The optics and photonics development is currently driven towards nanometer scales. However, diffraction imposes challenges for this development because it prevents confinement of light below a physical limit, commonly known as the diffraction limit. Several implications of the diffraction limit include that conventional optical microscopes are unable to resolve objects smaller than 250nm, and photonic circuits have a physical dimension on the order of the wavelength. Metals at optical frequencies display collective electron oscillations when excited by photon energy, giving rise to the surface plasmon modes with subdiffractional modal profile at metal-dielectric interfaces. Therefore, metallo-dielectric structures are promising candidates for alleviating the obstacles due to diffraction. This thesis investigates a particular branch of plasmonic structures, namely plasmonic antennas, for the purpose of optical imaging and sensing applications. Plasmonic antennas are known for their ability of dramatic near-field enhancement, as well as effective coupling of free-space radiation with localized energy. Such properties are demonstrated in this thesis through two particular applications. The first one is to utilize the interference of evanescent waves from an array of antennas to achieve near-field subdiffraction focusing, also known as superfocusing, in both one and two dimensions. Such designs could alleviate the tradeoffs in the current near-field scanning optical microscopy by improving the signal throughput and extending the imaging distance. The second application is to achieve more efficient radiation from single-emitters through coupling to a highly directive leaky-wave antenna. In this case, the leaky-wave antenna demonstrates the ability of enhancing the directivity over a very wide spectrum.

In exploring Tiv and Inuit conflict resolution processes, this study found astute principles in operation. The case study groups afforded expanded understandings of human conflict and conflict resolution based upon time tested cultural approaches. These approaches recommend people oriented models to problem solving, which reach beyond problems to transform the parties involved in the process. These are purported to be durable means to deal with issues; for if people change positively, their issues are easily transformed as well. Indigenous ideologies of conflict also challenge conventional processes of legal adjudication and offer traditional wisdoms with potential to assist in mediating seemingly intractable and deadly conflicts. Although separated by thousands of miles, Tiv of the Benue Valley in present day Nigeria and Inuit of Northern Canada provide fascinating case examples in their converging cultural ideologies. They have key conditions in common; the use of creative conflict resolution tools and methods within quasi egalitarian social arrangements. Also, while faced with rapidly changing social dynamics, both groups have tenaciously held unto their original cultural tenets for conflict resolution and peacemaking. Their differences are just as compelling; of immediate significance is population size. Inuit are much fewer in number, less than a hundred thousand people and live in smaller settlements. The Tiv group is larger, almost three million people who live in larger urban or rural settings. Inuit brave extremely cold weather conditions for much of the year while Tiv find ways to survive extremely hot weather conditions. Each has shared worthy wisdom for resolving conflicts facing their peoples at various levels; interpersonal conflicts, intergroup violence, youth violence and aggression, as well as cultural principles to prevent social vices such as suicides, murder and generally deteriorating social competencies. This qualitative inquiry integrates narrative, ethnographic and indigenous methodologies to investigate Tiv and Inuit use of original conflict resolution and peacemaking processes usually accomplished through creative means such as storytelling, dance, songs, games, ritual, proverbs, sayings and community processes. Specific attention is paid to the strengths and challenges faced in the practice and application of indigenous theories of conflict and peace. Findings are then incorporated into the contemporary discourse on conflict, peace, justice, conflict resolution and peacemaking. The study is informed by theories of decolonization, indigenous legal theory, post colonialism and conflict transformation.

An enhanced attitudes methodology within the framework of the Graph Model for Conflict Resolution (GMCR) is developed and applied to a range of environmental disputes, including a sustainable development conflict, an international climate change negotiation and a selection of brownfield conflicts over a proposed transfer of ownership. GMCR and the attitudes framework are first defined and then applied to a possible Sino-American climate negotiation over reductions in greenhouse gas emissions. A formal relationship between the attitudes framework and relative preferences is defined and associated mathematical theorems, which relate the moves and solution concepts used in both types of analysis, are proven. Significant extensions of the attitudes methodology are devised in the thesis. The first, dominating attitudes is a methodology by which the importance of a decision maker’s (DM’s) attitudes can be used to evaluate the strength of a given state stability. The second, COalitions and ATtitudes (COAT), is an expansion of both the attitudes and coalitions frameworks which allows one to analyze the impact of attitudes within a collaborative decision making setting. Finally, the matrix form of attitudes, is a mathematical methodology which allows complicated solution concepts to be executed using matrix operations and thus make attitudes more adaptable to a coding environment. When applied to environmental management conflicts, these innovative expansions of the attitudes framework illustrate the importance of cooperation and diplomacy in environmental conflict resolution.

In this thesis, we propose a new method for content-aware resizing of videos in real- time. Our approach consists of two steps. First, we compute a set of non-salient pixels in linear time which, when being removed or duplicated, do not alter the general appearance of the video. This is an extension of Avidan and Shamir's [3] greedy seam-carving approach to video. Second, we generate a new representation of the video, so called multi-view videos that allow us to resize the video in real-time, i.e. while being watched. This representation can be computed very effciently, the complexity is linear in the number of frames and linear in the number of pixels in a video. Our technique works on a broad variety of videos and is computationally inexpensive enough to be executed by a vast range of devices. We compare our technique to our own implementation of a current state-of-the-art approach and show several convincing results obtained by our technique.

<p>The main aim of the research was to determine the viability of retaliation as a trade remedy under the Dispute Settlement Understanding. It was to establish whether retaliation as a remedy is beneficial to the entire WTO membership and system. The specific objectives were: to examine the feasibility of damages as an alternative remedy to retaliation / to determine whether there is a need to revise the Dispute Settlement Understanding, for it to adopt a more development friendly approach to dispute resolution / to make recommendations regarding the improvement of the Dispute Settlement Understanding.</p>

<p>Aims of the research paper is to examine the legal framework&nbsp / of implemantation and enforcement of DSB recommendations and rulings and to investigate the trend of non-compliance with BSD recommendations and rulings where complianant&nbsp / &nbsp / is a developing country.</p>
