Purpose: This study aims to estimate households' willingness to pay (WTP) in the Mekong River Delta for the improvement of solid waste (SW) management and identify factors influencing willingness to pay for the improvement program. Then, based on the results, this research proposed some policy implications for better SW management. Research methodology: The research employed both Contingent Valuation Methodology - CVM employed parametric and non-parametric approaches to estimate WTP and Logit model to identify the determinants of WTP. Results: The results from a random survey of 400 observations from 3 main cities in the Mekong River Delta (MRD)   indicate that households’ willingness to pay level is from 86,000 Vietnamese Dong (VND) to 110,000 VND/month/household for the non-parametric and parametric approach, respectively (US$1 was equal to 22,890 VND on June 30th, 2021). The results also determine the factors influencing the decision to pay for the program, including bid level, households who have already classified waste, households who intend to support the program, and households’ income. Limitations: In future research, survey areas should be expanded to other developing countries in order to compare and provide a base for proposing better waste management programs in developing countries. Contribution: Future studies should apply both approaches to check the consistency of willingness to pay value elicited. Besides, in order to encourage households to participate in the waste classification program, the authorities need to raise awareness and encourage higher-income households to participate in advance.

Purpose: Every piece of art must, without a doubt, make a statement about itself. This is due to the fact that the more attractive something is, the more symbolic it becomes. Almost all works of art have multiple interpretations. Every great work of literature contains symbols, which add depth, meaning, strength, and dexterity to the work. Research methodology: Two theoretical frameworks, postcolonial and Marxist literary theories, guided the analysis. And this is a qualitative study. Results: The results of this investigation demonstrate that colonial injustice and unmodified colonial institutions and policies are the most enduring issue of Ngugi Wa Thiong’o’s literary exploitation. Limitations: The study is limited to one novel and which is Petals of Blood of Ngugi Wa Thiong’o, written after the post-independence of Kenya. Contribution: Finally, the study found that people are aware of their rulers' actions and are plotting a revolt to break free from the elite's grasp. And it proposes viable answers to their political and socioeconomic problems, such as revolution, not just in Kenya but throughout Africa.

Purpose: The purpose of this study was to identify the causes, factors, and methods to reduce students' exam anxiety in high school exams. Research methodology: In order to conduct this research, from among the students of district one of Rey city and from among 690 seventh grade female students, 100 of them were selected by using a non-random sampling method. The questions in the questionnaire consisted of 21 closed-ended questions and 1 open-ended question. Results: The findings indicate that several factors are effective in aggravating test anxiety. Losing a privileged academic position in the classroom followed by personality impairment disturbs the student's peace of mind and causes students to become anxious during the exam. Limitations: In addition to the factors mentioned as the causes of test anxiety, there may be other factors in these fields that can affect such as hereditary factors, weakness of personality, weakness of faith, and other cases that cannot be measured or not mentioned in this study. Contribution: This study is expected can give a piece of knowledge about the factors that can cause anxiety during exams to students and the method to reduce it.
