When did the Indus River of South-Central Asia take on its “modern” drainage configuration?
Get PDFFor sedimentary archives to be used as a record of hinterland evolution, the factors affecting the archive must be known. In addition to tectonics, a number of factors, such as changes in climate and paleodrainage, as well as the degree of diagenesis, influence basin sediments. The Indus River delta-fan system of South-Central Asia records a history of Himalayan evolution, and both the onshore and offshore sedimentary repositories have been studied extensively to research orogenesis. However, a number of unknowns remain regarding this system. This paper seeks to elucidate the paleodrainage of the Indus River, in particular when it took on its modern drainage configuration with respect to conjoinment of the main Himalayan (Punjabi) tributary system with the Indus trunk river. We leverage the fact that the Punjabi tributary system has a significantly different provenance signature than the main trunk Indus River, draining mainly the Indian plate. Therefore, after the Punjabi tributary system joined the Indus River, the proportion of Indian plate material in the repositories downstream of the confluence should have been higher than in the upstream repository. We compared bulk Sr-Nd data and detrital zircon U-Pb data from the Cenozoic upstream peripheral foreland basin and downstream Indus delta and Indus Fan repositories. We determined that throughout Neogene times, repositories below the confluence had a higher proportion of material from the Indian plate than those above the confluence. Therefore, we conclude that the Indus River took on its current configuration, with the Punjabi tributary system draining into the Indus trunk river in the Paleogene, early in the history of the orogen. The exact time when the tributary system joined the Indus should correlate with a shift to more Indian plate input in the downstream repositories only. While the upstream repository records no change in Indian plate input from Eocene to Neogene times, a shift to increased material from the Indian plate occurs at the Eocene−Oligocene boundary in the delta, but sometime between 50 Ma and 40 Ma in the fan. Though further work is required to understand the discrepancy between the two downstream repositories, we can conclude that the tributary system joined the Indus trunk river at or before the start of the Oligocene
Schopenhauer's theory of science
No full textBook synopsis: Arthur Schopenhauer (1788-1860) is now recognised as a figure of canonical importance to the history of philosophy. Schopenhauer founded his system on a highly original interpretation of Kant’s philosophy, developing an entirely novel and controversial worldview guided centrally by his striking conception of the human will and of art and beauty. His influence extends to figures as diverse as Fredrich Nietzsche, Ludwig Wittgenstein and Iris Murdoch within philosophy, and Richard Wagner, Thomas Hardy, Sigmund Freud, Thomas Mann, Samuel Beckett and Jorge Luis Borges outside it.
The Schopenhauerian Mind is an outstanding, wide-ranging collection that explores the rich nature of Schopenhauer's ideas, texts, influences, and legacy. Comprising 38 original chapters by an international team of contributors, the volume is organised into five clear parts:
Knowledge and Reality
Aesthetics and the Arts
Ethics, Politics, and Salvation
Before Schopenhauer
After Schopenhauer
The Schopenhauerian Mind covers all the key areas and concepts of Schopenhauer’s philosophy, including fields omitted in previous studies. It is essential reading for students of nineteenth-century philosophy, Continental philosophy and philosophy of art and aesthetics, and also of interest to those in related disciplines such as literature and religion
Mixed methods when researching sensitive topics
No full textThis chapter expands on choices in mixed methods, ranging from qualitative- to quantitative-driven mixed methods research in the context of emotionally loaded and sensitive topics. Dr Sally Cook explains stages within a qualitative mixed methods approach combining Interpretative Phenomenological Analysis (Smith, Psychology and Health 11:261–71, 1996) and Ethnography to explore the meaning survivors of torture ascribe to using a second language in their healing journey. Dr Louise Rolland describes how combining a web survey with interviews enabled her to unpack the initial, quantitative findings regarding multilingual clients’ language use, revealing rich associations between languages, emotions and identity. Professor Dewaele and Dr Costa add a meta-perspective on methodological choices—as earlier supervisors and mentors and based on their well-established authority in the field of multilingual therapy and mixed methods research
The Green 1890s: world ecology in women’s poetry
No full textThis chapter examines 1890s women poets through the lens of ecology. By focusing on three main parameters (countryside, city, and empire), the chapter offers a new landscape of poets and poetries of the 1890s and argues that some of the most advanced ecological thinking of the period appeared in women’s poetry. Starting with Christina Rossetti, the chapter unveils how poets of the 1890s used genres such as the pastoral, realist, and symbolist poetry paradigmatically to produce powerful critiques of agrilogistics, globalization and eco-colonialism at the fin de siècle. Central to the chapter is its focus on polluted environments. Looking at Amy Levy and Alice Meynell, it shows how their poetics of soot and grime argued for green spaces to combat the damaged caused by the coal industry to modern city living. The chapter also analyzes the anticolonial poetics of Katharine Tynan and Sarojini Naidu and their use of autochthonous plants in their fight against the British empire
DRIVE: Dockerfile Rule Mining and Violation Detection
Get PDFA Dockerfile defines a set of instructions to build Docker images, which can then be instantiated to support containerized applications. Recent studies have revealed a considerable amount of quality issues with Dockerfiles. In this article, we propose a novel approach, Dockerfiles Rule mIning and Violation dEtection (DRIVE), to mine implicit rules and detect potential violations of such rules in Dockerfiles. DRIVE first parses Dockerfiles and transforms them to an intermediate representation. It then leverages an efficient sequential pattern mining algorithm to extract potential patterns. With heuristic-based reduction and moderate human intervention, potential rules are identified, which can then be utilized to detect potential violations of Dockerfiles. DRIVE identifies 34 semantic rules and 19 syntactic rules including 9 new semantic rules that have not been reported elsewhere. Extensive experiments on real-world Dockerfiles demonstrate the efficacy of our approach
Whose public, whose goods? Generations of patients and visions of fairness in Ghanaian health
No full textSince Ghana's independence in 1957, the country has seen an ebb and flow of reforms intended to expand and fund state healthcare, informed by diverse notions of affordability and adequate provision. Cycles of attempted health reforms have emerged from disparate political and economic ideologies, themselves a product of broader global histories and specific national experiences. Based on group interviews with people across most administrative regions of Ghana, this paper examines how the formative historical experiences of different generations gives rise to a multiplicity of understandings of what constitutes a ‘fair’ distribution of national health resources. It discusses the forms and contents of arguments that people of different ages raised in both rural and urban settings in the course of the study - with particular reference to the operation of Ghana's current National Health Insurance Scheme, and in light of their perceptions of the justice or injustice of present day healthcare in relation to earlier periods
The Precautionary Principle when project implementation capacity is congestible
Get PDFThe precautionary principle justifies postponing the implementation of development projects to await better information about their environmental impacts. But if implementation capacity is congestible, as is often the case in practical settings, a postponed project may have to vie for implementation priority with projects that arrive later. Limitations of implementation capacity create two risks. First, it may
sometimes not make sense to go back to a postponed project, even if it is later revealed to be a good one. Second, the planner may find it worthwhile to go back to it, but at the expense of undesirable delay of subsequent projects. We consider a planner facing a sequence of projects that vary stochastically in their (1) importance and (2) improvability but knowing that implementation capacity is congestible. The scope for congestion implies a ‘bonus’ for earlier-than-otherwise decisions, in common parlance ‘keeping the desk clear’, which works against the well-understood option value that encourages postponement. The optimal decision rule depends upon the stochastic environment whereby future projects are generated, in ways that are not obvious. The value of the bonus is increasing in the expected importance of future projects but decreasing in their expected improvability.
Higher variability of the importance of projects, in the sense of mean-preserving spread, increases the size of the bonus, but variability in their improvability has a generally ambiguous impact. We characterize the adjusted decision rule and note its implications for the conduct of cost-benefit informed policy
The relationship between universities’ funding portfolios and their knowledge exchange profiles: a dynamic capabilities view
Get PDFThis paper examines how universities’ knowledge exchange (KE) profiles evolve in relation to changes in the composition of their funding sources. Using the dynamic capabilities framework as a conceptual lens, we examine how changes in the share of KE versus research income in a university’s financial portfolio are related to the mix of KE channels it uses and of types of stakeholders it engages with, that is, its KE profile. Relying on an 8-year panel of 110 UK-based universities we show that, universities whose share of KE income is higher relative to others, are associated with a higher degree specialization in both KE channels and stakeholder types. Conversely, universities whose share of blue-sky research income is higher relative to others, are associated with greater diversification in both. Some of these linkages are negatively moderated by higher levels of tangible and intangible resources: universities with greater intangible resources are less responsive to variations in research and KE income shares on KE channel diversity; while universities with higher tangible resources are less responsive to variations in research income share on KE stakeholder diversity
