On the Changes of Chinese Appellation Since 1949

As a component of language,Chinese address terms plays equally important roles with other parts of language in dailylife.The following analyses try to focus on the changes of Chinese Appellation since"the founding of PRC"and discuss the factorsbehind them.

A Comparative Analysis of the Chinese and English Appellation

Appellation not only reflects the social relationship between human beings,but also shows the social structure and culture in different countries,regions and societies.This paper focuses on the comparison of appellation in these two languages and analyses the reasons for this difference from cultural and psychological aspects.

The Importance of Professional Training for Test Writers

The purpose of this essay was to explore the importance of professional training for test writers and teachers as well.Since both testing and teaching are so closely interrelated that it's impossible to work in either field without being constantly concerned with the other. Test writers need professional training to keep pace with emergence of new views of language teaching practice and the rapid change of social life, in order to make testing more authentic and more valid.

On Etymology of the Appellation“Da man-er”(大嫚儿)in Qingdao Dialect

The appellation to call a girl in Qingdao dialect is“da man‐er”(大嫚儿),which is supposed to derive from German word“Damen”phonetically,according to:(1)remarkable similarities in meaning,pronunciation,and consistencies in commendatory or derogatory senses;(2)different preferences for people in different ages;and(3)the insertability of modifiers(adjectives or nouns)for“xiao man‐er”(小嫚儿)and the non‐insertability for“da man‐er”(大嫚儿).Therefore,nearly 100 years during the changing processes,“da man‐er”(大嫚儿)has a series of derivations commonly referring to the appellations of“girl”,such as“man‐er”(嫚儿),“man gu zi”(嫚姑子),“xiao man‐er”(小嫚儿)and even the formation of“xiao(小)+adj/n+man‐er”(嫚儿).

Reflections on Language Testing——From the Perspective of Professional Training for Test Writers

On the Challenges Imposed on the Language Test Writers

Assessment in the classroom,whether informal,formative,or summative,has been the major source of identifying students’ strengths and weaknesses in learning a foreign language. The article tries to rationalize the current test writers training programs by elaborating on the importance of testing and assessing from the perspectives of the criteria of qualified testing system and the qualifications of test writers which reversely turns to be the challenges imposed on the language test writers.

Popular Female Appellation: the Compare Study of "meinv" and "Xiao jiejie"

Female appellations are changing with time,which has attracted many attention from scholars.In the last century,"xiaojie"was very popular.The word"xiaojie"was then replaced by"meinv"because of its negative images.Nowadays,with the development of network buzzwords,the word"Xiao jiejie"gradually come into the public eye.In this paper,I will compare these two female appellations"meinv"and"Xiao jiejie"from four aspects:the introduction of origin and population,the characteristics of word structures,target users,and the pragmatics effects.

Cultural Identity on Afro- American Women Writers

Afro- American Women were once a social minority and the weaker gender in American society. Through the endeavor of a group of Afro- American women writers,they have achieved a great success for the cultural identity by concluding their own social experience into works in recent decades. This paper reviews the cultural identity built by Afro- American black women writers and introduces its historical reasons,works,and historical significance. By doing this,we stand to gain insights into the American women writers and find their great contributions to their cultural identity in American culture.

AN ALGEBRAIC APPROACH TO DEGENERATE APPELL POLYNOMIALS AND THEIR HYBRID FORMS VIA DETERMINANTS

It is remarkable that studying degenerate versions of polynomials from algebraic point of view is not limited to only special polynomials but can also be extended to their hybrid polynomials.Indeed for the first time,a closed determinant expression for the degenerate Appell polynomials is derived.The determinant forms for the degenerate Bernoulli and Euler polynomials are also investigated.A new class of the degenerate Hermite-Appell polynomials is investigated and some novel identities for these polynomials are established.The degenerate Hermite-Bernoulli and degenerate Hermite-Euler polynomials are considered as special cases of the degenerate Hermite-Appell polynomials.Further,by using Mathematica,we draw graphs of degenerate Hermite-Bernoulli polynomials for different values of indices.The zeros of these polynomials are also explored and their distribution is presented.

Re- Thinking Classic Marxist Writers＇ Explications on Nationalism： on the ＂Difficult Dialogue between Marxism and Nationalism＂

Both Marxism and nationalism are among the most far-reaching thoughts in modern times.On dealing the ideological collision between Marxism and nationalism, "Difficult Dialogue" universally exists in the academic circle.Many scholars evaded,ridiculed or even negated classic Marxist writers' explications on nationalism.Though basically,classic Marxist writers criticize nationalism,it doesn' t mean that Marxism and nationalism inevitably oppose to each other.It is highly necessary to analyze the causes of the "difficult dialogue between Marxism and nationalism" and re-thinking classic Marxist writers' explications on nationalism.

A Revision Model in Writing for Novice Writers with a Focus on Audience and Feedback

Revision is a complex,yet important phase in writing to improve the quality of a text.Some revision models are created to explain its components and the ways these components work.However,analysis of available models shows that they are proposed mainly for expert writers,who can complete the complex revision process individually,without the need of support or feedback.Most of the available revision models also do not include audience as a component.Therefore,the purpose of this paper is to introduce an alternative revision model for novice writers at or higher than highschool level with a focus on audience and feedback.First,the definition of revision is made,which is followed by summaries of the importance of audience and feedback in writing.Second,available revision models in literature that serves as the basis of the alternative model are reviewed.Finally,the alternative revision model is introduced with its components and the way these components work is explained.The revision model presented in this paper will contribute to literature on writing by filling the gap in revision models by proposing a model for novice writers and highlighting the importance of audience and feedback.

Supervised Feature Learning for Offline Writer Identification Using VLAD and Double Power Normalization

As an indispensable part of identity authentication,offline writer identification plays a notable role in biology,forensics,and historical document analysis.However,identifying handwriting efficiently,stably,and quickly is still challenging due to the method of extracting and processing handwriting features.In this paper,we propose an efficient system to identify writers through handwritten images,which integrates local and global features from similar handwritten images.The local features are modeled by effective aggregate processing,and global features are extracted through transfer learning.Specifically,the proposed system employs a pre-trained Residual Network to mine the relationship between large image sets and specific handwritten images,while the vector of locally aggregated descriptors with double power normalization is employed in aggregating local and global features.Moreover,handwritten image segmentation,preprocessing,enhancement,optimization of neural network architecture,and normalization for local and global features are exploited,significantly improving system performance.The proposed system is evaluated on Computer Vision Lab(CVL)datasets and the International Conference on Document Analysis and Recognition(ICDAR)2013 datasets.The results show that it represents good generalizability and achieves state-of-the-art performance.Furthermore,the system performs better when training complete handwriting patches with the normalization method.The experimental result indicates that it’s significant to segment handwriting reasonably while dealing with handwriting overlap,which reduces visual burstiness.

An Unsupervised Writer Identification Based on Generating Clusterable Embeddings

The writer identification system identifies individuals based on their handwriting is a frequent topic in biometric authentication and verification systems.Due to its importance,numerous studies have been conducted in various languages.Researchers have established several learning methods for writer identification including supervised and unsupervised learning.However,supervised methods require a large amount of annotation data,which is impossible in most scenarios.On the other hand,unsupervised writer identification methods may be limited and dependent on feature extraction that cannot provide the proper objectives to the architecture and be misinterpreted.This paper introduces an unsupervised writer identification system that analyzes the data and recognizes the writer based on the inter-feature relations of the data to resolve the uncertainty of the features.A pairwise architecturebased Autoembedder was applied to generate clusterable embeddings for handwritten text images.Furthermore,the trained baseline architecture generates the embedding of the data image,and the K-means algorithm is used to distinguish the embedding of individual writers.The proposed model utilized the IAM dataset for the experiment as it is inconsistent with contributions from the authors but is easily accessible for writer identification tasks.In addition,traditional evaluation metrics are used in the proposed model.Finally,the proposed model is compared with a few unsupervised models,and it outperformed the state-of-the-art deep convolutional architectures in recognizing writers based on unlabeled data.

WTO争端解决机制改革的现状与未来——部长级会议决定解读

从2022年开始,WTO争端解决机制改革谈判陆续展开,并且在第十三届部长级会议前取得了一定成果,形成了谈判文本。谈判是在美国主导下进行的,谈判文本的核心是回应美国关注。然而,美国仍然不同意恢复上诉机构,以至于谈判文本中的上诉/审议部分出现空缺。由此可见,谈判是以争端解决其他方面改革换取美国对上诉机构的支持,但是这一目标没有实现。有鉴于此,加上成员意见分歧和美国大选在即,争端解决改革谈判的前景不容乐观,WTO成员应该考虑更多路径,包括使用上诉仲裁和新立上诉机构。
