No full textThe introductory chapter of “Infrastructural Gazing on Global Finance” delves into the often overlooked yet critical role of financial infrastructures in shaping socio-economic and geopolitical landscapes. Financial infrastructures, while typically operating in the background, have been thrust into public discourse due to events such as the COVID-19 pandemic and international sanctions against Russia. This chapter introduces the concept of “infrastructural gazing,” a heuristic that explores the socio-technical processes underlying financial systems, emphasizing their political and social implications. The approach links micro-level financial transactions to macro-level trends, highlighting how mundane financial infrastructures influence power dynamics, inclusion, and inequality. The chapter addresses the differing sections of the handbook, including the transformative effects of digitalization, the rise of central bank digital currencies, and disruptions posed by tech giants, illustrating how financial infrastructures both stabilize and challenge existing power structures. By moving beyond a narrow technical perspective, the volume emphasizes the socio-political stakes embedded in financial systems, and their relevance for scholars, policymakers, and citizens

Real-Time X-ray Scattering Discovers Rich Phase Behavior in PbS Nanocrystal Superlattices during in Situ Assembly
No full textDuring the self-organization of colloidal semiconductor nanoparticles by solvent evaporation, nanoparticle interactions are substantially determined by the organic ligands covering the inorganic core. However, the influence of the ligand grafting density on the assembly pathway is often not considered in experiments. Here, we carry out an in situ synchrotron small-angle X-ray scattering and X-ray cross-correlation analysis study of the real-time assembly of oleic acid-capped PbS nanocrystals at a low ligand coverage of 2.7 molecules/nm2. With high temporal and spatial resolution, we monitor the transitions from the colloidal suspension through the solvated superlattice states into the final dried superstructure. In a single in situ experiment, we observe a two-dimensional hexagonal, hexagonal close-packed, body-centered cubic, body-centered tetragonal (with different degrees of tetragonal distortion), and face-centered cubic superlattice phases. Our results are compared to the self-organization of PbS nanocrystals with a higher ligand coverage up to 4.5 molecules/nm2, revealing different assembly pathways. This highlights the importance of determining the ligand coverage in assembly experiments to approach a complete understanding of the assembly mechanism as well as to be able to predict and produce the targeted superstructures

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Sectoral job effects of trade: An input-output analysis for Germany
No full textThe current globalisation process is characterized by the emergence of global value chains. That is, production processes are becoming increasingly geographically fragmented. Not only are final goods traded internationally, but in particular, trade in intermediate goods and services has increased significantly over time. In the industrialised countries, the manufacturing sectors were the first that were compelled to face the challenges of globalisation. When services were still considered non-tradable, manufacturing firms had already decided to relocate their production sites to developing or emerging economies, due to lower wage levels abroad and increasing price competition domestically. In this paper, we use input-output analysis to explore the relationship between trade and both job creation and job destruction in the German manufacturing industry in 2005. The results show that being integrated into the world economy is advantageous for the German economy. In 2005, the net exports of the manufacturing industries led to trade-induced job gains of around 2,400,000. This figure is equivalent to 6.2 per cent of total German employment. Furthermore, the job effects of trade were positive for a large majority of countries. The greatest job gains resulted from trade with the United States, the United Kingdom and France. Interestingly, even trade with the new EU Member States is beneficial in terms of job creation. --input-output analysis,international trade,employment
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
