This study uses the 2018 Wellcome Global Monitor on public perceptions of vaccines in 40 African countries to examine the predictors of vaccine hesitancy.It examines levels of hesitancy from a language perspective, comparing French speakers with others, mostly English speakers. Results show that French speakers were significantly more hesitant about importance and safety, while English speakers and others were more hesitant about effectiveness. This reflects the continuing influence of colonial ties on African countries. Respondents with high levels of trust in social actors(such as national government, journalists, people neighborhood, doctors and nurses) were also more hesitant about the safety and effectiveness of vaccines, indicating the importance of non-scientists in influencing vaccine hesitancy. Those with high levels of education were more likely to be hesitant about vaccines in general, indicating that having more education may have an opposite effect. Perception of science as progress was significant for all three hesitancy types, indicating that Africans with more progressive attitudes were less likely to worry about the importance, safety and effectiveness of vaccines. At the country level, there was no overarching predictor, indicating the strong role of local social and cultural factors.These findings improve our understanding of the drivers of vaccine hesitancy in Africa and provide valuable input for future vaccine policy and health-awareness campaigns.展开更多

This study explores the application of critical discourse analysis in post-colonial literary research, focusing on how this method reveals implicit power relations, identity construction, and cultural conflicts within texts. Through in-depth analysis of representative works, this study demonstrates how critical discourse analysis provides new perspectives and methodological tools for post-colonial literary studies. The research finds that critical discourse analysis can effectively deconstruct colonial discourse in texts, reveal authors’ ideological positions, and offer profound insights into understanding the complexity of post-colonial societies. This study not only enriches the methodology of post-colonial literary research, but also provides valuable references for interdisciplinary studies.展开更多

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

Following the analysis of Beauvoir as featured in The Ethics of Ambiguity and The Second Sex, the author first begins by examining the situation and rights of French women colonizer as it relates to the situation of the colonized. And then, the author examines the situation and rights of these women from their own stands as women and in relationships to the situation and rights of white French men. The paper concludes that while French women may have experienced white privilege, they suffered from gender oppression deriving from their second-class status as French colonial subjects.展开更多

All too often, the German invaders are portrayed as omnipotent and intellectually superior to their African allies and opponents. This paper argues for the primacy of ＂events on the ground＂, and instead focuses on the initiative and choices made by local African actors during the protracted conflict between the Germans and the Hehe in German East Africa （modem Tanzania） in the 1890s. During this conflict, African elites sought to maximize their own power, wealth, and prestige by utilizing German resources to their own ends. Overall, this work argues for the centrality of African politics and policy-making during early colonialism.展开更多

These writers have interesting commonness, especially in two of their novels—Chander Amabasya （Night of No Moon）, by Walilullah and The Outsider by Camus. The protagonists in both of these novels, ArifAli and Meursault respectively, suffer from existentialist crisis, mainly fueled by the impacts of the tarnished history of colonialism and the aftermaths. Even though the stories of the these protagonists take place almost halfway round the world in entirely different settings, the impacts and facades of the crisis are strikingly similar. This paper is a comparative study of soul-searching Arif Ali and Meursault.展开更多

While Omhedi was a contested site of conflict during the war of liberation and served as a stage for ethnographic tours and photography, it has in post-colonial period come to represent a segment of important local power as it is currently the seat of the new Oukwanyama kingship. The central aim of this paper is to explain the transformation of Omhedi as a site of＂spectacles＂ of culture during the colonial period and as the seat of Oukwanyama monarchy in post-colonial Namibia. It centrally asks how the colonial politics of the time influenced the way Omhedi was organized and accessed and the ways in which people attach meaning to and organize a sense of space and place in the postcolonial era. This paper is significant as it explores how political legitimacy can be reactivated at such a contradictory site of＂traditional＂ power like Omhedi and what meanings these hold in terms of access in postcolonial Namibia. I conclude by raising issues of the past with the restoration of the Oukwanyama monarchy and its installation at Omhedi after independence, posing key questions about shifts in political legitimacy in both the colony and the post-colony. My analysis utilizes theories on the important use of landscape as a physical ＂space＂ for living, but also as a ＂place＂ with its meanings and contributions to societal identity. Consequently the place identity is a particular element contributing to sense of place. I argue that there exists a sense of nostalgia that many Ovakwanyama people have for a precolonial past, and the Omhedi landscape serves that purpose. In analyzing these sentiments against the construction of Omhedi as a space and place, this highlights a sense of identity and belonging that many Ovakwanyama people have towards Omhedi in default of any site with deeper legitimation or authenticity.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

Portuguese colonization in Africa produced more recently, mostly in the period 1950-1975, some vast and great material values, of which seven or eight main cities, including the vast contents of their modern architecture, are striking examples. We can evaluate the most positive aspects with future impact represented by this Portuguese architects＇ practice （cultural ethics, use of modern technology, and service to society） and the architectonic work produced during that era. Although these cities and its architecture were created within a late colonial context of indisputable discrimination, they have prevailed despite wars and circumstantial abandonment. Now they represent a consistent material basis for the modernization and/or revitalization of urban life in these countries. Architects that are at present working and intervening in these countries should understand this ambivalence and complementary nature between the ex-colonial ＂concrete city＂ and the ＂informal city＂ pre- and post-colonial, so that their performance is socially and culturally informed, correct, and positive.展开更多

Together with sequences of Bos indicus, Bos taurus, Bos grunniens, and Bos gaurus with Bubalus bubalis as the out group, the partial sequences of Cytb gene of gayals were aligned and base composition and nucleotide variation of Cytb gene were analyzed. The phylogenetic trees were constructed by the NJ method and the MP method respectively, both supporting almost the same topology. Gayal is an independent species of Bos from Bos indicus, Bos taurus, and Bos gaurus. The results also indicate that a great proportion of gayal bloodline was invaded by other species, and the protection of gayal is facing a formidable situation.展开更多

文摘Post-colonial literary studies, as a significant academic field, have recently garnered widespread attention from scholars due to their integration with critical discourse analysis. This study explores the application of critical discourse analysis in post-colonial literary research, focusing on how this method reveals implicit power relations, identity construction, and cultural conflicts within texts. Through in-depth analysis of representative works, this study demonstrates how critical discourse analysis provides new perspectives and methodological tools for post-colonial literary studies. The research finds that critical discourse analysis can effectively deconstruct colonial discourse in texts, reveal authors’ ideological positions, and offer profound insights into understanding the complexity of post-colonial societies. This study not only enriches the methodology of post-colonial literary research, but also provides valuable references for interdisciplinary studies.

文摘Aeration induced turbulence was considered as an important measure to control the occurrence of cyanobacterial blooms in many lakes.Different aeration intensities were set for the culture of Microcystis aeruginosa based on the formation of Microcystis colony at high iron concentrations.The turbulent dissipation rate was calculated using a computational fluid dynamics(CFD)model to evaluate the intensity of turbulence.The effects of turbulence on the formation of Microcystis colony and the release of microcystin were analyzed.Results show that turbulence produced by aeration promoted the growth of Microcystis compared to that in stagnant water.Low intensity turbulence(4×10^(-8)-1×10^(-7) m2/s3)promoted the formation of Microcystis colonies,but high intensity turbulence(1.28×10^(-6)-1.8×10^(-5) m^(2)/s^(3))did not.The increase in the number of cells per colony was slower than that in total biomass,indicating that the low intensity turbulence induced colony formation via cell division,while the high level turbulence disaggregated colonies formed by both cell division and cell adhesion.Low aeration intensity induced more production of reactive oxygen species(ROS)and malondialdehyde(MDA)in the cells of Microcystis than those in high aeration intensity.In addition,the content of microcystin(MC)-LR in the cells was positively correlated with turbulence intensity,showing that turbulence affected not only the growth and aggregation of Microcystis colonies but also their toxin production.These findings provide a better understanding of the cyanobacterial bloom formation mechanisms and help to propose feasible methods to prevent the formation of Microcystis colonies in a natural environment.

文摘In my paper, “Sublimated Colonialism： The Persistence of Actually Existing Settler-Colonialism,” I interrogate the remaining settler-colonialisms that refused to disappear during the epoch of decolonization. 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.

文摘The history of Omhedi in north-central Namibia is not simply about place but is a site that internalizes conflictual and contradictory social forces which are inscribed in place. While Omhedi was a contested site of conflict during the war of liberation and served as a stage for ethnographic tours and photography, it has in post-colonial period come to represent a segment of important local power as it is currently the seat of the new Oukwanyama kingship. The central aim of this paper is to explain the transformation of Omhedi as a site of＂spectacles＂ of culture during the colonial period and as the seat of Oukwanyama monarchy in post-colonial Namibia. It centrally asks how the colonial politics of the time influenced the way Omhedi was organized and accessed and the ways in which people attach meaning to and organize a sense of space and place in the postcolonial era.

I conclude by raising issues of the past with the restoration of the Oukwanyama monarchy and its installation at Omhedi after independence, posing key questions about shifts in political legitimacy in both the colony and the post-colony. My analysis utilizes theories on the important use of landscape as a physical ＂space＂ for living, but also as a ＂place＂ with its meanings and contributions to societal identity. Consequently the place identity is a particular element contributing to sense of place. I argue that there exists a sense of nostalgia that many Ovakwanyama people have for a precolonial past, and the Omhedi landscape serves that purpose. In analyzing these sentiments against the construction of Omhedi as a space and place, this highlights a sense of identity and belonging that many Ovakwanyama people have towards Omhedi in default of any site with deeper legitimation or authenticity.
文摘The post-colonialism is a theory proposed by the eastern colonial academist Edward W. 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.
文摘In Youth volume,Conrad shows his growing criticism of British colonialism.But because of his special favor to Britain,his disaffection with British colonialism is implicit,which is presented by a western voice in Youth,Kurtz’s non-pure British heritage in Heart of Darkness,and Whalley’s pure English seaman in The End of the Tether.

文摘Ancient India and Africa had thousands of years of early economic and cultural exchanges based on the basis of spontaneous equality.As the two sides gradually became colonies of Western countries,they passively changed their original communication methods and modes,and even partly changed them.The relationship between India and Africa during this period was linked to the growth and decline of Western powers in the Indian Ocean region,reflecting the internal governance methods and foreign relations concepts of the non-colonial rulers of India.It has generally experienced the Portuguese colonial period,the period of hegemony and the period of British rule.In a large period of time,the sub-stages such as the rule of the Mughal Empire and the British East India Company can also be detailed.Together,they present a relatively unique picture of historical exchanges between colonial Indo-African countries or regions.
文摘The research on the architecture and urbanism of the former Portuguese Africa allows us to consider and to establish the real intrinsic value, typological and morphological diversity, and the lengthy duration of the legacy of this architectural/urban heritage. Portuguese colonization in Africa produced more recently, mostly in the period 1950-1975, some vast and great material values, of which seven or eight main cities, including the vast contents of their modern architecture, are striking examples. We can evaluate the most positive aspects with future impact represented by this Portuguese architects＇ practice （cultural ethics, use of modern technology, and service to society） and the architectonic work produced during that era. Although these cities and its architecture were created within a late colonial context of indisputable discrimination, they have prevailed despite wars and circumstantial abandonment. Now they represent a consistent material basis for the modernization and/or revitalization of urban life in these countries. Architects that are at present working and intervening in these countries should understand this ambivalence and complementary nature between the ex-colonial ＂concrete city＂ and the ＂informal city＂ pre- and post-colonial, so that their performance is socially and culturally informed, correct, and positive.

文摘Thirty-three mutations and four different haplotypes were found when cytochrome b（Cytb） gene partial sequences of 12 gayals were analyzed. Together with sequences of Bos indicus, Bos taurus, Bos grunniens, and Bos gaurus with Bubalus bubalis as the out group, the partial sequences of Cytb gene of gayals were aligned and base composition and nucleotide variation of Cytb gene were analyzed. The phylogenetic trees were constructed by the NJ method and the MP method respectively, both supporting almost the same topology. Gayal is an independent species of Bos from Bos indicus, Bos taurus, and Bos gaurus. The results also indicate that a great proportion of gayal bloodline was invaded by other species, and the protection of gayal is facing a formidable situation.

文摘Many oases(wet interdunes)are sedimentary systems characterized by high-frequency water-level oscillations,marked changes in salinity and intense biological activity at their margins.They are considered to be one of the most challenging environments on Earth for ecosystem development.These dynamic,depositional settings are usually unfavourable for fossilization and subsequent preservation of vegetal remains.This paper describes bryophyte(liverwort)assemblages occurring in three successive horizons interpreted to represent(i)recurrent early successional phases of biological soil crust colonization of wet interdune margins or(ii)exceptional preservation of floating or riparian liverworts in oasis pond waters associated with a progressive fall of the interdune water level.The record of in situ colonization surfaces characterized by delicate(e.g.lignin-free)three-dimensional structures represents an exceptional type of preservation herein associated with a rapid variation in phreatic interdune water level and the subsequent establishment of anoxic and reducing conditions.The occurrence of exceptionally preserved liverwort colonies coincides with the sedimentary record of,at least,three seismite levels in the oasis.Data gathered from the site suggests that the water table of the oasis was controlled by a combination of(i)a positive creation of accommodation space due to subsidence associated with movement on syn-sedimentary extensional faults,and(ii)the rise and fall of the oasis water table controlled by the oscillations of the groundwater system due to orbital changes which appear to drive the variability of the climate system.Rising groundwater levels flooded the oasis soil crusts and lead to the exceptional recurrent preservation of liverwort colonies at the oasis margins.Alternatively,considering the hypothesis of floating or riparian liverworts in the oasis pond waters,the fall in the level of the oasis water table placed the floating liverworts in contact with the oasis bottom sediments.This fall in the level of the oasis water table could indicate a cessation of accommodation space by syn-sedimentary extensional faults and/or a regional lowering of the groundwater system level associated with drought periods.Preliminary results indicate that oasis lamination between liverwort colonies records decadal and sub-decadal cyclicity,related with 11-year Schwabe sunspot and sub-decadal NAO cyclicities,conferring for every sedimentary cycle between liverwort colonies a duration of approximately 200 years,that otherwise matches the expected recurrence period for the De Vries cycle of solar activity.
