  • This study examines the contribution of absorptive capacity to the relationship between FDI spillover effects and firm-level green total factor productivity (GTFP) using the Malmquist-Luenberger productivity firm-level data from annual enterprise surveys in Vietnam’s manufacturing and processing industries from 2013 to 2019, the study found that absorptive capacity had an important mediating role in amplifying the beneficial effects of FDI spillover. The magnitude of horizontal FDI spillover varies with absorptive capacity in medium high technology (MHT) sectors, while negative effects are observed in medium low technology (MLT) and low technology (LT)

  • In this article, we investigate the existence, uniqueness and exponential decay of asymptotically almost periodic solutions of the parabolic-elliptic Keller-Segel system on a real hyperbolic manifold. We prove the existence and uniqueness of such solutions in the linear equation case by using the dispersive and smoothing estimates of the heat semigroup. Then we pass to the well-posedness of the semi-linear equation case by using the results of linear equation and fixed point arguments. The exponential decay is proven by using Gronwall's inequality.

  • The overall results imply that private firms will react better to crises due to their quick adaptation ability. State-owned firms’ managers should pay extra attention and formulate contingency plans to counter the complicated bureaucratic structure of State regulation to adapt to the crisis quickly. Regulators and policymakers from developing economies should focus on creating a more transparent system, specifically on how firms should react during times of instability.

  • The study examines the impact of noise trading on stock returns. The investor sentiment index is constructed as a representative of noise trading. This index is extracted from the social network Facebook and the mainstream online newspapers. Based on data collected using the text language analysis method, the author tests a regression model to explain the impact of investor sentiment on the stock returns in the Vietnamese stock market. The result is that sentiment extracted from newspapers positively impacts stock returns over the same period, while sentiment extracted from social networks has no impact. Therefore, investors can use the online newspapers-based investor sentiment index as a tool in technical analysis when making decisions.

  • This study explores the perceived benefits of using phonetic principles in teaching English pronunciation from both teacher and student perspectives. The research examines how incorporating phonetic instruction and Optimality Theory can improve pronunciation accuracy and phonological awareness. Using a mixed-methods approach, the study collected quantitative data through surveys from 57 participants (6 teachers and 51 students) and qualitative insights from focus group interviews with teachers. The results showed that teachers rated the benefits of phonetic instruction higher (mean score of 4.24) compared to students (mean score of 3.31). Teachers highlighted how phonetic principles offer a systematic way to identify and correct pronunciation errors, making teaching more efficient. ...

  • Nghiên cứu xem xét ảnh hưởng của giao dịch nhiễu đến tỷ suất sinh lời chứng khoán và lượng cổ phiếu giao dịch. Chỉ số cảm tính nhà đầu tư được xây dựng là đại diện của giao dịch nhiễu. Dựa trên dữ liệu được thu thập theo phương pháp phân tích ngôn ngữ văn bản, tác giả thực hiện kiểm định mô hình hồi quy để giải thích tác động của cảm tính nhà đầu tư đến tỷ suất sinh lời và lượng giao dịch cổ phiếu trên thị trường chứng khoán Việt Nam. Kết quả cho thấy cảm tính nhà đầu tư có tác động tích cực và trong cùng kỳ đến tỷ suất sinh lời và lượng giao dịch cổ phiếu. Do đó, các nhà đầu tư cá nhân có thể sử dụng chỉ số cảm tính nhà đầu tư như một công cụ trong phân tích kỹ thuật khi ra quyết định.

  • The rapid growth of the global economy has intensified the role of logistics in meeting evolving societal needs but has also exacerbated environmental and sustainability challenges. This study investigates the impact of green logistics practices on sustainable performance, with a focus on both inbound and outbound logistics. The research develops a theoretical framework to explore how green logistics practices affect social, environmental, and economic performance. Using data collected from 221 firms through a structured questionnaire and analyzed via structural equation modeling (SEM), the results reveal that both inbound and outbound green logistics practices positively influence environmental, social, and economic performance. The study contributes to the literature by clarify...

  • We prove the existence and polynomial stability of periodic mild solutions for Boussinesq systems in critical weak-Morrey spaces for dimension n > 3. Those systems are derived via the Boussinesq approximation and describe the movement of an incompressible viscous fluid under natural convection filling the whole space R Using certain dispersive and smoothing properties of heat semigroups on Morrey-Lorentz spaces as well as Yamazaki-type estimate on block spaces, we prove the existence of bounded mild solutions for the linear systems corresponding to the Boussinesq systems. Then, we establish a Massera-type theorem to obtain the existence and uniqueness of periodic solutions to corresponding linear systems on the half line time-axis by using a mean-ergodic method. Next, using fixed...

  • In this article, we investigate the existence, uniqueness, and asymptotic behaviors of mild solutions of a parabolic evolution equations on complex plane, in which the diffusion operator has the form \(\overline{\Box}_{\varphi} = \overline{D}\, \overline{D}^{\ast}\), where \(\overline{D} f = \bar{\partial}f + \varphi_{\bar{z}} f\), the function \(\varphi\) is smooth and subharmonic on \(\mathbb{C}\), and \(\overline{D}^{\ast}\) is the formal adjoint of \(\overline{D}\). Our method combines certain estimates of heat kernel associating with the homogeneous linear equation of Raich \cite{raich06} and a fixed point argument.
