Federal government managers were advised to strengthen internal controls; the law dictates attestation of effective management controls, and the internal control program is used to detect risks. However, managers lacked preparatory training, with training being overlooked given the increased responsibilities. Managers are assigned the programmatic role regardless of the lack of program standards in knowledge, skill, and ability. The research questions addressed change management components, concepts, and core qualifications relative to program readiness. The purpose of this single case study was to identify and explore change management components contributing to the effectiveness of internal controls. The conceptual framework was based on Lewin's change concepts of unfreezing, moving or changing, and refreezing phases with the inverse principle in field theory. Thirteen professionals from the pacific military unit in Hawaii participated in semistructured interviews. Inductive coding was used to thematically analyze the data. The key results of the emerged themes illustrated how: organization skillset was used for linking change components to internal controls, assessment was a tool used for transforming a manager's concept, and experience was essential in leading change core qualifications. Significance of the study was the promotion of stronger measures in preventing fraud, waste, and mismanagement of limited resources. The research results could inspire social change by increasing communication and collaboration to benefit senior leaders, and financial and program managers. The value-added training concepts and leadership innovation, and how managing change relates to internal control could lead to program success thus benefiting all primary stakeholders.

Les techniques de biologie moléculaire ont pris au cours des 20 dernières années une place importante dans le diagnostic direct des pathogènes viraux. Notre travail a porté sur la mise en place et le développement d’une plate-forme de biologie moléculaire, au sein du laboratoire de virologie de l’hôpital de la Timone, pour répondre aux demandes et contraintes du diagnostic en milieu hospitalier. L’organisation de cette plate-forme a nécessité plusieurs étapes : la prévention des risques de contamination, l’aliquotage et le stockage des réactifs, l’automatisation des techniques d’extraction des acides nucléiques, la mise au point de témoins positifs synthétiques et de témoins internes et l’optimisation des protocoles de PCR. Cette approche optimisée du diagnostic moléculaire des infections virales a été appliqué notamment à la détection de la grippe pandémique A/H1N1v dans les laboratoires de routine hospitalière et d’urgence « Point Of Care ». La mise en place de cette plate-forme a fait progresser de manière considérable le diagnostic moléculaire du laboratoire. Elle nous permet actuellement de détecter un grand nombre de pathogènes (>80) et de réaliser des tests dans un format à haut débit (≈40 000 tests/an). Au total, cette plateforme est au coeur de la capacité du laboratoire pour réagir de manière rapide aux évènements d'émergence en mettant en place rapidement des procédures diagnostiques standardisées. Ces techniques ont été transférées à de nombreux autres laboratoires de virologie partenaires nationaux et internationaux. Nous envisageons maintenant son utilisation dans une approche syndromique avec notamment, le développement du diagnostic des virus respiratoires. / Molecular biology techniques have taken an important role in the direct diagnosis of viral pathogens over the last 20 years. Our work focused on establishing and developing a platform for molecular diagnosis in the laboratory of Virology (Timone Hospital) to meet the demands and constraints of diagnosis in hospitals. The organization of this platform required several steps: prevention of contamination risks, aliquoting and storage of reagents, automation techniques of nucleic acid extraction, development of synthetic positive controls and internal controls and optimization of PCR protocols. This optimized approach of the molecular diagnosis of viral infections has particularly been applied to the detection of pandemic influenza A/H1N1v in hospital laboratories for routine and emergency "Point Of Care." The implementation of this platform has significantly improved molecular diagnosis in our laboratory. It currently allows us to detect a large number of pathogens (> 80) and perform tests in a high-throughput (≈ 40,000 tests per year). In total, this platform is at the heart of the laboratory capacity to react quickly to emerging events by rapidly implementing standardized procedures. These techniques have been transferred to many other partners’ laboratories nationally and internationally. We are now considering its use in a syndromic approach including the development of the diagnosis of respiratory viruses.

Syftet med denna studie är att undersöka vilka förändringar börsnoterade företag upplever efter konvertering till IFRS 15. Studiens vetenskapliga metod är kvalitativ forskning där datainsamlingen sker genom intervjuer. Studiens urval består av åtta respondenter från åtta olika börsnoterade företag. De utvalda respondenterna valdes på grund av sina kunskaper om IFRS 15 samt erfarenhet av FRS både före och efter implementeringen av IFRS 15. Vidare består den teoretiska referensramen av fyra organisatoriska förändringar i form av system och rapporteringssystem, interna kontroller, upplysningskrav samt kontraktsutformning. Uppsatsen har även institutionell teori som bas då den förklarar hur institutionella krafter influerar företag till att utföra förändringar. I studiens teori nämndes arbetsuppgifter som en indirekt påverkan på företag. I studien togs därmed med arbetsuppgifter som en femte förändring i den empiriska datainsamlingen. Resultat och slutsatser påvisar att majoriteten av respondenterna upplever förändring och merarbete gällande nya upplysningskrav enligt IFRS 15. Dessutom visar studien att en minoritet av respondenterna infört nya system samt interna kontroller efter konverteringen till IFRS 15. Med anledning av att samtliga företags nuvarande system och policys överensstämmer med IFRS 15, har majoriteten av respondenter upplevt att kontraktsutformning samt arbetsuppgifter förblivit oförändrade i samband med övergången till IFRS 15. / The purpose of this study is to investigate what changes listed companies experience after a transition to IFRS 15. The study's scientific method is of qualitative research where the data collection is made through interviews. The study's selection consists of eight respondents from eight different listed companies. The selected respondents were chosen because of their knowledge of IFRS 15 and experience with IFRS both before and after the implementation of IFRS 15. Furthermore, the theoretical reference framework consists of four organizational changes as in systems and reporting systems, internal controls, disclosure requirements and contract design. The study has also chosen institutional theory as the basis because it explains how institutional forces influence companies to make changes. In the theory of the study, work tasks were mentioned as an indirect impact on companies. The study therefore chose to include work tasks as a fifth change in the empirical data collection. Results and conclusions show that the majority of respondent’s experience change and additional work regarding new disclosure requirements according to IFRS 15. In addition, the study shows that a minority of respondents introduced new systems and internal controls after the transition to IFRS 15. Due to that all the companies' current systems and policies are consistent with IFRS 15, the majority of respondents’ have experienced that contract design and work tasks have remained unchanged after the transition to IFRS 15.

This dissertation focused on the IRIS design since this will likely be one of the designs of choice for future deployment in the U.S and developing countries. With a net 335 MWe output IRIS novel design falls in the “medium” size category and it is a potential candidate for the so called modular reactors, which may be appropriate for base load electricity generation, especially in regions with smaller electricity grids, but especially well suited for more specialized non-electrical energy applications such as district heating and process steam for desalination. The first objective of this dissertation is to evaluate and quantify the performance of a Nuclear Power Plant (NPP) comprised of two IRIS reactor modules operating simultaneously with a common steam header, which in turn is connected to a single turbine, resulting in a steam-mixing control problem with respect to “load-following” scenarios, such as varying load during the day or reduced consumption during the weekend. To solve this problem a single-module IRIS SIMULINK model previously developed by another researcher is modified to include a second module and was used to quantify the responses from both modules. In order to develop research related to instrumentation and control, and equipment and sensor monitoring, the second objective is to build a two-tank multivariate loop in the Nuclear Engineering Department at the University of Tennessee. This loop provides the framework necessary to investigate and test control strategies and fault detection in sensors, equipment and actuators. The third objective is to experimentally develop and demonstrate a fault-tolerant control strategy using this loop. Using six correlated variables in a single-tank configuration, five inferential models and one Auto-Associative Kernel Regression (AAKR) model were developed to detect faults in process sensors. Once detected the faulty measurements were successfully substituted with prediction values, which would provide the necessary flexibility and time to find the source of discrepancy and resolve it, such as in an operating power plant. Finally, using the same empirical models, an actuator failure was simulated and once detected the control was automatically transferred and reconfigured from one tank to another, providing survivability to the system.

Model reduction is a powerful and ubiquitous tool used to reduce the complexity of a dynamical system while preserving the input-output behavior. It has been applied throughout many different disciplines, including controls, fluid and structural dynamics. Model reduction via proper orthogonal decomposition (POD) is utilized for of control of partial differential equations. In this thesis, the analytical expressions of POD modes are derived for the heat equation. The autocorrelation function of the latter is viewed as the kernel of a self adjoint compact operator, and the POD modes and corresponding eigenvalues are computed by solving homogeneous integral equations of the second kind. The computed POD modes are compared to the modes obtained from snapshots for both the one-dimensional and two-dimensional heat equation. Boundary feedback control is obtained through reduced-order POD models of the heat equation and the effectiveness of reduced-order control is compared to the full-order control. Moreover, the explicit computation of the POD modes and eigenvalues are shown to allow the computation of different n-widths approximations for the heat equation, including the linear, Kolmogorov, Gelfand, and Bernstein n-widths.

This study explores the variable speed operation and shift response of a prototype of a two speed single path CVT rotorcraft driveline system. Here a Comprehensive Variable Speed Rotorcraft Propulsion system Modeling (CVSRPM) tool is developed and utilized to simulate the drive system dynamics in steady forward speed condition. This investigation attempts to build upon previous variable speed rotorcraft propulsion studies by: 1) Including fully nonlinear first principles based transient gas-turbine engine model 2) Including shaft flexibility 3) Incorporating a basic flight dynamics model to account for interactions with the flight control system. Through exploring the interactions between the various subsystems, this analysis provides important insight into the continuing development of variable speed rotorcraft propulsion systems.

Sweden has an obligation to report child abuse suspicions to Social Services. According to Socialtjänstlagen (swedish constitution) 1 § Chapter 14, all employees in agencies affecting children, such as schools, have a responsibility to report their suspicions. Research shows that many abuses are not reported. The consequence of this is that Social Services does not hear about all cases of abused and harmed children. One profession where reporting is mandated is school counselors. The school counselor has a particular status in the educational community and meets many maltreated children, and children who injure themselves through their own behavior. The purpose of our study was to describe the circumstances that school counselors believe may affect their tendency to report. Using qualitative methods, we had eight interviews with school counselors from different municipalities who work with students of different ages, and who have different experiences within their profession. The result was related to the theoretical frames of the written composition by Stephen Webb’s (2006), The Rationality of Regulation and the Sociological Concepts of Formal and Informal Social Controls (Israel, 1968). Our study shows that all school counselors knew that a report had to be submitted even at the slightest suspicion, although several of them said that they in some cases avoided to report. The reasons for this, which all according to our interpretation means that the regulation and the social control of maltreated children does not always work, could have to do with the cooperation and response from the social services, or that they assumed that the involvement with the social services would not benefit the child. It could also be that the student’s situation was not serious enough to report, or that they wanted more information about the situation before reporting. Another reason could be that they assumed that there are better ways to sort out the students’ concerns within the school or other agencies, especially if it regards an older student. The study also shows that the school counselors felt there was a risk in losing the students trust when reporting their suspicions.

The University of Waterloo Alternative Fuels Team’s participation in EcoCAR: The Next Challenge provided an unparalleled opportunity to execute advanced vehicle technology research with hands on learning and industry leading mentoring from practicing engineers in the automotive industry. This thesis investigates the optimization of the hybrid operating strategy on board the EcoCAR development vehicle. This investigation provides the framework to investigate the pros and cons of different hybrid control strategies, develop the model based design process for controls development in a student team environment and take the learning of this research and apply them to a mule development vehicle. A primary controls development model was created to simulate software controls before releasing to the vehicle level and served as a tool to evaluate and compare control strategies. The optimization routine was not directly compatible with this model and so a compromise was made to develop a simplified vehicle model in the MATLAB environment that would be useful for observing trends but realizing that the accuracy of the results may not be totally consistent with the real world vehicle. These optimization results were then used to create a new control strategy that was simulated in the original vehicle development model. This new control strategy exhibited a 15% gain in fuel economy over the best case from the literature during an Urban Dynamometer Driving Schedule (UDDS) drive cycle. Recommendations for future work include adding charge depletion operation to the simulation test cases and improving the accuracy of the optimization model by removing the simplifications that contributed to faster simulation time. This research has also illustrated the wide variability of drive cycles from the mildly aggressive UDDS cycle having 5 kilowatts average propulsion power to the very aggressive US06 cycle having 19 kilowatts average propulsion power and their impact on the efficiency of a particular control strategy. Understanding how to adapt or tune software for particular drive cycle or driver behaviour may lead to an interesting area of research.
