Bệnh dịch tả heo Châu Phi (ASF) xảy ra lần đầu tiên ở huyện Phú Tân, tỉnh An Giang vào tháng 7/2019 và nhanh chóng lây lan khắp 18/18 xã và thị trấn trên địa bàn huyện. Nghiên cứu được thực hiện nhằm khảo sát một số đặc điểm dịch tễ và kiểu gene của virus gây bệnh ASF. Kết quả điều tra hồi cứu thông qua các số liệu được thu thập từ các báo cáo của các cơ quan có thẩm quyền cho thấy tỷ lệ các cơ sở xuất hiện ASF là 29,85% và tỷ lệ heo bị tiêu hủy là 27,37%. Có sự khác biệt về tỷ lệ tiêu hủy theo loại heo, trong đó tỷ lệ tiêu hủy cao trên heo giống sinh sản, cao nhất là trên heo đực giống (100%), kế đến là heo nái (34,24%), heo thịt (26,83%) và thấp nhất là heo con (24,96%). Đặc điểm di truyền của virus ASF lưu hành tại huyện Phú Tân được khảo sát trên cơ sở một phần của đoạn gene B646L (p72) của 4 chủng virus đại diện, kết quả cho thấy đoạn gene p72 của 4 chủng virus được phát hiện tại huyện Phú Tân tương đồng 100% với đoạn gene tương ứng của các chủng virus đã được phát hiện trước đ...

The purpose of this paper is to examine risk management of the Vietnamese banking system. This is the first such study of the Vietnamese banking system. To be able to carry out a comparative analysis and provide policy recommendations for risk management, we carry out an original survey of Vietnamese commercial banks using a questionnaire. 42% of the interviewees are General/Deputy General Directors and 58% are Heads/Deputies of a risk management department. The Kruskal-Wallis, Pearson chi-square and other tests are employed to examine the relationship between risk management and bank efficiency. The survey results indicate that there is a difference between banks in terms of risk area identification, risk intensification methods prioritised, risk monitoring methods, efficiency improvement suggestions, awareness of other banks’ risk management systems and credit risk analysis.

It is not deniable that pronunciation is considered one of the most crucial parts of learning English helping learners enhance their communication in both speaking and listening comprehension. To reach a level of a clear and precise pronunciation has never been an effortless task; however, it is a far more problematic one for English majored students regardless of their learning years. For this reason, the study entitled “Common Errors in Pronouncing Dental Sounds of English-Majored Sophomores at Tay Do University” was implemented with the aim at investigating the errors that English-majored students encountered in pronouncing dental sounds. 80 English-majored sophomores from course 14 at Tay Do University were selected to participate in the study. Questionnaires and recording tests were delivered to the participants for collecting data and getting more information. The collected data from the two instruments mentioned above was all analyzed afterward. The findings of the research r...

Through employing a quantile regression approach and a dataset of 206,046 firm‐year observations over the period 1970–2017 in the United States market, we examine the heterogeneity and asymmetry in the speed of adjustment (SOA) towards target leverage. We document that high‐ and low‐levered firms adjust more quickly towards their target levels than do mid‐levered firms. This holds true when total leverage and long‐term leverage are considered in the analysis. Second, there is a difference in SOA between low‐ and high‐levered firms, which points to SOA skewness. Third, when short‐term leverage is considered in the analysis, the adjustment speed becomes smaller at varying levels of short‐term debts. Finally, empirical evidence from total leverage and long‐term leverage adjustments is consistent with the trade‐off theory, whereas empirical evidence from short‐term debt adjustments supports the pecking order theory.

PurposeThe purpose of this paper is to examine the degree of concentration and efficiency in the Vietnamese banking system using the structural model.Design/methodology/approachThe authors apply the concentration ratio (CR), Herfindahl‐Hirschman Index (HHI) and concentration‐profitability model based upon the Structure‐Conduct‐Performance (SCP) and Efficiency Hypothesis (EH) approaches to examine 48 Vietnamese commercial banks over the period 1999‐2009.FindingsThe authors' empirical results show that the Vietnamese banking industry has become substantially less concentrated; however, large commercial banks still dominate the whole banking system. Further, their results do not support either the traditional Structure‐Conduct‐Performance or the Efficiency Hypothesis.Practical implicationsThe State Bank of Vietnam needs to have policies for restructuring the system and promoting competition in the banking sector of Vietnam.Originality/valueThis is the first such study of the Vietna...
