Crossing the Digital Divide: Monism, Dualism and the Reason Collective Action is Critical for Cyber Theory Production

In studying topics in cyber conflict and cyber-security governance, scholars must ask—arguably more so than has been the case with any other emergent research agenda—where the epistemological and ontological value of different methods lies. This article describes the unique, dual methodological challenges inherent in the multifaceted program on global cyber-security and asks how problematic they are for scholarly efforts to construct knowledge about digital dynamics in world affairs. I argue that any answer to this question will vary depending on how one perceives the social science enterprise. While traditional dualistic perspectives on social science imply unique challenges for researcher, a monistic perspective of Weberian objectivity does not. Regardless of one’s perspective, however, the most important steps to be taken at the level of the research program are clearly those focused on constructing the trappings of community. To this end, I outline steps that might be taken to develop a range of community-building and -supporting mechanisms that can simultaneously support a micro-foundational approach to research and expose community elements to one another. Doing this stands to better opportunities for the production of knowledge and direct researchers towards fruitful avenues whilst shortening gaps between the ivory tower and the real world

Resolving Multi-path Interference in Time-of-Flight Imaging via Modulation Frequency Diversity and Sparse Regularization

Time-of-flight (ToF) cameras calculate depth maps by reconstructing phase shifts of amplitude-modulated signals. For broad illumination or transparent objects, reflections from multiple scene points can illuminate a given pixel, giving rise to an erroneous depth map. We report here a sparsity regularized solution that separates K-interfering components using multiple modulation frequency measurements. The method maps ToF imaging to the general framework of spectral estimation theory and has applications in improving depth profiles and exploiting multiple scattering.Comment: 11 Pages, 4 figures, appeared with minor changes in Optics Letter

William Livingston/Uilleam Macdhunleibhe (1808-70): a survey of his poetry and prose

This thesis is a survey of the work in poetry and prose of William Livingston or Uilleam Mac Dhunl`eibhe, the Islay bard (1808-70). The version of his English surname without final `e' has been preferred because it is used in the definitive, 1882 edition of his poems and throughout the text (but not in the title) of the section of his own clan in the Vindication. The first chapter, `Biography and Background', gathers the available information on the poet's life, and attempts to set him in the context of the cultural, social and economic situation of Islay during the century preceding his birth. The second chapter, `The Intellectual Background', investigates Livingston's reading and his knowledge and use of historical and antiquarian texts. His familiarity with the traditionary version of the origins of the Scottish monarchy, elaborated by patriotic historians before the Union, is especially interesting. Chapter Three, `Polemicist and Historian', looks in detail at a work Livingston edited for publication, MacNichol's remarks on Dr Johnson's account of his journey through Gaelic Scotland, before turning to the poet's longest prose work, the Vindication of the Celtic Character. His shorter pamphlets and the incomplete History of Scotland are also examined. The fourth and fifth chapters explore Livingston's attitude to James Macpherson and to the Gaelic version of his Ossian, and attempt to decide to what extent and in what way he was influenced by the earlier poet. Explicit references to Macpherson in the poetry and prose are surveyed before the triangular relationship between Livingston the poet, Macpherson's work, and ballad material of various degrees of genuineness is discussed. The next two chapters offer close readings of the two major battle poems, `Na Lochalannaich an Ile' and `Bl`ar Shunadail', while Chapters Eight and Nine look at the shorter battle poems, ranging from Mons Graupius, in the first century of the Christian era, to the battle at Gruinard Bay on Islay, which took place just before the union of the crowns, and the battles of Alma and Balaclava in the Crimean War. Chapter Ten is devoted to Livingston's poetry of the Clearances. Its two main focuses are `Cuimhneachan Bhraid-Alba' and `Fios thun a' Bh`aird', and the thesis ends with a close reading of this, perhaps his most famous poem

Measuring sustained attention after traumatic brain injury: Differences in key findings from the sustained attention to response task (SART)

Clinical reports after traumatic brain injury (TBI) suggest frequent difficulties with sustained attention, but their objective measurement has proved difficult. In 1997, Robertson and colleagues reported on a new sustained attention assessment tool, the sustained attention to response task (SART). Individuals with TBI were reported to produce more errors of commission on the SART than control participants, and both groups showed a relationship between SART errors and everyday lapses of attention as measured by the cognitive failures questionnaire (CFQ). Although few direct replications of these findings have been reported, the SART has been used widely as a measure of sustained attention in TBI, in normal controls, and in various other clinical samples. As part of a program of research on attention in TBI, we administered the SART and the CFQ to a sample of 34 survivors of moderate to severe TBI and to 35 control participants. CFQ scores reported by significant others showed clear group differences in everyday lapses of attention. Despite this, group differences in SART errors of commission were small and non-significant, and the correlations between SART errors and CFQ scores were small within both groups. Further analyses excluding participants with invalid score profiles, or restricting the analysis to the first performance of the SART failed to alter the results. These findings suggest that more research is needed to establish the validity of the SART as a measure of sustained attention after TBI, and to determine under what circumstances the original findings hold
