description: Denoising diffusion models have emerged as a powerful tool for various image generation and editing tasks, facilitating the synthesis of visual content in an unconditional or input-conditional manner. The core idea behind them is learning to reverse the process of gradually adding noise to images, allowing them to generate high-quality samples from a complex distribution. In this survey, we provide an exhaustive overview of existing methods using diffusion models for image editing, covering both theoretical and practical aspects in the field. We delve into a thorough analysis and categorization of these works from multiple perspectives, including learning strategies, user-input conditions, and the array of specific editing tasks that can be accomplished. In addition, we pay special attention to image inpainting and outpainting, and explore both earlier traditional context-driven and current multimodal conditional methods, offering a comprehensive analysis of their methodologies. To further evaluate the performance of text-guided image editing algorithms, we propose a systematic benchmark, EditEval, featuring an innovative metric, LMM Score. Finally, we address current limitations and envision some potential directions for future research. The accompanying repository is released at https://github.com/SiatMMLab/Awesome-Diffusion-Model-Based-Image-Editing-Methods.

description: We propose a scheme for generating a high-purity single photon on the basis of cavity quantum electrodynamics (QED). This scheme employs a four-level system including two excited states, two ground states, and two driving lasers; this structure allows the suppression of the re-excitation process due to the atomic decay, which is known to significantly degrade the single-photon purity in state-of-the-art photon sources using a three-level system. Our analysis shows that the re-excitation probability arbitrarily approaches zero without sacrificing the photon generation probability when increasing the power of the driving laser between the excited states. This advantage is achievable by using current cavity-QED technologies. Our scheme can contribute to developing distributed quantum computation or quantum communication with high accuracy.

description: I will argue that the modern can be viewed as a stage of apprenticeship in an ethics of responsibility. The debates on racial slavery in the Americas reveal a fractured modernity, where a counter-discourse of domination coexists with a totalising impulse. The complicity of humanism and oppression marks the consolidation of a racialized, autonomous and rational modern subject defined against its ‘others’. However, I suggest that Derridean critiques of humanism, such as those presented in Robert Young’s White Mythologies, perpetuate the links between humanism and colonialism. The ‘game with Hegel’ is kept in play through a rigid dichotomy between modernity and post modernity. By reducing modern discourse to a synthesis between thesis and antithesis, they do not allow for the possibility of non-coincidence between two contraries. Fanon’s emphasis on lived experience, Arendt’s enlarged mentality, and Levinas’s non-ontological transcendence provide a break with the complicity between humanism and colonialism. While Fanon articulates the perplexities inherent in finding a path from the universal to the particular, Arendt and Levinas give two solutions, one political and the other ethical, to this problematisation. Arendt privileges the safeguarding of a space of plurality through law. Levinas emphasises the ethical relationship between same and Other, where the latter is transcendent and therefore unassailable by the former. This thesis aims to open and reveal gaps, by pointing to ways of thinking humanism that problematise the common reduction of the humanist legacy to a totalising outlook.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Machine learning in atomistic materials science has grown to become a powerful tool, with most approaches focusing on atomic arrangements, typically decomposed into local atomic environments. This approach, while well-suited for machine-learned interatomic potentials, is conceptually at odds with learning complex intrinsic properties of materials, often driven by spectral properties commonly represented in reciprocal space (e.g., band gaps or mobilities) which cannot be readily atomically partitioned. For such applications, methods which represent the electronic rather than the atomic structure could be more promising. In this work, we present a general framework focused on electronic-structure descriptors which take advantage of the natural symmetries and inherent interpretability of physical models. Using this framework, we formulate two such representations and apply them respectively to measuring the similarity of carbon nanotubes and barium titanate polymorphs, and to the discovery of novel transparent conducting materials (TCMs) in the Materials Cloud 3D database (MC3D). A random forest classifier trained on 1% of the materials in the MC3D is able to correctly label 76% of entries in database which meet common screening criteria for promising TCMs.

Damit wurde erstmals in der Geschichte der VR China ein gesetzgebendes Organ durch eine Mehrparteien-Konkurrenzwahl berufen. Die Wahl wurde nicht nur ohne erkennbare Eingriffe von Seiten Beijings abgehalten, sondern führte auch zu einem Wiedereinzug Beijing-kritischer Politiker, die nach dem Souveränitätswechsel im letzten Jahr vorübergehend ihren Sitz in der Legislative verloren hatten. Vor dem Hintergrund der Einparteiherrschaft in der VR China stellen die Hongkonger Wahlen und die Zulassung einer politischen Opposition trotz vielfältiger Verzerrungen in Wahlverfahren und Wahlergebnissen ein historisches Ereignis dar.

description: Advertising changes the consumer. Through advertising exposures, a consumer becomes aware of the advertised product, becomes interested in it, develops a desire, and makes a purchase decision (the hierarchy of effects model). However, despite a wide use of email advertising by advertisers, how email advertising persuades and how it changes the consumer have not been studied. This dissertation focuses on the measurement of email advertising effectiveness based on the hierarchy of effects (awareness – interest – desire – action, AIDA) model which highlights each email advertising recipient’s journey towards a purchasing decision. This dissertation investigates the following research questions: which factors influence the open rate of email advertising (study 1); which factors influence the click rate of email advertising (study 2); and which factors influence the overall purchase behavior (study 3; or company sales). First, study 1 analyzes the factors that influence the open rate of email advertising and identifies five factors including subject line with price discount promotion, subject line stated in a loss frame, utilitarian product attribute, subject line describing a company’s social responsibility and socially responsible actions, and subject line describing holiday celebration that have positive impacts on the email recipient’s opening rate. Also, study 1 finds out that the short interval between email sendings decreases the open rate. Study 2 investigates the effects of email advertising body contents and finds that body contents with price discount promotion, body contents stated in a loss frame, and body contents describing seasonal appeal increase the recipient’s click rate when they open the email advertising. Finally, study 3 examines which factors influence the overall purchase behavior and finds that one factor, body contents with price discount promotion, increases most the purchase rate. This dissertation contributes to the understanding of the effects of email advertising on consumer behaviors. Notably, the three studies in this dissertation examining the factors that influence on the email advertising recipient’s opening, clicking, and purchasing actions contribute to empirical testing of the hierarchy model of advertising effects. The findings of this dissertation can also help advertisers and marketers strategically plan their advertising to achieve their goal

description: In the field of chemical structure recognition, the task of converting molecular images into machine-readable data formats such as SMILES string stands as a significant challenge, primarily due to the varied drawing styles and conventions prevalent in chemical literature. To bridge this gap, we proposed MolNexTR, a novel image-to-graph deep learning model that collaborates to fuse the strengths of ConvNext, a powerful Convolutional Neural Network variant, and Vision-TRansformer. This integration facilitates a more detailed extraction of both local and global features from molecular images. MolNexTR can predict atoms and bonds simultaneously and understand their layout rules. It also excels at flexibly integrating symbolic chemistry principles to discern chirality and decipher abbreviated structures. We further incorporate a series of advanced algorithms, including an improved data augmentation module, an image contamination module, and a post-processing module for getting the final SMILES output. These modules cooperate to enhance the model's robustness to diverse styles of molecular images found in real literature. In our test sets, MolNexTR has demonstrated superior performance, achieving an accuracy rate of 81-97%, marking a significant advancement in the domain of molecular structure recognition.

description: The pursuit of quantum-enhanced parameter estimations without the need for nonclassical initial states has long been driven by the goal of achieving experimentally accessible quantum metrology. In this work, employing a coherent averaging mechanism, we prove that the prototypical cavity quantum electrodynamics (QED) system, such as the Tavis-Cummings model, enables us to achieve not only the Heisenberg scaling (HS) precision in terms of the average photon number but also the double-HS sensitivity concerning both the average photon and atom numbers. Such a double sensibility can be experimentally realized by introducing either photon- or atom-number fluctuations through quantum squeezing. Furthermore, we discuss the methodology to achieve this double-HS precision in a realistic experimental circumstance where the squeezing is not perfect. Our results provide insights into understanding the coherent averaging mechanism for evaluating quantum-enhanced precision measurements and also present a usable metrological application of the cavity QED systems and superconducting circuits.

description: In emergencies, high stake decisions often have to be made under time pressure and strain. In order to support such decisions, information from various sources needs to be collected and processed rapidly. The information available tends to be temporally and spatially variable, uncertain, and sometimes conflicting, leading to potential biases in decisions. Currently, there is a lack of systematic approaches for information processing and situation assessment which meet the particular demands of emergency situations. To address this gap, we present a Bayesian network-based method called ERIMap that is tailored to the complex information-scape during emergencies. The method enables the systematic and rapid processing of heterogeneous and potentially uncertain observations and draws inferences about key variables of an emergency. It thereby reduces complexity and cognitive load for decision makers. The output of the ERIMap method is a dynamically evolving and spatially resolved map of beliefs about key variables of an emergency that is updated each time a new observation becomes available. The method is illustrated in a case study in which an emergency response is triggered by an accident causing a gas leakage on a chemical plant site.

Older Adults’ Safety and Security Online: A Post-Pandemic Exploration of Attitudes and Behaviors
Creators: name: Pacheco, Edgar
Publisher: name: Journal of Digital Media & Interaction
Year: 2024

description: Older adults’ growing use of the internet and related technologies, further accelerated by the COVID-19 pandemic, has prompted not only a critical examination of their behaviors and attitudes about online threats but also a greater understanding of the roles of specific characteristics within this population group. Based on survey data and using descriptive and inferential statistics, this empirical study delves into this matter. The behaviors and attitudes of a group of older adults aged 60 years and older (n=275) regarding different dimensions of online safety and cybersecurity are investigated. The results show that older adults report a discernible degree of concern about the security of their personal information. Despite the varied precautions taken, most of them do not know where to report online threats. What is more, regarding key demographics, the study found some significant differences in terms of gender and age group, but not disability status. This implies that older adults do not seem to constitute a homogeneous group when it comes to attitudes and behaviors regarding safety and security online. The study concludes that support systems should include older adults in the development of protective measures and acknowledge their diversity. The implications of the results are discussed and some directions for future research are proposed.

description: Model-free reinforcement learning is a promising approach for autonomously solving challenging robotics control problems, but faces exploration difficulty without information of the robot's kinematics and dynamics morphology. The under-exploration of multiple modalities with symmetric states leads to behaviors that are often unnatural and sub-optimal. This issue becomes particularly pronounced in the context of robotic systems with morphological symmetries, such as legged robots for which the resulting asymmetric and aperiodic behaviors compromise performance, robustness, and transferability to real hardware. To mitigate this challenge, we can leverage symmetry to guide and improve the exploration in policy learning via equivariance/invariance constraints. In this paper, we investigate the efficacy of two approaches to incorporate symmetry: modifying the network architectures to be strictly equivariant/invariant, and leveraging data augmentation to approximate equivariant/invariant actor-critics. We implement the methods on challenging loco-manipulation and bipedal locomotion tasks and compare with an unconstrained baseline. We find that the strictly equivariant policy consistently outperforms other methods in sample efficiency and task performance in simulation. In addition, symmetry-incorporated approaches exhibit better gait quality, higher robustness and can be deployed zero-shot in real-world experiments.

description: The quantum-corrected black hole model demonstrates significant potential in the study of gravitational lensing effects. By incorporating quantum effects, this model addresses the singularity problem in classical black holes. In this paper, we investigate the impact of the quantum correction parameter on the lensing effect based on the quantum corrected black hole model. Using the black holes $M87^*$ and $Sgr A^*$ as our subjects, we explore the influence of the quantum correction parameter on angular position, Einstein ring, and time delay. Additionally, we use data from the Event Horizon Telescope observations of black hole shadows to constrain the quantum correction parameter. Our results indicate that the quantum correction parameter significantly affects the lensing coefficients $\bar{a}$ and $\bar{b}$, as well as the Einstein ring. The position $θ_{\infty}$ and brightness ratio $S$ of the relativistic image exhibit significant changes,with deviations on the order of magnitude of $\sim 1μas$ and $\sim 0.01μas$, respectively. The impact of the quantum correction parameter on the time delay $ΔT_{21}$ is particularly significant in the $M87^*$ black hole, with deviations reaching up to several tens of hours. Using observational data from the Event Horizon Telescope(EHT) of black hole shadows to constrain the quantum correction parameter, the constraint range under the $M87^*$ black hole is $0\le \fracα{M^2}\le 1.4087$ and the constraint range under the $Sgr A^*$ black hole is $0.9713\le \fracα{M^2}\le 1.6715$ . Although the current resolution of the EHT limits the observation of subtle differences, future high-resolution telescopes are expected to further distinguish between the quantum-corrected black hole and the Schwarzschild black hole, providing new avenues for exploring quantum gravitational effects.

description: In this work we introduce the notion of an angular spectrum for a linear discrete time nonautonomous dynamical system. The angular spectrum comprises all accumulation points of longtime averages formed by maximal principal angles between successive subspaces generated by the dynamical system. The angular spectrum is bounded by angular values which have previously been investigated by the authors. In this contribution we derive explicit formulas for the angular spectrum of some autonomous and specific nonautonomous systems. Based on a reduction principle we set up a numerical method for the general case; we investigate its convergence and apply the method to systems with a homoclinic orbit and a strange attractor. Our main theoretical result is a theorem on the invariance of the angular spectrum under summable perturbations of the given matrices (roughness theorem). It applies to systems with a so-called complete exponential dichotomy (CED), a concept which we introduce in this paper and which imposes more stringent conditions than those underlying the exponential dichotomy spectrum.

description: Recently entanglement suppression was proposed to be one possible origin of emergent symmetries. Here we test this conjecture in the context of heavy meson scatterings. The low-energy interactions of $D^{(*)}\bar D^{(*)}$ and $D^{(*)} D^{(*)}$ are closely related to the hadronic molecular candidates $X(3872)$ and $T_{cc}(3875)^+$, respectively, and can be described by a nonrelativistic effective Lagrangian manifesting heavy-quark spin symmetry, which includes only constant contact potentials at leading order. We explore entanglement suppression in a tensor-product framework to treat both the isospin and spin degrees of freedom. Using the $X(3872)$ and $T_{cc}(3875)^+$ as inputs, we find that entanglement suppression indeed leads to an emergent symmetry, namely, a light-quark spin symmetry, and as such the $D^{(*)}\bar D^{(*)}$ or $D^{(*)} D^{(*)}$ interaction strengths for a given total isospin do not depend on the total angular momentum of light (anti)quarks. The $X(3872)$ and $T_{cc}(3875)^+$ are predicted to have five and one isoscalar partner, respectively, while the corresponding partner numbers derived solely from heavy-quark spin symmetry are three and one, respectively. The predictions need to be confronted with experimental data and lattice quantum chromodynamics results to further test the entanglement suppression conjecture.

description: Using the nonlinear shallow water equations as benchmark, we demonstrate that a simulation with the ICON-O ocean model with a 20km resolution that is frequently corrected by a U-net-type neural network can achieve discretization errors of a simulation with 10km resolution. The network, originally developed for image-based super-resolution in post-processing, is trained to compute the difference between solutions on both meshes and is used to correct the coarse mesh every 12h. Our setup is the Galewsky test case, modeling transition of a barotropic instability into turbulent flow. We show that the ML-corrected coarse resolution run correctly maintains a balance flow and captures the transition to turbulence in line with the higher resolution simulation. After 8 day of simulation, the $L_2$-error of the corrected run is similar to a simulation run on the finer mesh. While mass is conserved in the corrected runs, we observe some spurious generation of kinetic energy.

description: We prove that Villain interaction applied to lattice gauge theory can be obtained as the limit of both Wilson and Manton interactions on a larger graph which we call the {\em carpet graph.} This is the lattice gauge theory analog of a well-known property for spin $O(N)$ models where Villain type interactions are the limit of $\mathbb{S}^{N-1}$ spin systems defined on a {\em cable graph}.
 Perhaps surprisingly in the setting of lattice gauge theory, our proof also applies to non-Abelian lattice theory such as $SU(3)$-lattice gauge theory and its limiting Villain interaction.
 In the particular case of an Abelian lattice gauge theory, this allows us to extend the validity of Ginibre inequality to the case of the Villain interaction.

description: Die Insel Taiwan wurde 1895 als Folge der Niederlage Chinas im chinesisch-japanischen Krieg an Japan abgetreten und 1945 - nach der Kapitulation Japans im Zweiten Weltkrieg - wieder von China zurückgenommen. Während der japanischen Besatzung herrschte eine koloniale Wirtschaftspolitik. Auch nach dem Ende der Kolonialzeit führte die chinesische Regierung infolge des Bürgerkrieges eine staatlich reglementierte Wirtschaftspolitik fort. 1949 verlor die KMT (Kuomintang)-Regierung das chinesische Festland an die Kommunisten und hat seitdem nur noch Taiwan sowie einige Frontinseln vor der südöstlichen chinesischen Küste unter ihrer Kontrolle. Wegen Devisenmangels wurden die Importe streng eingeschränkt und zunächst die Konsumgüterindustrie ausgebaut, vor allem Textilien und Nahrungsmittelverarbeitung. Im Laufe der 60er und 70er Jahre entwickelte sich die Leichtindustrie so weit, daß die Produkte neben dem Eigenbedarf auch exportiert wurden. Darüber hinaus nahm die Insel viele infolge der Wirtschaftsumstrukturierung von den Industrieländern ausgelagerte arbeitsintensive sowie umweltbelastende Produktionen auf, die in erster Linie auch der Exportwirtschaft dienten.

Yuan - Anlaß genug, um den derzeitigen Zustand der chinesischen Streitkräfte etwas genauer auszuleuchten. Dabei soll es weniger um die Organisation, den Rüstungsstand oder den geschichtlichen Hintergrund der VBA,1 als vielmehr um Aspekte gehen, in denen sich die VBA von anderen Armeen unterscheidet und die überdies auch Zweifel aufkommen lassen, ob es sich bei der VBA überhaupt noch um eine Armee herkömmlichen Zuschnitts handelt.

description: Die Finanz- und Wirtschaftskrise in einer Reihe asiatischer Nachbarstaaten überschattete die wirtschaftliche Entwicklung der VR China von Mitte 1997 an und wirkt auch 1998 nach. Aufgrund seiner Position als regionales Finanzzentrum in Asien war die SVR Hongkong allerdings von der Krise bisher weitaus stärker betroffen als Festlandchina. Beschränkungen im Kapitalverkehr mit dem Ausland schützten China vor spekulativen Attacken gegen die Bindung des Renminbi an den US-Dollar als Leitwährung. So unterliegt der festlandchinesische Devisen- und Kapitalmarkt nach wie vor strengen Auflagen, und die festlandchinesische Währung ist nicht frei konvertibel. Hongkong dagegen mußte sich gegen Angriffe auf den Wechselkurs, der nach wie vor in fester Relation zum US- Dollar steht, mit Rückgriff auf seine hohen Devisenreserven und Heraufsetzung der Zinsen zur Wehr setzen. Dies geschah in Absprache mit der Zentralregierung in Beijing, die ankündigte, zur Stabilisierung des Hongkong-Dollars notfalls die eigenen Devisenreserven einzusetzen.

description: Tenant-landlord relationships exhibit a power asymmetry where landlords' power to evict the tenants at a low-cost results in their dominating status in such relationships. Tenant concerns are thus often unspoken, unresolved, or ignored and this could lead to blatant conflicts as suppressed tenant concerns accumulate. Modern machine learning methods and Large Language Models (LLM) have demonstrated immense abilities to perform language tasks. In this study, we incorporate Latent Dirichlet Allocation (LDA) with GPT-4 to classify Reddit post data scraped from the subreddit r/Tenant, aiming to unveil trends in tenant concerns while exploring the adoption of LLMs and machine learning methods in social science research. We find that tenant concerns in topics like fee dispute and utility issues are consistently dominant in all four states analyzed while each state has other common tenant concerns special to itself. Moreover, we discover temporal trends in tenant concerns that provide important implications regarding the impact of the pandemic and the Eviction Moratorium.

description: The goal of this contribution is to provide worksheets in Coq for students to learn about divisibility and binomials. These basic topics are a good case study as they are widely taught in the early academic years (or before in France). We present here our technical and pedagogical choices, the numerous exercises we developed and a small experiment we conducted on two students. As expected, it required additional {\Coq} material such as other lemmas and dedicated tactics. The worksheets are freely available and flexible in several ways.

description: Hongkongs größte Wirtschaftsorganisationen riefen Ende April die Banken dazu auf, ihre Zinsen zu senken. Dies soll die wirtschaftliche Belastung der Unternehmen erleichtern, die von dem Konjunkturabschwung betroffen sind. Henry Tang, Vorsitzender des Hongkonger Unternehmerverbandes, warnte im Zusammenhang mit dem Konjunkturabschwung vor einem weiteren Anstieg der Arbeitslosenquote und forderte eine Zinssenkung. Auch James Tien, Vorsitzender der Hongkonger Handelskammer, setzte sich für eine Entlastung der Unternehmen über niedrigere Zinsen ein.

description: This study investigates the generalization capabilities and robustness of purely deep learning (DL) models and hybrid models based on physical principles in fluid dynamics applications, specifically focusing on iteratively forecasting the temporal evolution of flow dynamics. Three autoregressive models were compared: a hybrid model (POD-DL) that combines proper orthogonal decomposition (POD) with a long-short term memory (LSTM) layer, a convolutional autoencoder combined with a convolutional LSTM (ConvLSTM) layer and a variational autoencoder (VAE) combined with a ConvLSTM layer. These models were tested on two high-dimensional, nonlinear datasets representing the velocity field of flow past a circular cylinder in both laminar and turbulent regimes. The study used latent dimension methods, enabling a bijective reduction of high-dimensional dynamics into a lower-order space to facilitate future predictions. While the VAE and ConvLSTM models accurately predicted laminar flow, the hybrid POD-DL model outperformed the others across both laminar and turbulent flow regimes. This success is attributed to the model's ability to incorporate modal decomposition, reducing the dimensionality of the data, by a non-parametric method, and simplifying the forecasting component. By leveraging POD, the model not only gained insight into the underlying physics, improving prediction accuracy with less training data, but also reduce the number of trainable parameters as POD is non-parametric. The findings emphasize the potential of hybrid models, particularly those integrating modal decomposition and deep learning, in predicting complex flow dynamics.

description: We compute the minimal exponent of the affine cone over a complete intersection of smooth projective hypersurfaces intersecting transversely. The upper bound for the minimal exponent is proved, more generally, in the weighted homogeneous setting, while the lower bound is deduced from a general lower bound in terms of a strong factorizing resolution in the sense of Bravo and Villamayor.

description: We address the problem of characterizing the aggregate flexibility in populations of electric vehicles (EVs) with uncertain charging requirements. Extending upon prior results that provide exact characterizations of aggregate flexibility in populations of electric vehicle (EVs), we adapt the framework to encompass more general charging requirements. In doing so we give a characterization of the exact aggregate flexibility as a generalized polymatroid. Furthermore, this paper advances these aggregation methodologies to address the case in which charging requirements are uncertain. In this extended framework, requirements are instead sampled from a specified distribution. In particular, we construct robust aggregate flexibility sets, sets of aggregate charging profiles over which we can provide probabilistic guarantees that actual realized populations will be able to track. By leveraging measure concentration results that establish powerful finite sample guarantees, we are able to give tight bounds on these robust flexibility sets, even in low sample regimes that are well suited for aggregating small populations of EVs. We detail explicit methods of calculating these sets. Finally, we provide numerical results that validate our results and case studies that demonstrate the applicability of the theory developed herein.

Asien im Jahre 2050: Versuch einer virtuellen Umrißbestimmung
Creators: name: Weggel, Oskar
Publisher: name: China aktuell
Year: 2019

description: Kapitel 1 hat ein virtuelles Panoramabild Asiens im 21. Jh. gezeichnet. In Kapitel 2 sind die potentiellen Träger künftiger Entscheidungen und in Kapitel 3 die künftigen Hauptthemen skizziert worden. Kapitel 4 hat die wirtschafts-, die politik- und die sozialstrategischen Strategien präsentiert und Kapitel 5 Stilfragen behandelt, also die Machart, in der Politik voraussichtlich immer stärker in Erscheinung tritt. Kapitel 6 ging auf die inneren Bestimmungsgründe (Nativismus, „Asiatismus“, Nationalismus) ein, deren spezifische Ausrichtung erst verständlich werden läßt, warum sich die verschiedenen politischen Systeme in dieser oder jener Situation so - und nicht anders - verhalten. In Kapitel 7 ging es um die Frage, ob die asiatischen Kulturen und Lebensformen sich in ihrer Authentizität erhalten können oder ob sie am Ende nicht doch das Schicksal der Verwestlichung erleiden. Im vorliegenden Kapitel 8 stellt sich die abschließende Frage, ob „Asien“ für Europa zum Konkurrenten, ja zur „Gefahr“ werden könnte oder ob am Ende nicht eher Kooperation und Partnerschaft zu erwarten sind.
