Genotype 3 is the predominant hepatitis C genotype in a multi-ethnic Asian population in Malaysia

BACKGROUND： Genotypes of hepatitis C virus （HCV） are distributed differently across the world. There is a paucity of such data in a multi-ethnic Asian population like Malaysia. The objectives of this study were to determine the distribution of HCV genotypes between major ethnic groups and to ascer- tain their association with basic demographic variables like age and gender.

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.

Racial Differences Effects on Oral Health and Periodontal Diseases Extent, Staging and Grading among the Multi-Ethnic Expatriates in Aseer Region, Saudi Arabia

Background: Given the increase in the numbers of expatriates in Saudi Arabia and the shortage of information about expatriates’ oral health and periodontal disease severity and progression. Objectives: This study aimed to evaluate the effects of the racial differences on oral health and periodontal disease extent, staging, and grading among the multi-ethnic expatriates in the Aseer region, Saudi Arabia. Materials and Methods: This cross-sectional study was carried out on 300 expatriates in Aseer region, Saudi Arabia. They were divided into three equal racial different groups (n = 100), Arabs (AR), Asians (AS), and Africans (AF). The interviews of all participants were completed then the clinical examinations of periodontal diseases extent, staging, and grading parameters were performed. Statistical analysis was done by ANOVA test, Tukey’s test, and Chi-square test. The statistical significance level was determined at p < 0.05. Results: There were statistically significant differences in the comparison between the three ethnic/racial groups in clinical parameters except in GBI, PCR, FI, TFO, and BC, where there were no statistically significant differences in the comparison between the three ethnic/racial groups. There were differences associated with age, gender, smoking, and diabetes, without statistically significant differences among the three racial groups. Conclusion: We concluded that most participants in this study had a generalized severe grade 4 plaque-induced gingivitis and localized periodontitis stage III grade B.

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.

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.

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.

Hybrid Trainable System for Writer Identification of Arabic Handwriting

Writer identification(WI)based on handwritten text structures is typically focused on digital characteristics,with letters/strokes representing the information acquired from the current research in the integration of individual writing habits/styles.Previous studies have indicated that a word’s attributes contribute to greater recognition than the attributes of a character or stroke.As a result of the complexity of Arabic handwriting,segmenting and separating letters and strokes from a script poses a challenge in addition to WI schemes.In this work,we propose new texture features for WI based on text.The histogram of oriented gradient(HOG)features are modified to extract good features on the basis of the histogram of the orientation for different angles of texts.The fusion of these features with the features of convolutional neural networks(CNNs)results in a good vector of powerful features.Then,we reduce the features by selecting the best ones using a genetic algorithm.The normalization method is used to normalize the features and feed them to an artificial neural network classifier.Experimental results show that the proposed augmenter enhances the results for HOG features and ResNet50,as well as the proposed model,because the amount of data is increased.Such a large data volume helps the system to retrieve extensive information about the nature of writing patterns.The affective result of the proposed model for whole paragraphs,lines,and sub words is obtained using different models and then compared with those of the CNN and ResNet50.The whole paragraphs produce the best results in all models because they contain rich information and the model can utilize numerous features for different words.The HOG and CNN features achieve 94.2%accuracy for whole paragraphs with augmentation,83.2%of accuracy for lines,and 78%accuracy for sub words.Thus,this work provides a system that can identify writers on the basis of their handwriting and builds a powerful model that can help identify writers on the basis of their sentences,words,and sub words.
