As a coastal district located in the Southeast of Ho Chi Minh City (HCMC), Vietnam, Can Gio is characterized by low average terrains ranging up to only 1.5m above the sea level. Impacted by climate change and sea level rise in recent years, certain neighborhoods in the Can Gio District have been facing the loss of their residential and arable lands, as well as undesired relocations. Together with riverbank and coastal erosion, this phenomenon has several negative impacts on the lives of people in residential areas and on their economic activities. This research uses a literature review and observation as the main methods to explore the experiences of sea level rise adaptive housing and thereby suggests certain solutions for the Can Gio District. The solutions include saving space for water, elevating floors, constructing with floating floors, and creating biological ditches and osmotic lines to help quickly drain flooded water. These solutions aim to protect people’s lives and houses against the rising sea level and ensure the sustainable development of the neighborhoods.

A diverse board has been seen as an important factor contributing to the success andsustainability of a company. Therefore, policies to enhance the diversity of the boards havebeen implemented in many countries around the globe. However, previous findings on theimpact of female leaders on firm performance still remain inconclusive. Using a dataset of 20Vietnamese commercial banks over the period from 2013 to 2019, this paper examines whether the gender of the bank leaders such as CEOs or members of Management Team (MT), Board of Directors (BOD) have an impact on bank profitability and bank stability in Vietnam. Our findings suggest that banks with female CEOs tend to be more profitable and more stable than those with male CEOs. However, more women appointed to MT do not necessarily result in more profitable or more stable banks. More interestingly, the presence of women on banks’ board of directors implies lower profitability and more vulnerability for banks. Obtained findings imply important bank governance policies toward better performance and stability for commercial banks in Vietnam.

In the current study, using Cleistocalyx operculatus bud extracts to synthesize silver nanoparticles is considered a novel, eco-friendly, and low-priced process that advances chemical and physical methods. Cleistocalyx operculatus bud extracts played a dual part in reducing and stabilizing silver nanoparticles. The formation of silver nanoparticles was recognized on UV-Vis spectra at an absorption maximum of 432 nm. Transmission electron microscopy images detected the quasi-spherical nanoparticle shape with an average size of 26.2 nm corresponding with water extract and 27.5 nm synthesized by ethanol-water extract. The obtained silver nanoparticles had moderate stability with zeta potential ranging from −15.4 to −38.4 mV. The phase purity of the bio-synthesized materials was confirmed by an X-ray diffraction pattern. The Fourier-transform infrared analysis demonstrated hydroxyl groups acting as stabilizing agents in the extract. Silver nanoparticles synthesized from ethanol-water extract exhibited higher antibacterial and anticancer activity than nanomaterials prepared with water extract. Positive-gram bacteria (Bacillus subtilis, Lactobacillus fermentum, and Staphylococcus aureus, negative-gram bacteria (Escherichia coli, Pseudomonas aeruginosa, and Salmonella enterica), and cancer cell lines (lung cancer A549, hepatic cancer Hep-G2, epidermal carcinoma KB, and breast cancer MCF-7) were both inhibited by the nanoparticles synthesized with ethanol-water extract.
