statens Informationsstyrelse (SIS) bedrev under andra världskriget och den verksamhet som idag bedrivs inom ramen för Informationsoperationer (Info Ops). Uppsatsen syftar till att undersöka om likheterna mellan SIS och Info Ops har en koppling till konfliktens (krigets) natur.
Huvudfrågorna i uppsatsen är:
- Vilka likheter finns mellan den statliga informationsverksamheten som bedrevs av Statens Informationsstyrelse under andra världskriget och den verksamhet som idag bedrivs inom ramen för informationsoperationer?
- Kan likheterna kopplas till konfliktens (krigets) natur och i så fall hur?
För att besvara mina frågor har jag använt mig av följande tillvägagångssätt:
För min inledande del av uppsatsen har jag valt Deskription. Metodiken jag använt är arkiv- och litteraturstudier, vilket vanligen och även i mitt fall föregåtts av en litteratursökning. För den avslutande delen av uppsatsen har jag använt mig av komparation i syfte att finna likheter mellan SIS och Info Ops. För min slutledning har jag använt mig av deduktion.
Det centrala i likheterna mellan SIS och Info Ops är att båda använde/använder data och information för att påverka ett agerande hos människor. Genom att påverka agerandet hos människorna i konflikten (kriget), kan man påverka utgången av konflikten (kriget).

Full textAbstract:
A major Norwegian co-operative faces major challenges in regards to increased competition and a changing market situation. To which extent will the climate for innovation in the company define the employee’s ability and will to change? And, how will management focus on innovation influence employee behavior?
The result of the case study shows that the company has no clear focus on innovation or strategy to build an innovation climate.
The study is of general interest as it underlines theories by Kaufmann & Kaufmann (2003), Ekvall (1996, 1997) og Gjelsvik (2004), as well as the need for top management involvement and crystal clear communication in regards to building an innovative organization.

Dunnett, K. "Non-equilibrium phase transition to the polariton OPO regime." Thesis, University College London (University of London), 2016. http://discovery.ucl.ac.uk/1502096/.
Full textAbstract:
Exciton-polaritons are the quasi-particles that form when cavity photons couple strongly to quantum well excitons in semiconductor microcavities. When a pump laser is applied near the point of inflection of the lower polariton dispersion, a phase transition to the polariton optical parametric oscillator regime where two additional, `signal' and `idler', modes with macroscopic occupation appear can occur. The steady state of the non-equilibrium polariton system is maintained by continuous pumping and the Keldysh functional integral approach is used to study the phase transition. Despite its highly non-equilibrium nature, an effective chemical potential is identified and the phase transition occurs when the effective chemical potential crosses the normal modes. The Keldysh formalism also gives access to the occupations of the modes and experimentally observable properties such as the incoherent luminescence and absorption spectra are calculated. One of the key properties of the signal mode is that it occurs near the minimum of the lower polariton dispersion with zero momentum. To calculate the mean field occupation of the three mode optical parametric oscillator regime analytically, the signal momentum has to be chosen explicitly. A simple method to determine the signal momentum by using linear response analysis for any system parameters is proposed and the predictions compared with numerical integration of the complex Gross-Pitaevskii equations describing the system. At weak pump strengths, the signal momentum is found best by the linear response analysis of the three mode description, while at higher pumping, a linear response analysis of the single pump mode gives best agreement with the numerical simulations.

Apresentamos um estudo de sistemas fotométricos no infravermelho próximo, com especial atenção ao sistema fotométrico da Câmara Infravermelho (CamIV) do PRONEX/IAG- USP. Utilizamos as melhores estimativas das características do sítio do Observatório do Pico dos Dias, no Laboratório Nacional de Astrofísica, e os dados instrumentais provenientes dos fabricantes do detector e dos conjuntos de filtros, para descrever e caracterizar quantitativamente o sistema fotométrico da CamIV por meio da fotometria sintética. Apresentamos exemplos de desempenho do uso da câmara, tanto com o conjunto de filtros de banda larga efetuando a fotometria J e H de NGC 6809 e NGC 6751, quanto com os de banda estreita, com a fotometria de estrelas padrão. Para este último conjunto de filtros apresentamos um método de correlação entre o valor da magnitude na banda larga K e o valor da magnitude em banda estreita. Esta dissertação está assim organizada: na Introdução descrevemos como caracterizar um sistema fotométrico, especialmente no infravermelho próximo. No capítulo dois apresentamos uma descrição da câmara propriamente dita, bem como dos seus principais componentes ópticos. No capítulo três descrevemos o método da fotometria sintética e suas possíveis aplicações. O capítulo quatro destina-se a mostrar o comportamento da CamIV em uso no modo câmara direto, tanto com o conjunto de filtros largos, quanto os estreitos e apresentar o estudo da correlação entre a banda K e os filtros estreitos. No último capítulo discutimos as possibilidades de uso da câmara num contexto geral.We present a photometric study of near infrared photometric systems, paying special attention to the PRONEX/IAG-USP Near Infrared Camera (CamIV) photometric system. From the best estimates for the characteristics of the Pico dos Dias Observatory, at Laboratório Nacional de Astrofísica (OPD/LNA), as well as the manufacturers instrumental data for both the filter sets and detector, we used the synthetic photometry method to describe and characterize the CamIV's photometric system. We show the camera's performance, by using the NGC 6809 and NGC 6751 J and H photometry. We used the narrow band filter set for photometry of standard stars in order to present a statistical correlation between the K broad band magnitudes and the narrow band magnitudes. The dissertation is organized as follows: in the Introduction, we describe how to characterize a photometric system, specially a near infrared photometric system. In Chapter two we present the camera and the major optics characteristics details. In Chapter three we describe the synthetic photometry method and its usefullness. Chapter four shows the camera behaviour with the use of both the broad band filter set, and the narrow baud filter sct and prcscnts the relationship between the narrow band filter set and the catalogued K magnitude for some standard stars. In the last Chapter we discuss the possibilites of further usage of the camera.

Full textAbstract:
High-stakes testing has grown in scope and impact in recent years, as accountability decisions regarding funding, school sanctions, and teacher evaluations often depend on standardized test results. The shift toward more stringent and punitive testing mandates has not gone unchallenged however, as pockets of resistance have emerged among teachers, parents, and scholars, and a growing "opt-out" movement has picked up steam nationwide. Teachers in particular have played a critical role in resistance to high-stakes testing, even while adhering to these same policies in their professional roles. This study examines resistance to standardized testing via the 'opt-out' movement organizing process. I specifically look at teachers' participation in organizing and resistance, and how positions as teachers and sometimes parents influence their participation. I frame the project with a post-structuralism lens, utilizing the Deleuzoguattarian concept of the rhizome to illustrate the complex and connected nature of teachers' involvement in this social movement.

The aim and purpose of this thesis was to understand how different types of museums use project management in capital projects and whether existing project management theory and practice is fit for museums. There is an opportunity to learn and build on existing knowledge of museum, organisation, and project management theory and practice by creating a common-goal, flexible-framework approach to Open Project Management (OPM). Semi-structured interviews were carried out with thirteen senior museum staff and thematic analysis was employed to analyse the data, which were part of case studies of museum projects: Ashmolean Museum; Imperial War Museum London; Victoria & Albert Museum; Museum of Oxford; Museum of the Order of St John; and interviews with members of staff from the British Museum, Compton Verney and wider museum profession. I also applied an autoethnographic approach as I included my experiences as a museum project manager (Ashmolean 2007-2014). Several broad themes emerged from the research. First, new ways of organising – the mission of the museum was often the same as the project, which meant that the senior staff referred to the project as ‘change’ in the organisation, rather than something additional. Second, project management which included collaboration of staff inside and outside the organisation was evident, but was applied differently in each type of organisation. Finally, the importance of the external stakeholders, including funders, was important. Although there are many examples of museum capital projects across the UK, the literature and critical analysis of these projects and processes is lacking in comparison to work carried out worldwide by researchers from a range of disciplines. There is an opportunity to bridge the differences and areas between organisation theories, including leadership and motivation, and project management in order to create a more effective and broader approach to managing projects in museum organisations.
