DFE-GCN: Dual Feature Enhanced Graph Convolutional Network for Controversy Detection

With the development of social media and the prevalence of mobile devices,an increasing number of people tend to use social media platforms to express their opinions and attitudes,leading to many online controversies.These online controversies can severely threaten social stability,making automatic detection of controversies particularly necessary.Most controversy detection methods currently focus on mining features from text semantics and propagation structures.However,these methods have two drawbacks:1)limited ability to capture structural features and failure to learn deeper structural features,and 2)neglecting the influence of topic information and ineffective utilization of topic features.In light of these phenomena,this paper proposes a social media controversy detection method called Dual Feature Enhanced Graph Convolutional Network(DFE-GCN).This method explores structural information at different scales from global and local perspectives to capture deeper structural features,enhancing the expressive power of structural features.Furthermore,to strengthen the influence of topic information,this paper utilizes attention mechanisms to enhance topic features after each graph convolutional layer,effectively using topic information.We validated our method on two different public datasets,and the experimental results demonstrate that our method achieves state-of-the-art performance compared to baseline methods.On the Weibo and Reddit datasets,the accuracy is improved by 5.92%and 3.32%,respectively,and the F1 score is improved by 1.99%and 2.17%,demonstrating the positive impact of enhanced structural features and topic features on controversy detection.

The Decline of Image of China Under the Background of Rites Controversy in Qing Dynasty

At the turn of the 18th-19th century,in the process of developing missionary business in China,there was a debate about the nature of traditional Chinese sacrificial rites among missionaries,that is,whether the traditional rites of Confucius and Christianity were consistent.With the intervention of the Vatican and the Qing Dynasty,the Chinese rites controversy evolved into the dispute over Chinese imperial power and Roman religious imperial power.The missionary career in China also experienced the transformation from the toleration order,exclusion order and the ticket receiving order to the prohibition order.The sharp opposition between Chinese imperial power and Roman religious imperial power led to the desperate situation of Christian career in China.The missionaries naturally vented their dissatisfaction with China,the good image of China gradually collapsed,and the western image of China began to decline rapidly.

Controversy about the Origin of the Grain Boundary Internal Friction Peak and Its Clarification

In the seventies some scientific workers from France and Italy suggested that the grain boundary internal friction peak (named the K (e) over cap peak in the literature) widely accepted as a grain boundary process, is originated from the motion of lattice dislocations. Since this problem is one of fundamental importance, this controversy has drawn much international attention. Started from 1982, the Hefei research group made a critical analysis of the large amount of literature concerning this problem and,performed a series of crucial experiments to clarify the controversy. It is concluded that the irrelevant evidence suggested by the controverters comes from the farfetched interpretation and the mis-identification of the internal friction peaks appeared under various experimental conditions and different states of the specimens.

Revelation or Reason? Two Opposing Interpretations of the Confucian Classics during the Chinese Rites Controversy

The Four Books were a frequent point of reference in publications during the Chinese Rites Controversy. In the Tian Ru Yin (1664), the Franciscan Antonio de Santa Maria Caballero (1602-69) used an allegorical approach, interpreting the true meaning of the Chinese Classics as Christian revelation while rejecting the traditional reading of the Confucian Classics. On the contrary, the Jesuits in the Confucius Sinarum Philosophus (1687) used a rationalistic approach, harmonizing Western intellectualism with Confucianism. We shall show how these two interpretations are rooted in different theological traditions, leading the two sides to take opposite stances in the Chinese Rites Controversy.

Effectiveness and Controversy of Convalescent Plasma Therapy for Coronavirus Disease 2019 Patients

Since the coronavirus disease 2019(COVID-19)began to spread,it remains pandemic worldwide.The European Medicines Agency’s human medicines committee and Food and Drug Administration have only granted a conditional marketing authorization for remdesivir to treat COVID-19.It is essential to apply other valuable treatments.Convalescent plasma(CP),donated by persons who have recovered from COVID-19,is the cellular component of blood that contains specific antibodies.Therefore,to determine the feasibility of CP for COVID-19,the effectiveness and controversy are discussed in depth here.It is suggested that CP plays a certain role in the treatment of COVID-19.As a treatment,it may have its own indications and contraindications,which need to be further discussed.Meanwhile,it is critical to establish a standard procedure for treatment from CP collection,preservation,transport,to transfusion,and conduct some large sample randomized controlled trials to confirm the transfusion dosage,appropriate time,frequency,and actively prevent adverse outcomes that may occur.

Bufo gargarizans:What’s in a Name?

The taxonomic status of Bufo species in East Asia,particularly those closely related to B.gargarizans,has been controversial for over half a century,and recent molecular studies further fueled the dispute.Whether B.andrewsi,B.bankorensis,B.minshanicus,B.sachalinensis,B.tibetanus,and B.tuberculatus constitute valid species or are geographic or ecological variants of B.gargarizans is at the centre of the discussion.Most of these forms possess morphological diagnostic traits,but those differences are minimal and often inconsistent.Molecular data produced many contradictory patterns.Lack of clear diagnostic characters,different usage or definition of various names,mis-identified specimens,limited amount of data or samples,and frequent inter-specific hybridization may all have contributed to the current controversies.Some contradiction may also result from differences between similarity-based clustering and gene tree-based branching patterns.Nevertheless,a dominant allopatric differentiation pattern within this species complex is apparent,and several regional population groups have been identified.Some of the groups resemble old names(e.g.B.minshanicus,B.tibetanus),while others are new.These groups may represent geographic or ecological variants,incipient species,or valid species,and the current data do not warrant a convincing taxonomic revision.To move forward,a single study with comprehensive sampling and genomic data is needed to establish a solid framework,which will define naturally existing population clusters/lineages,and detect their levels of divergence and approximate geographic boundaries.Morphological and ecological examination will follow to understand their biology,determine their taxonomic status,and identify consistent diagnostic characters if necessary.
