This paper is a case study on Bradley E. Manning, famous for leaking classified intelligence to media, or in the charge sheet’s words: “knowingly give intelligence to the enemy, through indirect means.” My opinion is that this sort of dilemma is a question of values, how you view the world and, most important of all, human rights and the philosophy of rights. Therefore I decided to sort out the arguments regarding the issue of freedom of speech versus the state’s need for protection. To do this I performed a pro et contra analysis from John Stuart Mill’s On Liberty and Thomas Hobbes’ Leviathan, this building my theory on which I lean my other work upon. Furthermore, I performed a case study on Manning where I compared the charges and the defense with the arguments of Mill and Hobbes. Ergo: I applied my theory on an existing conflict between freedom of speech and the state’s need for protection to see which arguments that are used in the charge against Manning and if one could derive this from the argumentation analysis consistent of Mill and Hobbes.   Words: 11474

Résumé : L’utilisation de chicanes dans les ponceaux de type insertion en polyéthylène de haute densité (PEHD) est devenue une pratique de plus en plus courante afin d’améliorer les conditions hydrauliques pour le passage des poissons. Cependant, on sait peu sur la façon dont les chicanes affectent la capacité hydraulique des ponceaux. Tout d’abord, une étude comparative a été menée afin de déterminer la variation de la vitesse et de la profondeur entre un ponceau en acier ondulé et un ponceau de type insertion en PEHD pour un débit fixe. Il a été constaté que la vitesse augmentera entre 65% et 260% et la profondeur diminuera entre -58% et -27% selon les valeurs de rugosité réelles du ponceau en tôle ondulée et du ponceau en PEHD. Ces résultats justifient des mesures pour améliorer le passage des poissons, comme par exemple l’installation de chicanes. À cette fin, les coefficients de rugosité n de Manning et f de Darcy ont été déterminés expérimentalement pour les chicanes de type déversoir, les chicanes de type fente et les chicanes de type spoiler pour quatre espacements ( λ = 0.6D , 1.2D, 1.8D, 2.4D ) et trois hauteurs ( h = 0.15D, 0.10D, 0.05D), où D est le diamètre nominal du ponceau. La hauteur des chicanes est ressortie comme étant le paramètre géométrique déterminant affectant la rugosité hydraulique. L’espacement se trouve à jouer un rôle secondaire. Un modèle analytique a été développé et analysé afin de déterminer les effets de la réduction de la rugosité (α = n/nf ), la réduction radiale (β = D/Do), la longueur du ponceau (L) et les traitements d’entrée (ke) sur la capacité hydraulique des ponceaux en tôle ondulée après avoir été réhabilités par insertion d’un ponceau en PEHD. Les résultats montrent que de nombreux ponceaux en PEHD peuvent accueillir des configurations de chicanes ayant des valeurs de α se situant entre 0,5 à 0,9 et continuer de respecter la capacité hydraulique requise. Des recommandations de conception pour l’utilisation de chicanes dans des courts et longs ponceaux en PEHD sont discutées. // Abstract :

Approved for public release; distribution in unlimited. / The Pentagon is planning to gradually increase the Navy's SEAL force over the next several years to meet increasing global demands. The move was authorized by the Office of the Secretary of Defense (OSD) in a program decision memorandum (PDM) in December 2002. The PDM, which directed the growth of Special Operations Forces across the board, called on the Navy to bring the equivalent of two new SEAL Teams to the force between FY-06 and FY-08. Even though funding has been allotted to this task, there may not be enough manpower to fill these slots. Training issues coupled with retention issues have brought the growth process to a standstill. The purpose of this thesis is to identify which major variables and/or combinations of small variables need to be changed in order to increase NSW enlisted SEAL manning. The three major areas that will be looked at are recruitment, training, and retention. The focus will be to determine where NSW can do better at managing personnel in these areas. The end product will be a detailed analysis that will offer suggestions for program changes that can be implemented to increase NSW forces while raising the quality of operators at the same time. / Lieutenant Commander, United States Navy / Lieutenant, United States Navy

Arbetets syfte var att undersöka intentionen och förväntade effekter av den nya sjöarbetskonventionen som nu ska implementeras vad gäller bemanningsnivåer och vilotider på svenska fartyg. Genom att först genomföra en litteraturstudie lades grunden för arbetet. Med anledning av att konventionen inte var implementerad genomfördes en kvalitativ intervjustudie mot tre sakkunniga representanter från svensk sjöfartsnäring för att utreda vad konventionens verkliga intention var. Därefter genomfördes en kvalitativ intervjustudie mot fyra aktörer i den svenska sjöfartsnäringen för att utreda vad dessa förväntade sig för effekter av konventionen, gällande bemanningsnivåer och vilotider. Resultatet av undersökningarna visade på att konventionens intention är att höja den internationella standarden vad gäller just bemanningsnivåer och vilotider till en nivå som liknar den svenska relativt höga nivån. Vad gäller förväntade effekter av konventionen tror de svenska aktörerna att den svenska sjöfartsbranschen kommer att se ganska små förändringar om några alls. / The purpose of this thesis was to examine the intention and expected outcome of the new Maritime Labour Convention 2006 (MLC 2006) regarding the regulations of manning levels and hours of rest on Swedish vessels. Firstly, a thorough literature review was conducted to create a sound foundation for the following investigations. Given that the convention was not implemented during the work of this thesis a qualitative interview was carried out on three expert representatives from the Swedish shipping industry. The purpose of this interview was to determine the intention of the convention. After that a qualitative interview was carried through on four stakeholders in the Swedish shipping industry to investigate what their expectations of the convention's outcome was regarding manning levels and hours of rest. The resulting conclusions of theese studies show that the conventions intention is to raise the global standard of manning levels and hours of rest to a level that is similar to the one already used in the Swedish shipping industry. The expected outcome of the convention regarding the Swedish shipping industry was that there will be very little, or no changes at all.

Orientador: César Gustavo da Rocha Lima / Resumo: O Brasil, frente aos acidentes ocorridos em Mariana – MG (2015) e em Brumadinho – MG (2019), tem vivenciado inúmeras discussões no que tange à assuntos regulatórios e à confiabilidade das barragens construídas no país. Neste trabalho, inicialmente, fez-se um breve comparativo entre a legislação brasileira e alguns normativos internacionais (China, Portugal, Estados Unidos e África do Sul) sobre segurança de barragens, observando-se a existência de diferentes aspectos abordados entre eles. A Política Nacional de Segurança de Barragens se demonstrou uma das regulamentações menos rígidas entre as analisadas quanto a pré-requisitos técnicos para sua aplicação, deixando grande parte das barragens de pequeno porte dispensadas do cumprimento de algumas obrigações. Além disto, a legislação federal brasileira foi implementada há menos de uma década, o que implica, atualmente, em uma dificuldade muito grande do empreendedor, dos órgãos fiscalizadores e do governo federal a se adaptarem a possuir esta cultura de segurança de barragens. Diante da interface destas construções com o meio ambiente, faz-se necessário um monitoramento constante das estruturas por uma equipe multidisciplinar e um programa de segurança consistente que vise garantir a integridade do meio ambiente nas áreas de influência das barragens, bem como resguardar o bem-estar e a vida da população situada a jusante. O uso de funções matemáticas e softwares para o mapeamento das áreas sujeitas aos riscos impostos pelas bar...

In this work, it was made a brief comparison between Brazilian legislation and some international regulations (China, Portugal, United States and South Africa) on dam safety, observing the existence of different aspects addressed among them. The National Dams Safety Policy demonstrated one of the less rigid regulations among those analyzed regarding technical prerequisites for their application, leaving most of the small dams exempted from compliance with certain obligations. In addition, Brazilian federal legislation was implemented less than a decade ago, which currently implies a great difficulty for the entrepreneur, the inspection agencies and the federal government to adapt to having this dam safety culture. In view of the interface of these constructions with the environment, it is necessary a constant monitoring of the structures by a multidisciplinary team and a consistent safety program that aims to guarantee the integrity of the environment in the areas of influence of the dams, as well as to protect the well-being and the life of the downstream population. The use of mathematical functions and softwares for the mapping of the areas subject to the risks imposed by the dams is a great advance in the safety aspect of these structures. In this context,...

The purpose of this study is to investigate the managers’ perspective on leadership in relation to the motivation of the employees by an example of a manning and recruitment agencies. This is implemented by framing of two questions; What kind of leadership can be identified by middle managers to motivate their employees? Which motivation factors are relevant to employees based on the perspective of the managers? To answer the question and identify leadership strategies and motivational factors and the relationship in between, we have conducted eight interviews with persons who hold a middle management position. Through a qualitative investigation we have been able to go into depth and had access to these managers reflections, thoughts and experiences. The study is deductive and based on two theories; Two Factor Theory (Herzberg, 1959) and internal and external motivation (Deci & Ryan, 2000). The study also takes into account previous research on motivation and leadership such as adults' motivation for learning and training (Ahl, 2006), the transformative leadership (Guthenberg, 2011), recognition of motivation (Hansen and Hermansson, 2013), and indications of what creates a good workplace (Lindberg and Vineyard, 2012). We have, using empirical data, developed and identified categories based on two themes, leadership and motivation, to answer our question. Empirical evidence shows that the developed categories commitment and presence, leadership coaching, individual and situational leadership, reward, daily work and corporate culture/relationships go hand in hand and are necessary to achieve good leadership to increase motivation. By this we mean that the involvement and presence, coaching, personalised and situational leadership are central to achieve what we have distinguished to be good leadership. While the reward, the daily work and the corporate culture and the relationships within the organisation are essential parameters to get motivated employees based on the manager's approach. We can also see that these two themes are related and interdependent. Based on empirical data, we perceive that the organisation we studied the good leadership is resulting in better conditions for motivated employees.

This thesis details the hydrodynamic research conducted at Delta Marsh as part of the Restoring the Tradition marsh rehabilitation project. Research has indicated that the hydraulic and hydrologic controls on the marsh can have considerable impacts on its ecological function, but the impacts of these controls had not previously been studied. Field hydrography and two-dimensional numerical modelling (using MIKE 21) provided insight into many aspects of the physical behaviour of Delta Marsh. Eighty five percent of the inflow to Delta Marsh from Lake Manitoba passes through Clandeboye Channel, and these discharge signals propagate as far west as Cadham Bay. Inflow to the marsh disperses quickly, and accounts for a small fraction of the water that exits the marsh during subsequent outflow. Thus, Portage Diversion water that enters the marsh through the lake can remain there even if there is a net loss in marsh volume over the season. Wind friction across Lake Manitoba has the greatest impact on short-term fluctuations in marsh volume and on the composition of marsh water, followed by the Portage Diversion and the natural inflows to Lake Manitoba. Expansions to flood diversion infrastructure will considerably impact the composition of Delta Marsh waters. Three methods of wetland discharge estimation were developed and tested. The most promising method was the regressed slope Manning method (RSMM), which estimates two-directional channel discharge as a function of the water surface elevations at both ends of a channel. When used in conjunction with the velocity index method, the RSMM can multiply the amount of reliable discharge data collected per research dollar. Thanks to its simple formulation, the RSMM is likely applicable outside of wetland settings, as well. / February 2016

Hydrological models are used widely and they demand for multiple input variables and observations. One of those variables is Manning’s roughness coefficient. In the current literature the variability of the coefficient poses an unknown uncertainty. This study examines a small river channel located in central Sweden, and aims to determine the variability and uncertainty of the roughness coefficient during diverse vegetation conditions within the channel. During multiple field visits to the location, slope, water level and cross-section examination is performed. With numerical simulation, discharge and roughness coefficients are obtained. With the hydraulic model (HEC-RAS), stage-discharge rating curves are produced and extrapolation is applied to obtain high flows. Manning’s roughness coefficients and their uncertainties are assessed by two different approaches. Determining the coefficient in a simplified sensitivity analysis by using Manning’s equation and calibrating HEC-RAS while applying Mean absolute error (MAE) calculation. The calculated roughness coefficients presents higher range when using Manning’s equation (summer vegetation conditions – 0.2, winter vegetation conditions – 0.095). On the contrary MAE provides values closer to each other (summer – 0.15, winter – 0.11). The obtained results indicate a high variance between summer and winter vegetation conditions, producing 38 cm water level differences during high flows using Manning’s equation and 6 cm difference using the calibration of the model in HEC-RAS. These results confirm that the roughness coefficient cannot be assumed to be constant throughout different seasons as had been assumed widely when applying hydrological modelling. Throughout the study innovative approaches and methods (e.g. back-calculating from Manning’s equation and calibrating HEC-RAS based on observed water levels) are used in order to determine the consequences of ignoring the variability of the roughness coefficient. Due to the study, one can derive that vegetation needs to be considered in having an important impact on the varying roughness coefficient value and it cannot be left as a constant value within hydrological models. / Hydrologiska modeller är vanligt förekommande för bestämning av vattenföringsprognoser, och kräver ett flertal indata variabler och observationer. En av variablerna är Mannings råhetskoefficient, som orsakar en okänd felmarginal i den hydrologiska modellen. Den här studien syftar till att avgöra osäkerheten av felmarginalen samt variationen av Mannings råhetskoefficient. Det görs genom att undersöka en liten bäck i centrala Sverige vid olika vegetationstillstånd. Flera fältundersökningar genomfördes där tvärsnittsmätningar, vattennivå och hydraulisk gradient bestämdes. Från numerisk simulering kan flöde och råhetskoefficienten kalkyleras. Genom den hydrauliska modellen (HEC-RAS) fås ratingkurvor för vattennivå och flöde, där extrapolering görs för de högre flödena. Mannings råhetskoefficient och dess osäkerhet undersöks med två olika tillvägagångssätt. Den första metoden bygger på att använda Mannings ekvation. Den andra metoden bygger på att först genomföra en kalibrering i HEC-RAS och sedan använda kalkylering av medel-absolut-avvikelse, ”Mean absolute error” (MAE). Råhetskoefficienten beräknad med hjälp av Mannings ekvation ger större spridning (sommar – 0.2, vinter – 0.095) än vid användning av MAE beräkning (sommar – 0.15, vinter – 0.11). Resultatet visar en stor skillnad mellan så kallad vinter och sommar vegetation. Skillnaden i vattennivå är 38 cm vid användning av första metoden och 6 cm vid användning av den andra metoden. Resultaten från den här studien visar att råhetskoefficienten inte kan antas vara stabil under olika säsonger, vilket antas vid hydrologisk modellering. Innovativa metoder, så som bak-kalkylering från Mannings ekvation och kalibrering i HEC-RAS baserad på observerade vattennivåer har används för at bestämma utvärdera konsekvenserna av att ignorera variationen av råhetskoefficienten vid modellering. Den här studien visar att variationen av råhetskoefficienten påverkas av vegetationsförhållandet och att koefficienten inte kan antas konstant för korrekt modellering.
