Applying causal analysis, three questions are answered: "is it rationally irrational for people to be indifferent towards climate change?" "Are Americans inherently more likely than others to hold irrational beliefs about global issues such as climate change?" If so, "is this phenomenon rooted in certain values that constitute the American identity?" The author focuses on specific "American values" and uses statistics and recent empirical studies to find correlations and causality between those values and the exhibited behavior of individuals, while discussing its possible causes and implications. The study concludes that the root cause of irresponsibility of the American citizen towards climate change is a lack of social mechanisms rewarding individuals for holding epistemologically accurate beliefs. The author then proposes a set of general measures to be prioritized in order to improve social reward mechanisms in the American society. If implemented, those measures should be able to effectively enforce epistemic rationality in the U.S. political debate, which is desirable...

244	Beyond Janus Geometry: Characterization of Flow Fields around Nonspherical Photocatalytic Microswimmers Heckel, Sandra, Bilsing, Clemens, Wittmann, Martin, Gemming, Thomas, Büttner, Lars, Czarske, Jürgen, Simmchen, Juliane 16 May 2024 (has links) Catalytic microswimmers that move by a phoretic mechanism in response to a self-induced chemical gradient are often obtained by the design of spherical janus microparticles, which suffer from multi-step fabrication and low yields. Approaches that circumvent laborious multi-step fabrication include the exploitation of the possibility of nonuniform catalytic activity along the surface of irregular particle shapes, local excitation or intrinsic asymmetry. Unfortunately, the effects on the generation of motion remain poorly understood. In this work, single crystalline BiVO₄ microswimmers are presented that rely on a strict inherent asymmetry of charge-carrier distribution under illumination. The origin of the asymmetrical flow pattern is elucidated because of the high spatial resolution of measured flow fields around pinned BiVO₄ colloids. As a result the flow from oxidative to reductive particle sides is confirmed. Distribution of oxidation and reduction reactions suggests a dominant self-electrophoretic motion mechanism with a source quadrupole as the origin of the induced flows. It is shown that the symmetry of the flow fields is broken by self-shadowing of the particles and synthetic surface defects that impact the photocatalytic activity of the microswimmers. The results demonstrate the complexity of symmetry breaking in nonspherical microswimmers and emphasize the role of self-shadowing for photocatalytic microswimmers. The findings are leading the way toward understanding of propulsion mechanisms of phoretic colloids of various shapes. info:eu-repo/classification/ddc/500 ddc:500 info:eu-repo/classification/ddc/600 ddc:600 info:eu-repo/classification/ddc/624 ddc:624

248	Physico-Chemical Processes during Reactive Paper Sizing with Alkenyl Succinic Anhydride (ASA) / Physikochemische Prozesse während der Reaktivleimung mit Alkenyl-Bernsteinsäure-Anhydrid (ASA) Porkert, Sebastian 27 February 2017 (has links) (PDF) Sizing (hydrophobization) is one of the most important process steps within the added-value chain of about 1/3rd of the worldwide produced paper & board products. Even though sizing with so-called reactive sizing agents, such as alkenyl succinic anhydride (ASA) was implemented in the paper industry decades ago, there is no total clarity yet about the detailed chemical and physical mechanisms that lead to their performance. Previous research was carried out on the role of different factors influencing the sizing performance, such as bonding between ASA and cellulose, ASA hydrolysis, size revision as well as the most important interactions with stock components, process parameters and additives during the paper making process. However, it was not yet possible to develop a holistic model for the explanation of the sizing performance given in real life application. This thesis describes a novel physico-chemical approach to this problem by including results from previous research and combining these with a wide field of own basic research and a newly developed method that allows tracing back the actual localization of ASA within the sheet structure. The carried out measurements and trial sets for the basic field of research served to evaluate the stock and process parameters that most dominantly influence the sizing performance of ASA. Interactions with additives other than retention aids were not taken into account. The results show that parameters, such as the content of secondary fibers, the degree of refining, the water hardness as well as the suspension conductivity, are of highest significance. The sample sets of the trials with the major impacting parameters were additionally analyzed by a newly developed localization method in order to better understand the main influencing factors. This method is based on optical localization of ASA within the sheet structure by confocal white light microscopy. In order to fulfill the requirements at magnification rates of factor 100 optical zoom, it was necessary to improve the contrast between ASA and cellulose. Therefore, ASA was pretreated with an inert red diazo dye, which does not have any impact on neither the sizing nor the handling properties of ASA. Laboratory hand sheets that were sized with dyed ASA, were analyzed by means of their sizing performance in correlation to measurable ASA agglomerations in the sheet structure. The sizing performance was measured by ultrasonic penetration analysis. The agglomeration behavior of ASA was analyzed automatically by multiple random imaging of a sample area of approx. 8650 µm² with a minimum resolution for particles of 500 nm in size. The gained results were interpreted by full factorial design of experiments (DOE). The trials were carried out with ASA dosages between 0% and 0.8% on laboratory hand sheets, made of 80% bleached eucalyptus short fiber kraft pulp and 20% northern bleached softwood kraft pulp, beaten to SR° 30, produced with a RDA sheet former at a base weight of 100 g/m² oven dry. The results show that there is a defined correlation between the ASA dosage, the sizing performance and the number and area of ASA agglomerates to be found in the sheet structure. It was also possible to show that the agglomeration behavior is highly influenced by external factors like furnish composition and process parameters. This enables a new approach to the explanation of sizing performance, by making it possible to not only examine the performance of the sizing agent, but to closely look at the predominant position where it is located in the sheet structure. These results lead to the explanation that the phenomenon of sizing is by far not a pure chemical process but rather a more physical one. Based on the gained findings it was possible so far to optimize the ASA sizing process in industrial-scale by means of ~ 50% less ASA consumption at a steady degree of sizing and improved physical sheet properties.

249	Dohledová činnost České národní banky / On Supervision of Financial Markets by Czech National Bank Skácelík, David January 2014 (has links) 1 Abstract This work deals with the performance of supervision over the financial market and the entities operating in the financial market. Part of the work is devoted to consumer protection in the financial market and compensation systems. Because of the fact that the Czech Republic became a member of the European Union in 2004, this work includes also legislation of regulation and supervision of this level, as this treatment significantly predetermines Czech adjustment. Following questions were examined as an example of protecting the interests of clients of supervised entities: - whether there are any tools to protect the client's interests at the level of supervised entities, - what kind of role the supervisory authority has or may have in relation between a supervised entity and its client, - how are the client's financial interests protected in the event of failure of the supervised entity and whether this protection is de lege lata sufficient. The theoretical part of the work briefly describes the institute of supervision, its assorting and forms. The authority of supervisor is discussed in the next part together with the regulations under which the supervision is conducted. Owing to the fact that the scope of supervisory activity of the Czech National Bank is quite extensive, and the objective of...
