The Precipitationshed : Concepts, Methods, and Applications

Human societies are reliant on the functioning of the hydrologic cycle. The atmospheric branch of this cycle, often referred to as moisture recycling in the context of land-to-land exchange, refers to water evaporating, traveling through the atmosphere, and falling out as precipitation. Similar to the surface water cycle that uses the watershed as the unit of analysis, it is also possible to consider a ‘watershed of the sky’ for the atmospheric water cycle. Thus, I explore the precipitationshed - defined as the upwind surface of the Earth that provides evaporation that later falls as precipitation in a specific place. The primary contributions of this dissertation are to (a) introduce the precipitationshed concept, (b) provide a quantitative basis for the study of the precipitationshed, and (c) demonstrate its use in the fields of hydrometeorology, land-use change, social-ecological systems, ecosystem services, and environmental governance. In Paper I, the concept of the precipitationshed is introduced and explored for the first time. The quantification of precipitationshed variability is described in Paper II, and the key finding is that the precipitationsheds for multiple regions are persistent in time and space. Moisture recycling is further described as an ecosystem service in Paper III, to integrate the concept into the existing language of environmental sustainability and management. That is, I identify regions where vegetation more strongly regulates the provision of atmospheric water, as well as the regions that more strongly benefit from this regulation. In Paper IV, the precipitationshed is further explored through the lens of urban reliance on moisture recycling. Using a novel method, I quantify the vulnerability of urban areas to social-ecological changes within their precipitationsheds. In Paper V, I argue that successful moisture recycling governance will require flexible, transboundary institutions that are capable of operating within complex social-ecological systems. I conclude that, in the future, the precipitationshed can be a key tool in addressing the complexity of social-ecological systems. 

Investigations on the Radiation Characteristics of Broadband Strip Loaded Slotted Microstrip Antennas

With the recent progress and rapid increase in mobile terminals, the design of antennas for small mobile terminals is acquiring great importance. In view of this situation, several design concepts are already been addressed by the scientists and engineers. Compactness and efficiency are the major criteria for mobile terminal antennas. The challenging task of the microwave scientists and engineers is to device compact printed radiating systems having broadband behavior, together with good efficiency. Printed antenna technology has received popularity among antenna scientists after the introduction of microstrip antenna in 1970s. The successors in this kind such as printed monopoles and planar inverted F are also equally important. Scientists and Engineers are trying to explore this technology as a viable coast effective solution for forthcoming microwave revolution. The transmission line perspectives of antennas are very interesting. The concept behind any electromagnetic radiator is simple. Any electromagnetic system with a discontinuity is radiating electromagnetic energy. The size, shape and the orientation of the discontinuities controls the radiation characteristics of the system such as radiation pattern, gain, polarization etc. It can be either resonant or non resonant structure.

Sesamoids of the metatarsophalangeal joint of the big toe: a sistematic review

Abstract: The first metatarsal sesamoid bones are not always taken into consideration when making a diagnosis, in pathologies that affect the region of the first metatarsal head. This is due to the insufficient knowledge of all the pathologies that can affect the sesamoids and the relative little incidence that they have. With the increment of sports activities, in particular the running, increasingly affects of the symptoms concerning this region are observed. Methods: A literature search was performed in 5 databases (Medline, PubMed, Scopus, Cochrane Library and BUCEA). The terms included in the search were: sesamoids, anatomy, biomechanics, sesamoids review and sesamoids pathology. In the initial search articles with no more than 10 years, only humans and revision texts are considered. Results: 24 articles were selected and include different pathologies with diagnosis using imaging tests and treatments, both conservative and surgical; as well as aspects from the biomechanics of the metatarsal-sesamoid joint. Conclusion: Sesamoids due of his anatomy, topography and function can be involved in a lot of pathologies; with similar signs and symptoms that can confuse the podiatry when he has to make a correct diagnosis or treatment.

The Undersea World of the Sound Department: the Construction of Sonic Conventions in Sub-aqua Screen Environments

The availability of new underwater cameras and sub-aqua diving gear in the immediate post-war era opened up exciting possibilities for both narrative and documentary filmmakers. While the visual elements of this new world could now be more easily captured on film, the sound elements of the sub-aqua environment remained more elusive. What did, or should, this undersea world sound like? This article examines the use of sound in the sub-aqua scenes of both fictional and documentary films in the 1950s and asks questions about the methods used in the sonification of these worlds. Comparing the operation of underwater sound and human hearing with the production and post-production strategies used by filmmakers, I seek to identify the emergence of a sound convention and its implications for issues of cinematic realism. Central to this convention is the manipulation of sonic frequencies. The sound strategies adopted also raise questions about the malleability of viewer perspective and sound-image relationship in terms of a realist mode of address. Linked to this is the use of sound to enhance audience experience on an affective level. As well as underpinning cinematic realism, these new sound environments offered fresh experiences to audiences seeking new reasons to visit the cinema in an era of widening forms of entertainment.

The Object Animates: Displacement and Humility in the Theatre of Philippe Quesne

This article considers the animating role that objects play in the theatre of Philippe Quesne and Vivarium Studio (France). The conventional role of object animation is often characterised by the performer manipulating objects and scenic material on the stage, asserting a control over the environment they are implicated in. In Quesne's theatre, this relationship is democratised. The theatrical apparatus, both materially and conceptually, is set up to enable the flow of animation to be interchangeable, affording an equal agency to the objects being used much as that of the performers. This theatre of animation is drawn through the framing concepts of displacement and humility. Displacement is considered as a compositional strategy that makes us aware of the volume of the stage space beyond the proscenium frame as a plane of composition. The introduction of large inflatable objects, real cars or large roles of fake snow foreground the objects material presence allows Quesne to play with moments of equilibrium, tipping, excess and absence. Humility is traced as a philosophy of objects that transcends the choice, handling and use of material items in Quesne's work. Simple objects take on a specific vibrancy because of how they give shape to the human participants on stage, animating moments of recognition that allows the human figure, its ethics, emotions and humour, to appear.

From "Rational Utopia" to "Will-to-Utopia". On the "Post-modern" Turn in the Recent Work of Agnes Heller

Agnes Heller recently described her position as 'postmodernist', suggesting a move from a political radical to a politically liberal or 'neoconservative' position. The aim of this paper is to assess the degree to which Heller can still be regarded as a radical political thinker through an evaluation of her work on autonomy, democracy and contingency all of which remain key concepts in her thinking about the political. We find in each case that whilst many of the motifs of her critical Marxist period recur in her recent work, they are losing their oppositional or 'negative' character in the sense that making these motifs operational would require changes to the structure or functioning of liberal-capitalism. Whils remaining in some sense a radical thinker Heller has moved from the advocacy of a 'rational utopia' to a form of theorising which I describe as 'will-to-utopia': radical at the surface yet conservative at the core.

SPINNING NARRATIVES ACROSS POLITICAL DIVIDES: HARNESSING THE CULTURAL POWER OF A STORY WELL-TOLD

This dissertation explores how two American storytellers, considered by many in their to be exemplary in their craft, rely on narrative strategies to communicate to their audiences on divisive political topics in a way that both invokes feelings of pleasure and connection and transcends party identification and ideological divides. Anna Quindlen, through her political columns and op-eds, and Aaron Sorkin, through his television show The West Wing, have won over a politically diverse fan base in spite of the fact that their writing espouses liberal political viewpoints. By telling stories that entertain, first and foremost, Quindlen and Sorkin are able to have a material impact on their audiences on both dry and controversial topics, accomplishing that which 19th Century writer and activist Harriet Farley made her practice: writing in such a way to gain the access necessary to “do good by stealth.” This dissertation will argue that it is their skilled use of storytelling elements, which capitalize on the cultural relationship humans have with storytelling, that enables Quindlen and Sorkin to achieve this. The dissertation asks: How do stories shape the beliefs, perspectives, and cognitive functions of humans? How do stories construct culture and interact with cultural values? What is the media’s role in shaping society? What gives stories their power to unite as a medium? What is the significance of the experience of reading or hearing a well-told story, of how it feels? What are the effects of Quindlen’s and Sorkin’s writing on audience members and the political world at large? What is lost when a simplistic narrative structure is followed? Who is left out and what is overlooked? The literature that informs the answers to these questions will cross over and through several academic disciplines: American Studies, British Cultural Studies, Communication, Folklore, Journalism, Literature, Media Studies, Popular Culture, and Social Psychology. The chapters will also explore scholarship on the subjects of narratology and schema theory.

Detached eddy simulation of unsteady turbulent flows in the draft tube of a bulb turbine

Les aspirateurs de turbines hydrauliques jouent un rôle crucial dans l’extraction de l’énergie disponible. Dans ce projet, les écoulements dans l’aspirateur d’une turbine de basse chute ont été simulés à l’aide de différents modèles de turbulence dont le modèle DDES, un hybride LES/RANS, qui permet de résoudre une partie du spectre turbulent. Déterminer des conditions aux limites pour ce modèle à l’entrée de l’aspirateur est un défi. Des profils d’entrée 1D axisymétriques et 2D instationnaires tenant compte des sillages et vortex induits par les aubes de la roue ont notamment été testés. Une fluctuation artificielle a également été imposée, afin d’imiter la turbulence qui existe juste après la roue. Les simulations ont été effectuées pour deux configurations d’aspirateur du projet BulbT. Pour la deuxième, plusieurs comparaisons avec des données expérimentales ont été faites pour deux conditions d’opération, à charge partielle et dans la zone de baisse rapide du rendement après le point de meilleur rendement. Cela a permis d’évaluer l’efficacité et les lacunes de la modélisation turbulente et des conditions limites à travers leurs effets sur les quantités globales et locales. Les résultats ont montrés que les structures tourbillonnaires et sillages sortant de la roue sont adéquatement résolus par les simulations DDES de l’aspirateur, en appliquant les profils instationnaires bidimensionnels et un schéma de faible dissipation pour le terme convectif. En outre, les effets de la turbulence artificielle à l’entrée de l’aspirateur ont été explorés à l’aide de l’estimation de l’intermittence du décollement, de corrélations en deux points, du spectre d’énergie et du concept de structures cohérentes lagrangiennes. Ces analyses ont montré que les détails de la dynamique de l’écoulement et de la séparation sont modifiés, ainsi que les patrons des lignes de transport à divers endroits de l’aspirateur. Cependant, les quantités globales comme le coefficient de récupération de l’aspirateur ne sont pas influencées par ces spécificités locales.

'Yes, the century is an ashen sun': poem and subject in the philosophy of Alain Badiou

This thesis examines the relation between philosophy, the poem and the subject in the mature philosophy of Alain Badiou. It investigates Badiou’s decisive contribution to these questions primarily by means of comparison, especially to Martin Heidegger, Philippe Lacoue-Labarthe and Theodor Adorno, as well as by analysing Badiou’s readings of poems and prose by Paul Celan and Samuel Beckett respectively as sites of potential dialogue with his immediate predecessors. The thesis stresses the importance of French philosophy’s German heritage, emphasising not only Badiou’s radical departure from Heidegger and his legacy, but also the former’s wholesale rejection of philosophies that would, in the wake of twentieth-century violence and beyond, proclaim their own end or completion. The thesis argues Badiou’s innovative readings of Celan and Beckett to be crucial to understanding this endeavour: for Badiou, both writers use the poem to affirm novel conceptions of subjectivity capable of transcending the historical conditions of their presentation. The title quotation from Badiou’s The Century, ‘Yes, the century is an ashen sun’, anticipates both the affirmative nature of these subjective figures, and their presience, beyond the bounds of a twentieth-century ‘ashen sun’ pervaded by melancholy, for the ‘new suns’ of the twenty-first. The thesis is in four chapters. The first chapter unfolds the central concepts of Badiou’s departure from Heidegger using Paul Celan’s poems to focus the enquiry. It is guided by two of Badiou’s most condensed declarations about the poem, that, firstly, ‘the modern poem harbours a central silence’, and secondly, that ‘Celan completes Heidegger’. The second chapter exposes the political implications of Heidegger’s writings on Friedrich Hölderlin and the role of the subject therein, offering at its close some thoughts about what Badiou calls, following Philippe Lacoue-Labarthe, the poem’s ‘becoming-prose’. It concludes by drawing the poem and politics into relation by way of the philosophical category of the subject. The third chapter reads Badiou’s concept of ‘anabasis’ against Heidegger’s ‘homecoming’ in order to think the possibility of a collective political subject’s formation in the wake of Auschwitz. The final chapter examines the imbrication of the Two of love and the ‘latent poem’ in Badiou’s reading of Samuel Beckett’s late prose, contrasting this ‘affirmative’ reading of Beckett to Theodor Adorno’s earlier emphases on negation. Following its investigations of subjectivity, poem and prose throughout, the thesis concludes by returning to the title quotation in order to unfold the particular relations between subject, affirmation and negation Badiou’s philosophy enacts, and to offer further routes forward for research regarding Badiou’s philosophy and aesthetic figuration.

Every nation under heaven: the importance of the biblical concept of nations for contemporary mission practice

Is there a concept of nationhood in the Bible that can provide us with a framework for cross-cultural Christian mission? This thesis argues that current evangelical missiology has accepted too willingly the categories of the secular Enlightenment understanding of ethnicity and nationhood, and that it needs to rethink its understanding of nations from a biblical standpoint. While the pressures of globalisation are seen by some as rapidly eclipsing the nation-state, this thesis will argue that we need to move beyond the narrower secular categories of citizenship, political power and the boundaries of the state to recover a more biblical understanding of nationhood. By reference to Genesis 10-11, Acts 2:1-11 and those passages in the Book of Revelation that discuss the destiny of the nations, it will show that the biblical understanding of nations includes deeper ideas of shared history, culture and language as the essential components of nationhood. It will explain how nations are part of the created order, and explore the impact of the Babel narrative on our understanding of nations in relation to God. It will demonstrate that Pentecost did not reverse the curse of Babel, but served rather to honour the dignity and value of nations and their languages. It will also argue that nations have a destiny in the New Creation according to the Book of Revelation. This biblical concept of nationhood has significant implications in several areas: the development of a public theology; a Christian response to nationalism; the question of how urban mission fits within mission to the nations; and the importance of indigenous languages in cross-cultural mission, especially in the multicultural cities of Europe.

STRESS AND INTERNATIONAL ENTREPRENEURHSIP: The dark side of international entrepreneurship

Entrepreneurship attracts people with high job satisfaction and financial independence. Unfortunately, being deceived by this image, people do not pay attention to side effects of entrepreneurship. This ignorance usually turns into devastating results for entrepreneur’s health and venture performance. Therefore, it is required to seek ways to avoid these situations. The interest of the study lies in understanding of stress influence on international entrepreneurs by considering stress as a negative side effect of international entrepreneurship. To cover the concept of entrepreneurial stress completely, the study was divided into three section presented by following research questions: 1. What are the antecedents of entrepreneurial stress? 2. What are the consequences of entrepreneurial stress? 3. What coping strategies are applied to address entrepreneurial stress? Systematic literature review has been chosen as scientific approach to answer above questions due to the reason that it enables to minimise inconsistencies of both concepts of international entrepreneurship and stress. This method has afforded an opportunity to distinguish such stress causes as role conflict, overload, and ambiguity. Additionally, the study has covered the notion of stress moderators. The author argues that entrepreneurial traits, venture environment, and social support can have influence on degree of stress perception. Further, it has been proven that unaddressed stress could lead to reduction of entrepreneur’s psychological and physiological health. It should be taken into consideration that degree of both job satisfaction and performance would depend on the level of perceived stress. The last part of study emphasises the coping strategies. The author argues that it is important for an international entrepreneur to comprehend his or her and others’ emotions in order to overcome negative consequences of stress. In addition, the author suggests that an international entrepreneur needs to practise job sharing to reduce the amount of work to be completed. Moreover, it is believed that job sharing can help to overcome work-family conflict that prevails among entrepreneurs. The author anticipates that results of study can be beneficial for entrepreneurs who aim to achieve great results.

Ingestion of a bacterivorous ciliate by the oyster Crassostrea gigas: Protozoa as a trophic link between picoplankton and benthic suspension-feeders

The linked concepts of 'microbial loop' and 'protozoan trophic link' have been very well documented in filter-feeding microzooplankton such as copepods, but have not been applied to energy transfer to benthic suspension-feeding macrofauna, with the exception of the recent demonstration of heterotrophic flagellate assimilation by mussels. The oyster Crassostrea gigas obtains energy resources by filtering microalgae (similar to 5 to 100 mu m). However, in turbid estuaries, light-limited phytoplanktonic production cannot entirely account for oyster energy requirements. Conversely, picoplankters (<2 mu m), which are main effecters of coastal energy flow and matter cycling, are not efficiently retained by oyster filtration. Ciliate protozoal as both micro-sized cells (similar to 5 to 100 run) and bacteria grazers, may represent a major intermediary in trophic transfer between picoplankton and metazoa. The ciliate Uronema was intensely cultured and labelled, using the cyanobacteria Synechococcus as an auto-fluorescent biomarker. The labelled ciliates were offered as potential prey to oysters. We report here the first experimental evidence of a significant retention and ingestion of ciliates by oysters, supporting the role of protozoa as a realistic trophic link between picoplankters and filter-feeding bivalves and thus enhancing their potential importance in estuarine microbial food webs.

The Effectiveness of Community-Based Nutrition Education on the Nutrition Status of Under-five Children in Developing Countries. A Systematic Review

Aim This systematic review aimed at examining the best available evidence on the effectiveness of community-based nutrition education in improving the nutrition status of under five children in developing countries. Methods A systematic search of the literature was conducted utilising the following data bases: Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, Medline, and Web of Knowledge. 9 studies were identified for the critical appraisal process. The Joanna Briggs Institute (JBI) critical appraisal check-list for experimental studies was utilised and two reviewers conducted the appraisal process independently. 7 studies were included for this review and data was extracted using the JBI data extraction form for experimental studies. The extracted data was heterogeneous as such narrative synthesis was conducted. Results The nutritional status of children in all studies improved and this was evidenced by increases in weight, height, mid upper arm circumference and reduced morbidity. Key messages about education were age at introduction of complementary foods, nutrition value on different types of feeds found locally and frequency of feeding the children. However, there were varied Results regarding the effects of the intervention on the nutrition status of children. This was attributed by differences in implementers’ characteristics, different intervention strategy and intensity, difference in age of the children at enrolment, pre-existing children’s growth and nutritional status and follow-up periods. In addition to home visiting, conducting group meetings of care givers and community leaders, providing education twice a week and use of cooking demonstrations have shown that they produce highly significant findings. Conclusion The evidence from the identified studies suggests that community- based nutrition education improves the nutrition status of under-five children in developing countries.

INVESTIGATING THE POSTWAR DECLINE OF RACE IN SCIENCE

Race as a biological category has a long and troubling history as a central ordering concept in the life and human sciences. The mid-twentieth century has been marked as the point where biological concepts of race began to disappear from science. However, biological definitions of race continue to penetrate scientific understandings and uses of racial concepts. Using the theoretical frameworks of critical race theory and science and technology studies and an in-depth case study of the discipline of immunology, this dissertation explores the appearance of a mid-century decline of concepts of biological race in science. I argue that biological concepts of race did not disappear in the middle of the twentieth century but were reconfigured into genetic language. In this dissertation I offer a periodization of biological concepts of race. Focusing on continuities and the effects of contingent events, I compare how biological concepts of race articulate with racisms in each period. The discipline of immunology serves as a case study that demonstrates how biological concepts of race did not decline in the postwar era, but were translated into the language of genetics and populations. I argue that the appearance of a decline was due to events both internal and external to the science of immunology. By framing the mid-twentieth century disappearance of race in science as the triumph of an antiracist racial project of science, it allows us to more clearly see the more recent resurgence of race in science as a recycling of older themes and tactics from the racist science projects of the past.
