Radiowave scattering and ultra-long-baseline interferometry

Interstellar scattering can irretrievably blur the images of compact radio sources when examined with extremely high resolution. Because of this effect, diffraction limited observations of extragalactic sources with an Earth-Moon baseline will only be possible at frequencies above about 7 GHz, in which case the resolution will be approx. = to or less than 20 microarcsec. Preliminary observations to determine the potential usefulness of such resolving power are discussed. The simplest of these would consist of a search for interstellar scintillations in compact sources at 10 GHz, which would provide an effective resolution about equal to that of an Earth-Moon baseline at this frequency. Also important in this context is the development of very long baseline interferometry in near-Earth orbit, as any ultra high resolution observations, if appropriate, would require intermediate baselines for mapping

The status, rights and treatment of persons with disabilities within customary legal frameworks in Uganda : a study of Mukono District

Little is known about the interaction of customary law and disability rights. This research based on a case study in Uganda offers a window into how a customary legal frameworks can impact the status, rights and treatment of persons with disabilities. Dr Dennison highlights the particular importance of cultural beliefs and attitudes about the capacity and functionality of persons with disabilities in informal legal settings. This is true in the Eastern African context of the Mukono District, in the Central Region of Uganda, but also more widely on the whole African continent. The work concludes by outlining practical change strategies for those seeking to improve the status, rights and treatment of persons with disabilities in settings where customary law plays an influential and effectual role

The status, rights and treatment of persons with disabilities within customary legal frameworks in Uganda: A study of Mukono District

This thesis addresses the question: How do customary legal frameworks impact the status, rights and treatment of persons with disabilities? It is motivated by two underlying premises. First, customary legal frameworks are highly consequential in Sub-Saharan contexts. Second, human impairments are likely to impact status, rights and treatment in customary legal scenarios. In addition, the reality of deep legal pluralism and an anthropologically versed conception of customary law inform the research design. Customary legal content is rightly discerned by researching its substance and application within the lived environment. The researcher gathered input and stories of 63 persons with disabilities and conducted interviews of 23 community members with heightened knowledge of cultural matters in order to discern the experiences of persons with disabilities in non-formal legal contexts. In her semi-autonomous social field approach, Sally Falk Moore considers diverse and layered sources of law when determining the normative legal content in lived contexts. However, this research uncovered little in the way of normative principles specially pertaining to persons with disabilities within lived environments. Instead, legally consequential occurrences take place in customary scenarios that are largely autonomous from formal actors and institutions. The perceived normative substance of formal and customary law can influence the outcome of customary scenarios, but the decision makers' working knowledge of this legal content as it pertains to people with human impairments is limited and disparate. Decision-making family, clan and community members take various factors into consideration when determining rights, status and treatment in customary scenarios. Suppositions about the capacity and functionality of persons with disabilities are particularly influential. Thus, human impairments can be consequential factors in these decisions. This thesis demonstrates that customary scenarios are highly significant forums for establishing customary rights and status in the contexts of marital relations, clan leadership, customary guardianship, customary succession and land rights. Moreover, it indicates that effectual social and legal influences in these scenarios are multi-sourced, multi-layered and dynamic. Finally, the thesis offers practical change strategies suggested by the research for those seeking to improve the status, rights and treatment of persons with disabilities in Mukono District and similar settings

The Resonance of Colonial Era Customary Codes in Contemporary Uganda

Colonial era codifications of customary law – especially those codified in indigenous first languages – have a resilient capacity to form and inform living customary law. In the context of Mukono District, Uganda, modern conceptions of customary law are informed and shaped by colonial era codifications promulgated by the British Protectorate and the Kingdom of Buganda. This research insight offers practical benefits to those seeking to promote access to justice and human rights development in Mukono District. Such benefits speak to the potential vitality and relevance of colonial era customary codifications. Misgivings about the alien influences and exploitative purposes that distorted and corrupted colonial era codes do not warrant disregard of their active legacy within modern customary legal frameworks. The use of receptive research approaches such as those developed and modelled by Sally Falk Moore can help ensure the ongoing influence of colonial era codes are not hidden by contemporary orthodoxies and biases. &nbsp

Comparison of Charge Deposition Profiles in Polymers Irradiated With Monoenergetic Electrons: Pulsed Electroacoustic Measurements and AF-NUMIT3 Modeling

Successful spacecraft design and charging mitigation techniques require precise and accurate knowledge of charge deposition profiles. This paper compares models of charge deposition and transport using a venerable deep dielectric charging code, AF-NUMIT3, with direct measurements of charge profiles via pulsed electroacoustic (PEA) measurements. Eight different simulations were performed for comparison to PEA experiments of samples irradiated by 50 keV or 80 keV monoenergetic electrons in vacuum and at room temperature. Two materials, polyether-ether ketone (PEEK) and polytetrafluoroethylene (PTFE), were chosen for their very low conductivities so that minimal charge migration would occur between irradiation and PEA measurements. PEEK was found to have low acoustic attenuation, while PTFE has high acoustic attenuation through the sample thicknesses of 125 μm and 250 μm for each material. The measurements were directly compared to AF-NUMIT3 simulations to validate aspects of the code and to investigate the importance of various simulation options, as well as to characterize the PEA instrumentation, measurement methods, and signal processing used. The measurement and simulation values for magnitude of charge deposition, penetration depth, and charge deposition spatial profiles are largely in agreement, though spatial and temporal distributions in incident electron flux and effects of radiation induced conductivity (RIC) and delayed RIC during the deposition process complicate the process. This work provides an experimental validation of the AF-NUMIT3 deep dielectric charging code and insight into the accuracy and precision of the PEA method

Legal Ethics and Professionalism

"Legal ethics and professionalism are at the core of legal practice. Advocates must know the requirements of the profession. In addition, being an ethical and professional advocate is about more than following rules. The ethical path a lawyer chooses defines their career and identity. This book is written with both the law student and the legal practitioner in mind. It offers a series of topical chapters addressing matters essential to professional advocacy. Topics range from the advocate-client relationship to judicial ethics. The authors raise cutting edge issues and look forward to future challenges.
