Cybernationalism and cyberactivism in China
El nacionalismo en la era de Internet se está convirtiendo cada vez más en un factor esencial que influye en la agenda-setting de la sociedad china, así como en las relaciones de China con los países extranjeros, especialmente con Occidente. Para China, una mejor comprensión de la estructura teórica universal y de los patrones de comportamiento del nacionalismo facilitaría la articulación social general de esta tendencia y potenciaría su papel positivo en la agenda-setting social. Por otra parte, un estudio del cibernacionalismo chino basado en una perspectiva china en el mundo académico occidental es un intento de transculturación. Desde el punto de vista de las relaciones internacionales y la geopolítica actuales, que son bastante urgentes, este intento ayudaría a mejorar la compatibilidad de China con el actual orden mundial dominado por Occidente, a reducir la desinformación entre China y otros países y a sentar las bases culturales e ideológicas para otras colaboraciones internacionales. Teniendo en cuenta el estado actual de la investigación sobre el nacionalismo chino y la naturaleza participativa de las masas del cibernacionalismo, esta disertación se centra en el cibernacionalismo en las tres partes siguientes. El primero es un estudio de los orígenes históricos del cibernacionalismo chino. Esta sección incluye tanto una exploración del consenso social en la antigua China como un estudio de la influencia del nacionalismo en la historia china moderna. El estudio de los orígenes históricos no sólo nos muestra la secuencia cronológica de la experiencia del desarrollo y la evolución tanto del proto-nacionalismo como del nacionalismo en China, sino que también revela un impulso decisivo para las reivindicaciones y comportamientos actuales del cibernacionalismo. La segunda parte trata del proceso de formación y ascenso del cibernacionalismo desde el siglo XXI. El importante antecedente del paso del nacionalismo al cibernacionalismo es el proceso de informatización de la sociedad china. Una vez completado el estudio de la situación básica de la sociedad china de Internet, especialmente el estudio de los medios sociales como espacio público, podemos vincular Internet con el nacionalismo y examinar el nuevo desarrollo del nacionalismo en la era de la participación de masas. El objetivo final es conectar el proto-nacionalismo, el nacionalismo y el cibernacionalismo, y seguir construyendo una comprensión del cibernacionalismo que sea coherente tanto con los principios universales del nacionalismo como con el contexto chino. Por último, validamos los resultados derivados del estudio anterior a través de la realidad social, es decir, estudiando las prácticas de ciberactivismo del cibernacionalismo para juzgar su suficiencia general así como su validez. Llevaremos a cabo varios estudios de caso de natural language processing basados en big data para reproducir la lógica de comportamiento y el impacto real del ciberactivismo de la manera más cercana posible a la realidad de Internet, evitando al mismo tiempo los defectos de argumentación unilateral y de infrarrepresentación de los estudios de caso tradicionales.Nationalism in the Internet age is increasingly becoming an essential factor influencing agendasetting within Chinese society, as well as China’s relations with foreign countries, especially the West. For
China, a better understanding of the universal theoretical structure and behavioral patterns of nationalism
would facilitate the overall social articulation of this trend and enhance its positive role in social agenda
setting. On the other hand, a study of Chinese cybernationalism based on a Chinese perspective in western
academia is an attempt at transculturation. From the viewpoint of the current rather urgent international
relations and geopolitics, such an attempt would help to enhance China’s compatibility with the current
western-dominated world order, reduce misinformation between China and other countries, and lay the
cultural and ideological groundwork for various other international collaborations. Considering the current
state of Chinese nationalism research and the mass participatory nature of cybernationalism, this dissertation
focuses on cybernationalism in the following three parts.
The first is a study of the historical origins of Chinese cybernationalism. This section includes both
an exploration of the social consensus in ancient China and a survey of the influence of nationalism in modern
Chinese history. The historical origins study not only shows us the chronological sequence of experiencing
the development and evolution of both proto-nationalism and nationalism in China, but also reveals a decisive
impetus for the current claims and behaviors of cybernationalism.
The second part deals with the process of formation and rise of cybernationalism since the 21st
century. The important background for the move from nationalism to cybernationalism is the informatization
process of Chinese society. After we have completed the study of the basic situation of Chinese Internet
society, especially the study of social media as a public space, we can link the Internet with nationalism and
examine the new development of nationalism in the era of mass participation. The ultimate goal is to connect
the proto-nationalism, nationalism, cybernationalism, and furtherly construct an understanding of
cybernationalism that is consistent with both the universal principles of nationalism and the Chinese context.
Finally, we validate the results derived from the previous study through social reality, i.e., by
studying the cyberactivism practices of cybernationalism to judge its general sufficiency as well as validity.
We will conduct several natural language processing case studies based on big data to reproduce the
behavioral logic and actual impact of cyberactivism in the closest possible way to the Internet reality while
avoiding the unilateral argumentation and under-representation flaws of traditional case studies
Could the 21-cm absorption be explained by the dark matter suggested by Be transitions?
The stronger than expected 21-cm absorption was observed by EDGES recently,
and another anomaly of Be transitions would be signatures of new
interactions. These two issues may be related to each other, e.g., pseudoscalar
mediated fermionic millicharged dark matter (DM), and the 21-cm absorption
could be induced by photon mediated scattering between MeV millicharged DM and
hydrogen. This will be explored in this paper. For fermionic millicharged DM
with masses in a range of , the
p-wave annihilation would be dominant during DM
freeze-out. The s-wave annihilation is tolerant by constraints from CMB and the 21-cm absorption. The
millicharged DM can evade constraints from direct detection experiments. The
process of with the invisible decay could be employed to search for the millicharged DM, and future high
intensity sources, such as NA62, will do the job.Comment: 6 pages, 2 figures, the accepted version, EPJ
On Block Cholesky Decomposition for Sparse Inverse Covariance Estimation
The modified Cholesky decomposition is popular for inverse covariance
estimation, but often needs pre-specification on the full information of
variable ordering. In this work, we propose a block Cholesky decomposition
(BCD) for estimating inverse covariance matrix under the partial information of
variable ordering, in the sense that the variables can be divided into several
groups with available ordering among groups, but variables within each group
have no orderings. The proposed BCD model provides a unified framework for
several existing methods including the modified Cholesky decomposition and the
Graphical lasso. By utilizing the partial information on variable ordering, the
proposed BCD model guarantees the positive definiteness of the estimated matrix
with statistically meaningful interpretation. Theoretical results are
established under regularity conditions. Simulation and case studies are
conducted to evaluate the proposed BCD model
O legado colonial japonês e suas atuais implicações políticas no estreito de Taiwan
Although the majority of Taiwan’s population is descended from Chinese settlers who immigrated to the island between the 17th and 19th centuries, the Taiwanese independence movements refuse to accept unification with China, that since its founding in 1949 has claimed Taiwan as its own territory, and insist on designating Taiwan as a separate independent political entity from China. However, the existence of these independence movements is relatively new and begun in the mid-twentieth century, after the end of the fiftieth year of Japanese colonization in 1945. This article aims to analyse how the Japanese colonial and post-colonial experience played an important role in changing the perception of national identity in Taiwan, and currently is the main source of tension in relations with China. The article concludes that the fifty years of Japanese colonization and the violent Chinese repression in the post-war period were essential for the formation of a Taiwanese national identity distinct from the Chinese one and for the emergence of the Taiwanese independence movements.Embora a maior parte da população de Taiwan seja descendente de colonos chineses que imigram para a ilha entre os séculos XVII e XIX, os movimentos de independência de Taiwan se recusam a aceitar a unificação com a China, que desde a sua fundação em 1949 reivindica Taiwan como seu próprio território, e insistem em designar Taiwan como uma entidade política separada e independente da China. No entanto, a existência desses movimentos é relativamente recente e ocorreu partir de meados do século XX, após o fim dos cinquenta anos da colonização japonesa em 1945. O presente artigo tem o objetivo de analisar como a experiência colonial e pós-colonial japonesa tiveram o papel fundamental para a mudança da percepção de identidade nacional em Taiwan, atualmente a principal fonte de tensões nas relações com a China. O artigo conclui que os cinquenta anos de colonização japonesa e a violenta repressão chinesa no período pós-guerra, foram essenciais para a formação da identidade nacional taiwanesa distinta da chinesa e para o surgimento dos movimentos de independência de Taiwan
A democratização de Taiwan e suas implicações nas relações com os Estados Unidos e com a China
Após quase quatro décadas de tranquilidade no estreito de Taiwan, a paz no estreito foi subitamente interrompida em 1995, quando a China lançou uma série de testes com mísseis balísticos contra a costa taiwanesa. A partir de 1995, a China passou a acusar as autoridades de Taiwan de promover a “independência” de Taiwan, e por inúmeras vezes ameaçou Taiwan de guerra. Durante este mesmo período, observou-se o rápido crescimento do nacionalismo taiwanês, fato que influenciou diretamente as recentes crises no estreito de Taiwan. Esta monografia demonstra que as recentes crises (1988-2008), foram resultados diretos da democratização de Taiwan ao final da década de 1980, que aprofundou o histórico conflito entre os dois principais grupos étnico e antagônicos de Taiwan, refletindo-se na política interna e externa de Taiwan
Stream Monitoring and Preliminary Co-Treatment of Acid Mine Drainage and Municipal Wastewater along Dunkard Creek Area
This study investigated coal-mine drainage (AMD) and municipal wastewater (MWW) contaminant concentrations and conducted the combined treatment in phases I and II: phase I, evaluating the effects of mixing the two based on the extent of acid neutralization and metals removal; phase II: conducting anaerobic batch reactor treatment of AMD and MWW under varying COD/sulfate ratios (0.04-5.0). In phase I, acid mine drainage water quality conditions are as follows: pH 4.5, acidity 467.5 mg/L as CaCO3, alkalinity 96.0 mg/L as CaCO3, Cl- 11.8 mg/L, SO4 2- 1722 mg/L, TDS 2757.5 mg/L, TSS 9.8 mg/L, BOD 14.7 mg/L, Fe 138.1 mg/L, Mg 110.8 mg/L. Mn 7.5 mg/L, Al 8.1 mg/L, Na 114.2 mg/L, and Ca 233.5 mg/L. Results of the mixing experiments indicated significant removal of selected metals (Fe 85~98%, Mg 0~65%, Mn 63~89%, Al 98~99%, Na 0~30%), acidity (77~95%) from the mine water and pH was raised to above 6.3. The Phase II results suggested under the wide range of COD/ sulfate ratios, COD and sulfate removal varied from 37.4%-100% and 0%-93.5% respectively. During biological treatment, alkalinity was generated which leads to pH increase to around 7.6-8.5. The results suggested feasibility of the proposed technology for co-treatment of AMD and MWW. A conceptual design of co-treatment system which is expected to remove a matrix of pollutants has been provided to utilize all the locally available water resources to achieve the optimum treatment efficiency. The technology also offers an opportunity to significantly reduce capital and operating costs compared to the existing treatment methodologies used. Featured Application: In this study, we have measured the concentrations of contaminants in acid mine drainage (AMD) and municipal wastewater (MWW) and conducted the combined treatment in phases I and II. This is significant because in previous years there was a massive fish kill that is linked to the high total dissolved solids (TDS) and salinity content in the water. With the current proposed combined treatment technology, it shows high potential in reducing TDS and salinity content in the combined wastewater which will prevent similar accident (Dunkard creek fish kill in 2019) happening again
Periodic and uniform nanogratings formed on cemented carbide by femtosecond laser scanning
Periodic and uniform nanogratings are fabricated by femtosecond laser scanning on cemented carbide. Specifically, three experiments are designed to study the influence of single pulse energy, scanning speed, and scanning spacing on the period and the uniformity of the formed nanogratings. The results show that the sample with single pulse energy of 2 μJ, scanning speed of 1000 μm/s, and scanning spacing of 5 μm shows the best quality of nanogratings among all the tested samples at different processing parameters. The uniformity of the nanogratings is largely determined by single pulse energy, scanning speed, and scanning spacing. Single pulse energy and scanning speed significantly affect the period of the nanogratings, whereas the period of the nanogratings maintains a fixed value under different scanning spacings. The period of the nanogratings increases gradually with the decrease of the single pulse energy and the increase of the scanning speed, respectively
Preventing olanzapine-induced weight gain using betahistine: a study in a rat model with chronic olanzapine treatment
Olanzapine is the one of first line antipsychotic drug for schizophrenia and other serious mental illness. However, it is associated with troublesome metabolic side-effects, particularly body weight gain and obesity. The antagonistic affinity to histamine H1 receptors (H1R) of antipsychotic drugs has been identified as one of the main contributors to weight gain/obesity side-effects. Our previous study showed that a short term (2 weeks) combination treatment of betahistine (an H1R agonist and H3R antagonist) and olanzapine (O+B) reduced (−45%) body weight gain induced by olanzapine in drug-naïve rats. A key issue is that clinical patients suffering with schizophrenia, bipolar disease and other mental disorders often face chronic, even life-time, antipsychotic treatment, in which they have often had previous antipsychotic exposure. Therefore, we investigated the effects of chronic O+B co-treatment in controlling body weight in female rats with chronic and repeated exposure of olanzapine. The results showed that co-administration of olanzapine (3 mg/kg, t.i.d.) and betahistine (9.6 mg/kg, t.i.d.) significantly reduced (−51.4%) weight gain induced by olanzapine. Co-treatment of O+B also led to a decrease in feeding efficiency, liver and fat mass. Consistently, the olanzapine-only treatment increased hypothalamic H1R protein levels, as well as hypothalamic pAMPKα, AMPKα and NPY protein levels, while reducing the hypothalamic POMC, and UCP1 and PGC-1α protein levels in brown adipose tissue (BAT). The olanzapine induced changes in hypothalamic H1R, pAMPKα, BAT UCP1 and PGC-1α could be reversed by co-treatment of O+B. These results supported further clinical trials to test the effectiveness of co-treatment of O+B for controlling weight gain/obesity side-effects in schizophrenia with chronic antipsychotic treatment
