351	Can Actant-centric System Analyses and Sustainable Value Proposition Methods be an Approach to Aufficiency? Marwede, Max, Scholz, Ronja 30 June 2022 (has links) To create throughout circular product-service systems (PSS), Circular Design needs to combine methods from life-cycle-thinking, planetary stakeholder analysis as well as user-centric business design. To oversee this complexity ‘zooming in’ (micro level) on specific attributes of a PSS has to alternate with ‘zooming out’ (macro level) to understand the systemic effects of envisioned changes – e. g. undesired consequences or the interdependencies between network partners. In two consecutive projects (www.ecodesigncircle.eu) TU Berlin, Fraunhofer IZM and Design Centres in the Baltic Sea Region developed circular design processes and methods that integrate above mentioned requirements (www.circu-lardesign.tools). Those methods evolved into three formats which support companies in developing sustainable products and services by de-sign: EcoDesign Audit assesses the circular maturity and strategic goals of organizations, EcoDesign Sprint helps companies develop a sustainable product or service concept and EcoDesign Learning Factory interactively teaches how to eco-design. The methods were tested in an iterative pro-cess in over 30 interdisciplinary trainings with designers, engineers and business managers. They are already applied with industry clients. In approximately 35 (online) design trainings we trained more than 350 international professionals working at SMEs, industry, design agencies and consultancies. info:eu-repo/classification/ddc/620 ddc:620
352	The Sacrament Of Violence: Myth And War In C.S. Lewis's Ransom Trilogy Engelhardt, Tanya 01 January 2012 (has links) My primary aim for this study is to illuminate the Ransom trilogy's inherent psychological and spiritual themes, as well as demonstrate how these themes clarify Lewis's philosophical and political goals for the text. Specifically, by investigating Lewis's mythic imagery and suffering motifs in light of psychoanalytic and theological literary criticisms, I elucidate the reasoning behind Lewis's unique—and at times, horrific—portrayal of fear, violence, and death. I also investigate how Lewis integrates his theology with the horrors of personal and intrapersonal suffering, as well as how he utilizes imagination and myth to explicate the practical (or political) implications of his theodicy. As a whole, I present a systematic study of the relationship between the Great War, myth, and the three Ransom novels, one which reveals how Lewis manipulates his personal traumatic experiences to fashion a romantic Christian understanding of evil and violence in the modern world C.s. lewis the ransom trilogy the space trilogy out of the silent planet perelandra that hideous strength sacrament violence myth war theology psychology Literature in English, British Isles

356	Heteronormativität Kleiner, Bettina 27 April 2017 (has links) (PDF) Mit dem Begriff Heteronormativität wird die Naturalisierung und Privilegierung von Heterosexualität und Zweigeschlechtlichkeit in Frage gestellt. Kritisiert werden nicht nur die auf Alltagswissen bezogene Annahme, es gäbe zwei gegensätzliche Geschlechter und diese seien sexuell aufeinander bezogen, sondern auch die mit Zweigeschlechtlichkeit und Heterosexualität einhergehenden Privilegierungen und Marginalisierungen. Der Begriff tauchte erstmalig 1991 in Michael Warners Aufsatz "Introduction: Fear of a Queer Planet" auf. Zentrale Bezugspunkte der Analysen von Heteronormativität stellen Foucaults Untersuchungen zum Zusammenhang von Sexualität und Macht sowie Butlers Theorie der Subjektkonstitution im Rahmen der heterosexuellen Matrix oder der heterosexuellen Hegemonie dar.

357	Identifying exoplanets and unmasking false positives with NGTS Günther, Maximilian Norbert January 2018 (has links) In my PhD, I advanced the scientific exploration of the Next Generation Transit Survey (NGTS), a ground-based wide-field survey operating at ESO’s Paranal Observatory in Chile since 2016. My original contribution to knowledge is the development of novel methods to 1) estimate NGTS’ yield of planets and false positives; 2) disentangle planets from false positives; and 3) accurately characterise planets. If an exoplanet passes (transits) in front of its host star, we can measure a periodic decrease in brightness. The study of transiting exoplanets gives insight into their size, formation, bulk composition and atmospheric properties. Transit surveys are limited by their ability to identify false positives, which can mimic planets and out-number them by a hundredfold. First, I designed a novel yield simulator to optimise NGTS’ observing strategy and identification of false positives (published in Günther et al., 2017a). This showed that NGTS’ prime targets, Neptune- and Earth-sized signals, are frequently mimicked by blended eclipsing binaries, allowing me to quantify and prepare strategies for candidate vetting and follow-up. Second, I developed a centroiding algorithm for NGTS, achieving a precision of 0.25 milli-pixel in a CCD image (published in Günther et al., 2017b). With this, one can measure a shift of light during an eclipse, readily identifying unresolved blended objects. Third, I innovated a joint Bayesian fitting framework for photometry, centroids, and radial velocity cross-correlation function profiles. This allows to disentangle which object (target or blend) is causing the signal and to characterise the system. My method has already unmasked numerous false positives. Most importantly, I confirmed that a signal which was almost erroneously rejected, is in fact an exoplanet (published in Günther et al., 2018). The presented achievements minimise the contamination with blended false positives in NGTS candidates by 80%, and show a new approach for unmasking hidden exoplanets. This research enhanced the success of NGTS, and can provide guidance for future missions.
358	Exocomets at large orbital radii and their inward transport in debris discs Marino Estay, Sebastián January 2018 (has links) Planetary systems are not only composed of planets, but also of km-sized rocky and icy bodies that are confined within belts similar to the Asteroid and Kuiper belt in the Solar System. Mutual collisions within these belts grind down solids producing dust and giving rise to debris discs. Primitive asteroids and comets likely played a major role in the emergence of life on Earth through their delivery of volatiles early in the lifetime of our planet. Cometary impacts, therefore, could be a necessary condition for the emergence of life in exoplanets and the study of debris discs essential to determine the ubiquity of such phenomenon. Moreover, exocometary discs provide a unique window into the origins and outer regions of planetary systems as comets do within our Solar System. Initially, in Chapter 1 I present an overview of the study of exoplanetary systems, focusing on debris discs. I discuss the basics of planet formation, its connection with debris discs, and how these evolve and interact with planets. I also describe how we observe these discs and probe their volatile component that is locked inside exocomets, and some evidence supporting the idea of exocomets venturing into the inner regions of planetary systems. Then, in Chapters 2, 3, 4 and 5 I present new ALMA observations of the systems HD 181327, η Corvi, the multiplanet system 61 Vir and HD 107146, which host debris discs. In the first two, I highlight the derivation of the density structure of their discs and the detection of volatiles being released by exocomets; while in the third and fourth I compare the observations with simulations, which I use to set constraints on the underlying planetesimal distribution and mass and orbital distance of unseen planets. Finally, in Chapter 6 I present result obtained from N-body simulations to study the process of inward transport of comets by a multiplanetary system and how these can deliver material to inner planets and explain the frequently observed exozodiacal dust. To conclude, in Chapter 7 I summarise the results and conclusions of this dissertation and discuss ongoing and future work.
359	CCM3 as applied to an idealized all land zonally symmetric planet, Terra Blanda 3 Mahajan, Salil 17 February 2005 (has links) Community Climate Model 3 (CCM3) is run on an idealized all land zonally symmetric planet (Terra Blanda) with no seasonality, no snow and fixed soil moisture to obtain a stationary time series effectively much longer than conventional runs with geography and seasons. The surface temperature field generated is studied to analyze the spatial and temporal spectra, estimate the length scale and time scale of the model, and test the linearity of response to periodic and steady heat source forcings. The length scale of the model is found to be in the range of 1000-2000 km and the time scale is estimated to be 24 days for the global average surface temperature field. The response of the global average temperature is found to be fairly linear to periodic and the steady heat source forcings. The results obtained are compared with the results of a similar study that used CCM0. Fluctuation Dissipation theorem is also tested for applicability on CCM3. The response of the surface temperature field to a step function forcing is demonstrated to be very similar to the decay of naturally occurring anomalies, and the auto-correlation function. Return period of surface temperature anomalies is also studied. It is observed that the length of the data obtained from CCM3, though sufficient for analysis of first and second moments, is significantly deficient for return period analysis. An AR1 process is simulated to model the global averaged surface temperature of Terra Blanda 3 to assess the sampling error associated with short runs.
