I am most concerned with those settler-colonialisms that persist at the centers of world capitalism, and examine bow this social context often produces an ideology that relegates the concrete reality of settler-colonialism to the past, pushing its existence under supposedly “modem” social relations. Since Frantz Fanon＇s analysis of settler-colonialism, and the class contradiction between colonizer and colonized, was developed in an era where settler-colonialism was partially defined by the relationship between motherland and colony, some often imagine that the era of settler-colonialism is over. Clearly settler-colonialism did not vanish along with this distinction; internal colonies are retained in North America, for example, and the state of Israel is perhaps the most recent historical of this type of colonialism since it was settled and established in the 20th century. Moreover, there is often talk of a “world-wide indigenous movement” which claims to represent a global anti-colonialist front. The point of my paper, therefore, is to examine how settler-colonialism functions and persists when the settler-colony has become synonymous with the motherland. In this social context, colonizers often imagine themselves as the native inhabitants, while those who remain colonized are pushed even further out of history than they were during the previous era of settler-colonialism.展开更多

Said. With the understanding and the definition of post-colonialism, the paper is to analyze phenomena of the movie 2012 and Avatar from several aspects. Firstly, the ＂other＂ is the first angle to be talked about. In the Westerners＇ perspective, they are the center of the world, and they dominate the world. Their rules are the accepted rules, and people of different origin or different cultures are all called ＂other＂. Secondly, it is the degeneration of eastern culture. In the complex of the degeneration of the culture, the demonization of the under-developed nations, the dominant language of English in the communication with the people around, feminization of the characters in the movies, and the updated colonialism of the colonized countries are to be mentioned.展开更多

Hormone thyroxin is involved in the metabolism of several nutrients, the regulation of enzymes and differentiation of cells, tissues and organs. Iodine deficiency (ID) impairs the development of the brain and nervous system. It affects cognitive capacity, educability, productivity and child mortality. ID hinders physical strength and causes reproductive failure. The objective of this paper is to explore if the health impacts of ID are more common and severe among women. Design: Using primary data (notes from a visit) and secondary data, this paper examines if the effects of ID are more common and severe among Oromo women inEthiopia. Findings: The health impacts of ID are more common and severe among women. Conclusions: ID is an easily preventable nutritional problem. In Oromia, the persistence of ID is explained by the Ethiopian government’s colonial social policies. Preventing ID should be seen as part of the efforts we make to enhance capacity building, promote health, gender equity and social justice. Implications: Iodine deficiency has a wide range of biological, social, economic and cultural impacts. Preventing ID can be instrumental in bringing about gender equity and building the capacity of people.展开更多

The colonialism, one of her most concerned topics, is often revealed in many of her early works and so is in The Old Chief Mshlanga. In this story, Lessing first employs a third-person narrator and then a first-person narrator, both of whom adopt the narrative perspective from the protagonist within the story.What the two different person-narrators really differ is in the narrative voice. The narrative voice of the third-person narrator comes from the narrator outside the story, while the other one comes from the protagonist within the story. It is by means of the same perspective and the different narrative voice that Lessing vividly reveals the colonialism in The Old Chief Mshlanga.展开更多

With Harbin and its urban planning from 1898 to 1917 as the subject of study from the perspective of planning historiography, this paper probes into the driving force behind Harbin's early modern urban development, historical phasing and characteristics of its urban planning, as well as evolution of planning and construction activities during this period. The findings reveal that Harbin's urban planning and construction activities were closely linked to Russia's political and economic interests and also reflected the political game between the powers led by Japan and Russia in the Manchurian region.展开更多

The spread of overseas Chinese economic and social networks followed a Skinnerian model in which large urban congrggations wielded more political and economic authority than did smaller, rural congr@ations. By examining the impacts of French colonialism upon overseas Chinese networks within Indochina and upon overseas connections with their Chinese native places, this paper proposes that the Skinnerian model of local-system hierarchy fits quite comfortably when applied to the world of French colonial Indochina and its overseas Chinese. Furthermore, it argues that French colonialism actually reinforced the Skinnerian hierarchy of politics and markets in ways that endured long after the collapse of Imperial China.展开更多

文摘The microstructure of high Nb-TiAl alloys was optimized by the addition of a small amount of Ta elements to further improve their properties.A series of Ti46Al1.5Cr8Nb-xTa(x=0.2,0.4,0.6,0.8,1.0,at.%)alloys were prepared by vacuum arc melting.The microstructure,mechanical properties,and related influencing mechanisms were systematically investigated.The results indicate that the solidification microstructure of the Ti46Al1.5Cr8Nb-xTa alloys comprises theγ-TiAl phase,α_(2)-Ti_(3)Al phase,and B2 phase.As the Ta content increases from 0.2 at.%to 1.0 at.%,the content ofα_(2)phase and B2 phase increases,while theγphase content decreases.Among them,the B2 phase shows the most pronounced change,being significantly refined,with its content increasing from 12.49%to 21.91%.In addition,the average size of the lamellar colony decreases from 160.65 to 94.44μm.The addition of the Ta element shifts the solidification path toward lower aluminum concentrations,leading to changes in phase content.The tantalum-induced increase in the B2 phase and enhanced supercooling at the solidification front provide the basis for lamellar colony refinement.Compressive testing at room temperature reveals that the Ti46 Al1.5 Cr8 Nb0.4 Ta alloy exhibits optimal compressive properties,achieving a compressive strength of 2,434 MPa and a compressive strain of 33.1%.The improvement of its properties is attributed to a combination of lamellar colony refinement,solid solution strengthening resulting from the incorporation of Ta element,and a reduction in the c/a of theγphase.

文摘With the increasing complexity of logistics operations,traditional static vehicle routing models are no longer sufficient.In practice,customer demands often arise dynamically,and multi-depot systems are commonly used to improve efficiency.This paper first introduces a vehicle routing problem with the goal of minimizing operating costs in a multi-depot environment with dynamic demand.New customers appear in the delivery process at any time and are periodically optimized according to time slices.Then,we propose a scheduling system TS-DPU based on an improved ant colony algorithm TS-ACO to solve this problem.The classical ant colony algorithm uses spatial distance to select nodes,while TS-ACO considers the impact of both temporal and spatial distance on node selection.Meanwhile,we adopt Cordeau’s Multi-Depot Vehicle Routing Problem with Time Windows(MDVRPTW)dataset to evaluate the performance of our system.According to the experimental results,TS-ACO,which considers spatial and temporal distance,is more effective than the classical ACO,which only considers spatial distance.

文摘The Intrusion Detection System(IDS)is a security mechanism developed to observe network traffic and recognize suspicious or malicious activities.Clustering algorithms are often incorporated into IDS;however,conventional clustering-based methods face notable drawbacks,including poor scalability in handling high-dimensional datasets and a strong dependence of outcomes on initial conditions.To overcome the performance limitations of existing methods,this study proposes a novel quantum-inspired clustering algorithm that relies on a similarity coefficient-based quantum genetic algorithm(SC-QGA)and an improved quantum artificial bee colony algorithm hybrid K-means(IQABC-K).First,the SC-QGA algorithmis constructed based on quantum computing and integrates similarity coefficient theory to strengthen genetic diversity and feature extraction capabilities.For the subsequent clustering phase,the process based on the IQABC-K algorithm is enhanced with the core improvement of adaptive rotation gate and movement exploitation strategies to balance the exploration capabilities of global search and the exploitation capabilities of local search.Simultaneously,the acceleration of convergence toward the global optimum and a reduction in computational complexity are facilitated by means of the global optimum bootstrap strategy and a linear population reduction strategy.Through experimental evaluation with multiple algorithms and diverse performance metrics,the proposed algorithm confirms reliable accuracy on three datasets:KDD CUP99,NSL_KDD,and UNSW_NB15,achieving accuracy of 98.57%,98.81%,and 98.32%,respectively.These results affirm its potential as an effective solution for practical clustering applications.

文摘In the wireless energy transmission service composition optimization problem,a key challenge is accurately capturing users’preferences for service criteria under complex influencing factors,and optimally selecting a composition solution under their budget constraints.Existing studies typically evaluate satisfaction solely based on energy transmission capacity,while overlooking critical factors such as price and trustworthiness of the provider,leading to a mismatch between optimization outcomes and user needs.To address this gap,we construct a user satisfaction evaluation model for multi-user and multi-provider scenarios,systematically incorporating service price,transmission capacity,and trustworthiness into the satisfaction assessment framework.Furthermore,we propose a Budget-Aware Preference Adjustment Model that predicts users’baseline preference weights from historical data and dynamically adjusts them according to budget levels,thereby reflecting user preferences more realistically under varying budget constraints.In addition,to tackle the composition optimization problem,we develop a ReflectiveEvolutionary Large Language Model—Guided Ant Colony Optimization algorithm,which leverages the reflective evolution capability of large language models to iteratively generate and refine heuristic information that guides the search process.Experimental results demonstrate that the proposed framework effectively integrates personalized preferences with budget sensitivity,accurately predicts users’preferences,and significantly enhances their satisfaction under complex constraints.
文摘After Cornelius de Pauw,one of the most eminent representatives of the European Enlightenment,had published the second volume of his Recherches philosophiques sur les Américains,which in many ways was even more provocative than the first,a violent debate arose in Berlin,spreading quickly to a number of European countries and especially overseas.There is good reason to identify the first phase of this dispute as the Berlin Debate about the New World,especially when considering that Brandenburg and Prussia had been active colonists and had attempted to secure their share in the European move towards expansion.Was it a coincidence that,in 1769,of all places,this debate entered the heated phase of international dispute about the New World in the Prussian capital,which—after all—was a tranquil and idyllic spot compared to Paris,Amsterdam,or London?Certainly,as King of Prussia,Frederick II was the type of leader who made it clear that he was planning to write new music for the symphony of great political powers.From the beginning,the Prussian King was aware of the far-ranging political dimensions of his most-famous operatic project Montezuma.As he told Francesco Algarotti as early as October 1753,he was aiming to send a precise and memorable political message.Is it possible to understand the libretto from Frederick’s royal hands,the performance of“his”opera with Carl Heinrich Graun’s music,Giuseppe Galli Bibiena’s stage architecture,Giovanna Astrua’s arias,and hundreds of other people involved as a prelude to the Berlin Debate about the New World,which had led to heated discussion in the worldwide République des Lettres since the late 1760s?
文摘Overturning assumptions that nonwestern architecture has been static over time, new scholar- ship focused on colonial and postcolonial architecture and urbanism and on nonwestern modernism has made a significant contnbution to our understanding of the history of architecture. Much more, however, remains to be done. Comparative studies of colonialism, especially between empires, attention to innovation outside Europe and the English-speaking world and more consideration of memory and migration are among the most exciting possible new directions.
文摘In Indochina, overseas Chinese were organized by dialect group into associations called congregations, which shared many of the functions of huiguan in China. The spread of overseas Chinese economic and social networks followed a Skinnerian model in which large urban congrggations wielded more political and economic authority than did smaller, rural congr@ations. By examining the impacts of French colonialism upon overseas Chinese networks within Indochina and upon overseas connections with their Chinese native places, this paper proposes that the Skinnerian model of local-system hierarchy fits quite comfortably when applied to the world of French colonial Indochina and its overseas Chinese. Furthermore, it argues that French colonialism actually reinforced the Skinnerian hierarchy of politics and markets in ways that endured long after the collapse of Imperial China.
